No. 62 / 609,027, filed in their entirety. The body is incorporated herein by reference.
[0002] The present disclosure relates to golf clubs. More specifically, the present disclosure relates to colored coated fibers. Composite materials having, for example, a composite sole or crown with a colored coated fiber For golf clubs such as wood type golf clubs having a lightweight club head structure including a insert Regarding. [Background technology]
[0003] Modern "wood-type" golf clubs (especially "drivers" and "fairway woods") and "utility or hybrid clubs") are made of strong, lightweight metals, such as titanium. They tend to be made from cellulose, so they are commonly called "metal woods." An exemplary metal wood golf club, such as a fairway wood or a saddle wood, typically has a The golf club includes a hollow shaft and a club head connected to the lower end of the shaft. The rub head is made of a strong, yet lightweight metallic material, such as titanium, steel, or an aluminum alloy. There are also heads made at least in part from carbon fiber composite materials. The use of these materials has resulted in the larger club heads that golfers currently demand. A club head, i.e., a club head with a volume of at least 300cc and up to about 500cc. The larger size but conventional weight of the club head is advantageous for some Make it easier for golfers to launch the golf ball through the air with greater precision , providing a larger "sweet spot" on the striking face and a club's moment of inertia. We aim to provide.
[0004] Titanium alloys are particularly popular in club head designs for their combination of strength and light weight. However, the materials can be very expensive. Steel alloys are more economical, but Because the density of titanium is greater than that of titanium alloys, steel clubheads can be made with less force while still maintaining their durability. Therefore, the size is limited in order to maintain the head weight within the conventional range.
[0005] For example, a composite club head, such as carbon fiber reinforced epoxy or other polymer, may be used to improve the feel of a metal club. head replacement. A notable advantage is its relative light weight compared to stainless steel alloys. However, these club heads do not offer the durability and performance associated with composite materials. These include higher labor costs during manufacturing and unnecessary use of composite materials. Sound absorption properties are included.

[0086] The following describes embodiments of golf club heads in the context of a driver-type golf club. As will be explained, the principles, methods and designs described may be used, in whole or in part, in a fairway wood. The present invention is applicable to golf clubs, utility clubs (also known as hybrid clubs), etc. .
[0087] A golf club including one or more components at least partially constructed from a composite material, It can provide beneficial properties to the golfer. For example, it can be made of two or more materials (e.g., gold). Golf club heads constructed from metals and composites have properties that are beneficial to golfers (e.g. For example, weight characteristics, sound characteristics, size characteristics, and center of gravity characteristics can be provided. Thus, a composite club head may comprise a metal body and one or more inserts that include a composite material. For example, the composite insert may comprise a portion of the crown of the club head. The composite material may define a portion of the sole of the club head. Composite inserts improve the mechanical properties of the club head due to the lightweight and high strength properties of composite materials. A given club head shape can be achieved without sacrificing properties (e.g., strength and impact performance attributes). This can help reduce weight.

[0184] In some embodiments, the golf club head 10 includes a body of the golf club head 10. A rear weight track 30 (or rear weight track) located on the sole portion 17 of the The rear weight track 30 may include a front weight track 30 or a rear weight track 30. The weight 32 (or weight assembly 32) defines a track on which the weight 32 (or weight assembly 32) is slidably mounted. In some implementations, the weights 32 are attached to the rear weight track 30 by fastening means, e.g. For example, the weight 32 is slidably mounted by a screw 34. In some implementations, the weight 32 is a multi- For example, the weights 32 are bonded together to form the weights 32. The weight components may include first and second weight components 32a, 32b that are mated together. In implementation, the weight 32 is attached to the tensioner 32 so that the fastening means is placed under tension, i.e., in a tension system. The rear weights are attached by clamping at least one part of the rack, e.g. the ledge. The weight 32 may be secured to the track 30. Additionally or alternatively, the weight 32 may be secured to the track 30 when the fastening means is compressed.

[0185] As will be discussed in more detail below, the rear weight track 30 provides the user with additional adjustments. By moving the weight closer to the hitting surface, the clubhead can be lower and further forward. This allows the ball to have a lower spin due to the CG being closer to the ball. Generally, higher lofted clubs are considered "easier" to hit. It is also possible to increase the loft of the club head. By moving the weight rearward, the moment of inertia (MOI) is increased, resulting in a more powerful club. A club with a higher MOI generally has a higher spin rate. Therefore, the rear weight track 30 allows the At least both pin and MOI adjustments are possible.
[0186] As shown, the rear weight track 30 has various weights along the rear weight track 30. At least one weight assembly in a suitable position, e.g., either forward or rearward. Two or more weights may be used in any one of a variety of locations. and / or the presence of multiple weight ports strategically placed on the club head body. For example, the golf club head 10 may include a toe weight port and a heel weight port. The user may then select either the draw or fade bias. To promote this, more weight can be moved to either the toe or the heel. In addition, it is possible to divide any weight between the front and rear positions. This results in a higher MOI club, while also placing all the weight in the front part of the club. By moving the club head to the center, the club head will have a low forward CG. The “forgiving” higher MOI clubs or clubs that produce a lower spin ball It is believed that a choice can be made between

To adjust the effective CG of the club head 10, the The golf club may be selectively loosened or tightened for adjustable adjustment. The performance of the golf club head 10 can be improved by adjusting the CG of the golf club head 10 laterally. The characteristics of the golf ball hit by the golf club head 10 are adjusted. In particular, the control of the flight characteristics, such as the side spin characteristics, of the golf ball is facilitated. , two weights that can be adjusted independently of each other (e.g., first and second weights 38, 3 9) allows for adjustment and interaction between weights. For example, both weights are , completely in the toe region 14 and completely in the heel region 16, at the maximum distance from each other, One weight is located completely in the toe region 14 and the other weight is located completely in the heel region 16, In the center or middle position of the lateral weight track 36 or in other weight position patterns Additionally or alternatively, the first and second weights 38, 39 may be positioned at the rear The rear weight track 30 is configured so that there are two or more weights located on the rear weight track 30.

[0242] Filed June 11, 2001, which is incorporated herein by reference in its entirety. The invention is entitled "METHOD FOR MANUFACTURING AND GOL As described in detail in U.S. Patent No. 6,623,378 for "F CLUB HEAD" As such, the crown or outer shell of the golf club head 10 is made of carbon fiber reinforced epoxy, carbon The device may be made of composite materials such as fiber-reinforced polymer or polymer. In application Ser. Nos. 10 / 316,453 and 10 / 634,023, a lightweight crown is used. Further, a golf club head having the above-mentioned configuration is described in U.S. Patent Application Serial No. 12 / 974,437. (now U.S. Pat. No. 8,608,591) has a lightweight crown and sole. A golf club head is described.

(including the above).
[0244] In certain embodiments, composite materials useful for manufacturing golf club head components include The fiber portion and the resin portion are generally made of a material in which the fibers are embedded in a predetermined manner. In the composite material for the club head, the fiber portion is made of resin. It is constructed as a number of layers or plies of fibre impregnated with a grease component. Each layer has its own orientation, which typically varies from layer to layer and is precisely controlled. A useful number of layers is a substantial number, for example, 40 or more. However, the number of layers may vary depending on the sole or crown. In this case, the number of layers can be substantially reduced, for example, to 3 or more, 4 or more, 5 or more, 6 or more. Examples are provided below. During the processing of a composite material, layers (each layer being an uncured or partially cured resin) are Each such layer is called a "prepreg" layer. The prepreg laminates are then stacked together in a "laminate" fashion. The resin is cured to a rigid state. Depending on the interest, specific strength can be calculated by dividing the tensile strength by the density of the material. This is also known as the strength-to-weight ratio or strength / weight ratio.
[0245] In testing of certain club head configurations, a relatively low fiber-based average weight (FAW) was Composite sections made from prepreg plies with excellent performance in several areas, e.g. For example, it has been found to provide impact resistance, durability, and overall club performance. FAW is the fiber weight (unit: g / m2) of a given amount of prepreg. 2 ) The lounge and / or sole panels are 20 g / m 2 ~200g / m 2 A composite having a fiber basis weight of It may be made of plies of composite material, but not exceeding 100 g / m 2 More preferably, 75g / m 2 The following FAW values may be particularly effective: A particularly suitable fiber material for this purpose is the carbon fiber described above. Two or more fiber materials may be used. However, in other embodiments, 70 g / m 2 FAW value below 100g / m 2 Prepreg plies having FAW values above 10 ... The thickness is 70g / m 2 The main prohibition factor for prepreg plies with FAW values below be.
[0246] In certain embodiments, multiple low FAW prepreg plies can be stacked together, It also has a relatively uniform distribution of fibers through the thickness of the ply. Prepreg materials with higher FAW at resin content (R / C unit:%) levels The laminate plies have significantly more resin-rich areas than the laminate plies of low FAW material, especially adjacent In particular, the forces generated by the impact of a golf ball tend to be large at the interface between the plies. Since the orientation of the fibers in the fiber reinforcement is generally transverse to the orientation of the fibers in the fiber reinforcement, the resin-rich regions The prepregs used to form the panels tend to reduce the effectiveness of the fiber reinforcement. The ply desirably comprises carbon fibers impregnated with a suitable resin, such as, for example, epoxy. An exemplary carbon fiber has a tensile modulus of 234 Gpa (34 Msi) and a strength of 4500 Mpa "34-700" carbon fiber (Grafil, S) with a tensile strength of 650 Ksi (Available from Grafico, California). The fiber has a tensile modulus of 240 Gpa (35 Msi) and a compressible strength of 4900 Mpa (710 ksi The preferred epoxy resin is type TR50S carbon fiber, having a tensile strength of 1.0001%. "301" and "350" (Newport Adhesives and Compo (Available from the Irvine, Calif. site). Exemplary resin content (R / C) is 33% to 40%, preferably 35% to 40%, more preferably 36% to 3 The rate is 8%.
[0247] Golf club heads discussed throughout this application (e.g., golf club head 10) Some embodiments of the present invention are made of carbon fiber reinforced epoxy, carbon fiber reinforced polymer, or polymer. The crown, sole, and / or face of the golf club may be made of separate materials, such as a composite material. Alternatively, the crown, sole, and / or face may be The surface may be made of a material with low density, such as titanium or aluminum. A part of the round is made of steel (approximately 7.8 to 8.05 g / cm 3 ) or titanium (approx. 4.43g / c m 3 ), but the majority of the crown is made of a less dense material, e.g. Approximately 1.5 g / cm 3or about 4.43 g / cm 3 Has a density less than That is, the crown may be made of some other metal or some other material. Additionally or alternatively, the face may be a part of the sole. Thus, they may be welded in place rather than cast.
[0248] By manufacturing the crown, sole, and / or face from a material with a low density, The weights may be moved from the crown, sole, and / or face to other areas of the club head, e.g. For example, the low front and / or low rear can be redistributed. Both are suitable for club heads that include weight tracks that slide from front to rear. It is possible.

In addition, improvements have been made to the sole and / or crown. For panels that are placed in a space, the layers can be substantially reduced to 3, 4, 5, 6, 7 or more layers. do.
[0251] Table 1 below provides examples of possible laminates. These laminates are made of woven fabric plies. Without mentioning, a crown and / or sole construction that may use unidirectional plies The structure shown is for a quasi-isotropic laminate. A single ply is approximately 3 70g / m2 with a resin content of 6% to about 40% 2 For a standard FAW of about 0.06 The crown and / or sole panels may have a thickness ranging from 5 mm to about 0.080 mm. is 20g / m 2 ~200g / m 2 The composite material may be formed of plies having a fiber basis weight of In some embodiments, the plies of the insert are in the range of 0.065 mm to 0.60 mm. For example, the thickness of the ply may be 0.065 mm, 0.025 mm, ... .10mm, 0.20mm, 0.30mm, 0.40mm, 0.50mm, 0.60mm , or a range having any two of these values as endpoints. The length may be altered by adjusting either the FAW or the resin content. Therefore, the overall laminate thickness may be altered by adjusting these parameters. . [Table 1]
[0252] The weight per unit area (AW) is calculated by multiplying the density and thickness. For the ply shown, the density is approximately 1.5 g / cm 3 For titanium, The strength is about 4.5g / cm 3 Depending on the material and number of plies used, composite crowns are And / or the thickness of the sole is about 0.195 mm to about 0.9 mm, preferably about 0.25 mm to about 0.75 mm, more preferably about 0.3 mm to about 0.65 mm, and even more preferably Or, it is in the range of about 0.36 mm to about 0.56 mm. These ranges are for the crown and Although the ranges are given for both the crown and the sole, these ranges are given for the crown and the sole having the same thickness, It should be understood that this does not necessarily mean that the components will be made of the same materials. In certain embodiments, the sole may be made from either a titanium alloy or a steel alloy. Similarly, the body of the golf club head 10 may be made from either a titanium alloy or a steel alloy. Titanium is typically 0.4 mm to about 0.9 mm, preferably 0.4 mm. ~ about 0.8 mm, more preferably 0.4 mm ~ about 0.7 mm, and even more preferably 0 In some instances, the crown and / or sole may range from 0.45mm to approximately 0.6mm. The thickness may be non-uniform, for example, from about 0.45 mm to about 0.55 mm. Change.
[0253] In particular, the thin titanium construction (0.4 mm to 0.5 mm) in other parts of the golf club head 10 0.9mm), the use of composite materials in the crown and / or sole A significant amount of optional weight can be freed up. Thinner titanium construction increases the difficulty of manufacturing. In the past, over 100 golf clubs were cast at once. The head could be cast in a short time, but the thinner construction allowed for higher yields and less material usage. To achieve the desired combination of functions, the golf clubs cast per cluster are There will be fewer threads.
[0254] The key strategy to gain more arbitrary weight is to reduce the wall thickness of the golf club head 10. The aim is to make it easier. 3 of volume (i.e., driver) and 100 cm 2 No For a typical titanium alloy "metal wood" club head with a round area, The thickness of the crown is typically about 0.8 mm and the weight of the crown is about 36 g. Therefore, reducing the wall thickness by 0.2 mm (e.g., from 1 mm to 0.8 mm) This could result in a "saving" of any weight of .0g.
[0255] The following example shows the possibilities of fabricating a composite crown instead of a titanium alloy crown. It may be useful to illustrate some weight "savings" by, for example, reducing the thickness of the material to about 0. By thinning it to .73mm, it weighs approximately 25.0g less than a 0.8mm titanium alloy crown. This results in an additional optional weight "saving" of 0.73 mm. For example, reducing the material thickness to about 0.73 mm. This means that the titanium alloy crown weighs approximately 25g more than the 0.8mm titanium alloy crown, or 1.0mm more. This is an additional optional weight "saving" of 34g over the crown. In addition, the composite crown is 0.6mm thick. If you use a 0.8mm titanium alloy crown, you can get an additional 27g of any weight. Furthermore, a 0.4mm composite crown can be fitted with a 0.8mm titanium alloy crown. The crown is a further optional weight "saving" of about 30g over the previous model. For example, in order to achieve about 0.32 mm thickness, about 0.26 mm thickness, about 0.195 mm thickness, However, the thickness of the crown may change over time due to normal use and abuse. This must be balanced against the overall durability of the crown. For example, an unprotected crown That is, the uncovered crown is not in contact with any other wood or a club in the golf bag. There is a risk of injury in a collision with Ian.
[0256] For example, the crown is 20 g / m 2 ~200g / m 2 A composite material having a fiber basis weight of The weight of a composite crown is comparable to that of a similarly sized, metal-made body. The composite crown weighs at least 20% less than the standard single tape crown. The tape may be formed of at least four plies of modulus graphite, the plies being made of a single tape. may be oriented at any combination of 0 degrees, +45 degrees, -45 degrees, and 90 degrees. Or alternatively, the crown may include an outermost layer of woven graphite cloth.

The hosel 4538 is recessed relative to the club shaft (e.g., shaft 1 02). The opening 4522 defines an opening 4539 for receiving a distal end of the face insert. The face support 4524 and the moving zone 4510 are repositioned by the reception. The transfer zone 4540 is connected to the solenoid 4540 to surround the front opening 4522. crown-lip region 4524a, heel-lip region 4524b, crown-lip region 4524c, 4c, and toe-lip region 4524b. These portions may be continuous. The ridges may be spaced apart or may be intermittent with spaces between them.
[0273] In some embodiments, at least a portion of the face insert 4510 is hardened. Fibrous material (e.g., graphite or carbon fibre) embedded in a resin (e.g., epoxy) For example, the face insert 45 may be made of a composite material including multiple plies or layers of 10 is a composite component (e.g., FIG. 46 ) having an outer polymer layer that forms a striking surface 4512. The outer coating or cap may include a component 4600 shown in FIG. Examples of suitable polymers that can be used to form the polymer are described in detail below. Generally, the face insert 4510 is incorporated herein by reference in its entirety. The face insert 4510 as described in U.S. Pat. No. 7,267,620 It may have an outer metal cap that forms the outer striking surface 4512. , the face insert 4510 is incorporated herein by reference in its entirety. The ferroelectric material described in U.S. Patent No. 8,682,434, issued on January 14, 2014, It may be a base insert.
[0274] An exemplary thickness range for the composite portion of the faceplate is 7.0 mm or less. In this embodiment, the thickness of the faceplate may range from 7.0 mm to 4.0 mm. In some embodiments, the thickness of the faceplate is 5.0 mm + / - 1.0 mm. In some embodiments, the thickness of the faceplate is 3. 0mm to 6.0mm, and 1.0mm to 4.0mm at the periphery of the face plate. In some embodiments, the thickness of the faceplate may be 4 0.0mm to 5.0mm, and 2.0mm to 3.0mm at the periphery of the face plate. The composite material desirably promotes efficient distribution of impact forces and overall durability. To achieve this, the slab is constructed to have a relatively consistent distribution of reinforcing fibers across its cross-section of thickness. In addition, the thickness of the face insert 4510 is Achieve different performance characteristics and / or improve durability of golf head 4500 For example, in some embodiments, the phase may be changed in a particular region to achieve a desired effect. The thickness of the plate is 3.0mm to 6.0mm in the center region and As another example, in some embodiments, In the embodiment, the thickness of the faceplate is 4.0 mm to 5.0 mm in the central region. The thickness may be 2.0 mm to 3.0 mm at the periphery of the face plate. The Sert 4510 is designed to meet the desired durability and overall performance of the 4500 club head. A plurality of strips of composite material are selectively placed in a predetermined manner into the composite laminate to produce the desired By forming a profile, the substrate can be formed having any of a variety of cross-sectional profiles. This may also be the case.
[0275] The face insert 4510 is attached to the face support 4524 of the club head body 4520. Attachment is accomplished by applying a suitable adhesive (typically an epoxy or film adhesive). All composite face plate and club head body joints To prevent peeling and delamination defects in the joints, the composite faceplate is The metal body may be recessed from the front surface or may be substantially flush with the front surface. Desirably, the face insert 4510 can be of composite construction. The ends of the reinforcing fibers in the element are recessed sufficiently so as not to be exposed.
[0276] The composite portion of the Face Insert 4510 is fabricated as a laminate of multiple prepreg plies. The plies are constructed with fiber reinforcement and resin to provide the desired durability and puffiness of the club head. The prepreg is selected for varying laminate thicknesses. Some of the lies are made of elongated strips of prepreg material arranged in one or more sets of strips. The strips in each set include trips, as described in more detail further below. The strips are then cross-lapped to add thickness to the composite laminate in the overlapping areas. The strips are preferably arranged in a pattern that spans the finished composite part. That is, the ends of the strip extend continuously along the periphery of the finished composite part. In this manner, the reinforcing fibers extending in the longitudinal direction of the strip are also bonded to the ends of the part. The periphery of the composite part may extend continuously across the finished part. Thus, during the curing process, the defects may be moved toward the peripheral sacrificial portion of the composite laminate. The sacrificial portion is then subjected to a test that has few or no defects. In addition, the free ends of the fibers can be removed to provide a clean finished part. away from the zone and on the periphery of the finished part, the durability of the finished part Improve.
[0277] In testing of certain club head constructions, a relatively low fiber-based average weight (FAW) was Composite parts formed with prepreg plies are designed to provide improved impact resistance in multiple regions, e.g., impact resistance, It has been found to provide superior performance, such as durability and overall club performance. AW is the weight of the fiber part of a given amount of prepreg (unit: g / m 2 ) 100g / m 2 More preferably, less than 70 g / m 2 FAW values below are particularly effective. A particularly suitable fibrous material for use in making the prepreg plies is carbon fiber. More than one type of fibrous material may be used. In some embodiments, 2 Exceeding Prepreg plies having a FAW value of 0.1 to 0.5 may be used.
[0278] In certain embodiments, multiple low FAW prepreg plies can be stacked together, It also has a relatively uniform distribution of fibers through the thickness of the lie. In contrast, comparable resins Lamination of prepreg materials with higher FAW content (R / C unit:%) The plies have significantly more resin-rich regions than the laminate plies of low FAW material, particularly adjacent In particular, the forces generated by the impact of a golf ball tend to cause the fibers to Since the orientation of the fibers in the fiber reinforcement is generally transverse to the orientation of the fibers in the fiber reinforcement, the resin-rich regions are tend to reduce the effectiveness of

The composite component 4600 has a front surface 4602 and a rear surface 4603. In this example, composite component 4600 has a generally convex shape. 4606. The central region 4606 has a greater thickness and a comparatively thicker portion extending around the periphery of the central region 4606. The central region 460 in the illustrated example has a peripheral region 4608 that has a relatively small thickness. 6 has its thickest part at a center point 4610 (FIG. 47) and extends from that point in all directions. A protrusion or pyramid on the rear surface 4604 that gradually tapers toward a peripheral region 4608. The center point 4610 is located at the center of the face insert (e.g., face insert 45 10) represents the approximate center of the "sweet spot" (optimum hitting zone), but the face-in The thicker central region 4606 is not necessarily at the geometric center of the face insert. Adding stiffness to the center area of the face insert (4606) results in more consistent deflection across the face insert. In certain embodiments, the central region 4606 is approximately 5 mm to approximately 7 mm thick. and peripheral region 4608 has a thickness of about 4 mm to about 5 mm.

A plurality of sets or unit groups 4622a to 4622k of leg plies and a strip One or more sets or unit groups 4624a of individual plies in the form of a ply 4646 For purposes of illustration, each set of one or more plies 4622a-4624g 2k can be called a composite "panel", and each set 4624a to 4624g is a strip of A cluster of trips can be called a "cluster" of trips. 624a to 624g are stacked between the panels 4622a to 4622k, and the composite components 4 600 in its central region 4606. 22a-4622k include one or more individual prepreg plies having a desired fiber orientation. The individual plies forming each panel 4622a-4622k are preferably smaller. The present invention provides a method for forming a cured laminate from which a composite component 4600 can be formed substantially free of defects. The cluster 46 of strips 4626 is of sufficient size and shape to form a 24a-4624g desirably promote adhesion between the multiple layers of prepreg material and composite To provide an effective distribution of fibers across the cross section of the Component 4600, two adjacent Each panel is individually positioned between adjacent panels and sandwiched between two adjacent panels (i.e., Panels 4622a-4622k are made up of clusters of strips 4624a-4624g. (separate each one).

Exemplary carbon fibers include carbon fibers that have a tensile elastic modulus of 234 Gpa (34 Msi). "34-700" carbon fiber with high thermal conductivity and tensile strength of 4500Mpa (650Ksi) Fiber (available from Grafil, Sacramento, Calif.) may be used. Another Grafil fiber has a tensile modulus of 240 Gpa (35 Msi) and a tensile modulus of 4900 Mpa The preferred epoxy is "TR50S" carbon fiber, which has a tensile strength of 710 ksi. The resins are types "301" and "350" (Newport Adhesives and (Available from Epoxy Composites, Irvine, CA). The quantity (R / C) is 40%.
[0284] FIG. 51 is an exploded view of the first panel 4622a. For ease of reference, the lines (4 The fiber orientation (indicated by 640) is the direction from the horizontal axis of the face of the club head to the ply. The measurement is taken to a line substantially parallel to the fibers in the sample. Panel 4622a in FIG. 1 has a first ply 4628 with fibers oriented at +45 degrees. a, second ply 4628b with fibers oriented at 0 degrees, and b with fibers oriented at -45 degrees and a fourth ply 4628c having fibers oriented at 90 degrees. Therefore, the panel 4622a of the plies 4628a to 4628d includes plies 4628a to 4628d. In some embodiments, the remaining panels 4 622b to 4622k have the same number of prepreg plies and fiber orientation as panel 4622a. In some embodiments, the remaining panels 4622b-4622k may include panels 4 622a may have a different number of prepreg plies and / or fiber orientation.

Outer fiberglass ply 4650, single adjacent to 11th and last panel 4622k Carbon fiber ply 4652 and the innermost glass fiber ply adjacent to the single ply 4652 In some embodiments, the single ply 4652 may include a 90 degree In some embodiments, the fiberglass plies 4650, 4654 may have a fiber orientation of may have fibers oriented at 0 degrees and 90 degrees. The cured laminate 4620 is then subjected to a surface finishing process, such as sandblasting, to remove the part. It essentially serves as a sacrificial layer to protect the carbon fiber plies when smoothing the outer surface of the The fiberglass plies 4650 / 4654 can be referred to as the scrim layer.
[0286] FIG. 52 shows elongated plates arranged relative to one another such that the clusters have variable thickness. FIG. 4 is a close-up plan view of a first cluster 4624a of repreg strips. The cluster 4624a in the figure includes a first strip 4626a, a second strip 46 26b, third strip 4626c, fourth strip 4626d, fifth strip 4626e, a sixth strip 4626f, and a seventh strip 4626g. The strips are spaced apart sufficiently so that the strips overlap to define an overlap region 4660. The strips are stacked in a square pattern, with the end of each strip at an angle to the adjacent end of another strip. Thus, cluster 4624a is at the end of a strip. Each strip is preferably made from a large laminate. Extending continuously across the composite component 4600 to be cut or otherwise machined. The strips may have the same or different lengths and widths, although the strips are long enough to accommodate The length and width can vary depending on the desired overall shape of the composite component 4600. can be done.
[0287] The strips 4626a-4626g may be of equal length, and the cluster 462 4a may be positioned so that the geometric center point 4662 corresponds to the center of each strip. In some embodiments, the first three strips 4626a-4626c are The strip may have a width W1 that is greater than the width W2 of the strips 56d to 56g. The horizontal edge of strip 4626b and the adjacent edges of strips 4626a and 4626c The angle α between the edge of strip 4626b and the edges of strips 4626d and 4626g and the angle μ between the edge of strip 4626b and the nearest edge of strip 46 26e and 4626f define an angle θ between the nearest edges of the two. The width W1 can be about 20 mm, and the width W2 can be about 15 mm, The angle α can be about 24 degrees, the angle μ can be about 54 degrees, and the angle θ can be , can be about 78 degrees.
[0288] Referring again to FIG. 50, each of the clusters 4624a to 4624g is preferably a class The ends of each strip in the cluster must be aligned with the ends of the strips in the adjacent cluster. To avoid this, the clusters are rotated slightly or offset at an angle to adjacent clusters. In this way, the clusters are distributed in the peripheral region 4608 of the composite component 4600. The laminate 4620 is arranged relative to one another to provide a substantially uniform thickness. In some embodiments, the first cluster 4624a has an orientation of -18 degrees. This is because the "upper" edge of the second strip 4626b may be aligned with the adjacent unit group.
