Description

[Technical Field]

[0001] FIELD OF THE DISCLOSURE This disclosure relates generally to composite structures, and more particularly to apparatus and methods for forming composite materials. Even more particularly, this application relates to apparatus and methods for forming multi-ply structures and trimming multi-ply structures. [Background technology]

[0002] Composite structures are widely used as high-strength, lightweight alternatives to metals, such as in aerospace applications. A composite structure (e.g., a composite laminate) is formed by one or more composite layers (also called plies or laminations). Each composite layer includes a reinforcement material and a matrix material. The reinforcement material may include fibers. The fibers may be oriented in a single direction (e.g., unidirectional) or in two directions (e.g., bidirectional). The matrix material may include a resin.

[0003] Fiber bundles may be laid up in layers to form a reinforced layup, such as a preform. Resin is injected into the spaces defined between the fiber bundles of the preform to form a consolidated preform. The preform may be called a wet preform (or prepreg) if the fiber bundles are pre-impregnated with resin, or a dry preform if no resin is present. The consolidated preform is partially or fully cured to form a composite structure. One example of a composite structure is a carbon fiber reinforced polymer.

[0004] It is desirable to trim or cut the layers as they are laid up to form a preform. It is also desirable to trim or cut the plies as they are laid up to form a preform through an automated process and / or automated system. Existing automated processes and / or systems only address trimming a single ply at a time or trimming the entire thickness of a laminate. Currently, there are no solutions that address differentially trimming components of a multi-ply structure simultaneously.

[0005] Accordingly, those skilled in the art continue to conduct research and development efforts in the area of ​​automated methods and systems for trimming multi-ply structures. Summary of the Invention

[0006] One example of the disclosed automated method for trimming a multi-ply structure having at least a first ply and a second ply includes applying the first ply onto a platen, positioning a cutting plate over a protective portion of the first ply, applying the second ply onto the platen such that the cutting plate is between the protective portion of the first ply and an upper portion of the second ply, and cutting the upper portion of the second ply.

[0007] One example of a disclosed automated method for trimming a multi-ply structure having at least a first ply comprising a first composite material and a second ply comprising a second composite material includes positioning the membrane on a platen, positioning a cutting plate over a protected portion of the membrane, applying the first ply over the platen with a laminator so that the cutting plate is between the protected portion of the membrane and the upper portion of the first ply, cutting the upper portion of the first ply, positioning the cutting plate over the protected portion of the first ply, applying a second ply over the platen with the laminator so that the cutting plate is between the protected portion of the first ply and the upper portion of the second ply, and cutting the upper portion of the second ply.

[0008] One example of a disclosed automated multi-ply structure trimming system includes a platen, a laminator movable relative to the platen to apply at least a first ply and a second ply onto the platen, a cutting plate movable relative to the platen and positionable between the first ply and the second ply, and a cutting tool movable relative to the platen to cut the second ply.

[0011] The following detailed description refers to the accompanying drawings, which illustrate certain non-limiting examples of the present invention. Other examples having different structures and processes do not depart from the scope of the present disclosure. Similar reference numbers may refer to the same elements or components in various drawings.

[0012] 1-10 show a first non-limiting example of an automated multi-ply structural trimming system 15. The automated multi-ply structural trimming system 15 includes a platen 140, a laminator 170 movable or stationary relative to the platen 140 for applying at least a first ply 120 (see FIG. 3) and a second ply 130 (see FIG. 8) onto the platen 140, a cutting plate 152 (see FIG. 8) movable relative to the platen 140 and positionable between the first ply 120 and the second ply 130, and a cutting tool 160 (see FIG. 4) movable relative to the platen 140 for cutting the second ply 130.

[0013] In some examples, the platen 140 includes any shape or geometry selected with good engineering judgment. In some examples, the platen 140 is planar or substantially planar. In other acceptable examples, the platen 140 is not planar. In some acceptable examples, the platen 140 is contoured. In some examples, the platen 140 is movable relative to one or more other components described for use in the methods and systems described herein. In some examples, the platen 140 is configured to be movable by some automated actuator. As described further below, in some examples, the platen 140 is movable relative to one or more workstations 10.

[0014] In some examples, applying the first ply (120) over the platen (140) is performed such that the first ply (120) is in direct contact with the platen (140). As an acceptable alternative, applying the first ply (120) over the platen (140) is performed such that the first ply (120) does not directly contact the platen (140), but rather indirectly contacts the platen (140) via a membrane (142) or other intermediate material. The membrane (142) will be discussed further below. In some examples, applying the second ply (130) over the platen (140) is performed such that at least a portion of the second ply (130) is in direct contact with the platen (140). As an acceptable alternative, the second ply (130) is applied onto the platen (140) so that at least a portion of the second ply (130) does not directly contact the platen (140), but rather indirectly contacts the platen (140) via the membrane (142), the first ply (120), or other intermediate material.

[0015] 12A-12B, in some non-limiting examples, the first ply (120) and the second ply (130) are staggered or positioned such that the second ply (130) does not completely overlap the first ply (120) at all locations. In some non-limiting examples, as shown in FIGS. 12A-12B, the first ply (120) at least partially overlaps the membrane (142) on the platen (140), and the second ply (130) at least partially overlaps the first ply (120) and partially overlaps the platen (140) and / or the membrane (142) on the platen (140).

[0016] The laminator (170) may include any type of laminator (170) selected with good engineering judgment. Some optional examples include multiple laminators (170). The laminator (170) may be movable or stationary relative to one or more other components described for use in the methods and systems described herein. In some examples, the laminator (170) may be configured to be movable by some automated actuator (162). In some examples, the laminator (170) may be movable relative to the platen (140) and cutting plate (152). In some optional examples, the laminator (170) may be stationary relative to the platen (140) and cutting plate (152). In some example options, there are multiple laminators (170) with a stationary 0-degree laminator (170), a movable platen (140) relative to the 0-degree laminator (170) to dispense material onto the first ply (120) or the second ply (130), a movable 45-degree laminator (170), or a movable 90-degree laminator (170), or both a movable 45-degree laminator (170) and a movable 90-degree laminator (170).

[0017] The cutting plates (152) are selectively movable and positionable to prevent cutting of a subcomponent or material (e.g., the platen (140), the film (142), the first ply (120), or the second ply (130)). The system, in some non-limiting examples, includes one, two, three, or more cutting plates (152). The cutting plates (152) are configured to be movable relative to the platen (140) about an axis of rotation (156). In other non-limiting examples, the cutting plates (152) are configured to be movable relative to the platen (140) by translation or a combination of translation and rotation. In some non-limiting examples, as shown in FIG. 10, the axis of rotation (156) is perpendicular to at least one imaginary vector (12) that is normal to the cutting plates (152). In some non-limiting examples, the rotation axis (156) is parallel to at least one imaginary vector that is perpendicular to the cutting plate (152). In some examples, the rotation axis (156) is fixed in space relative to the cutting plate (152), but this is not true in all examples.

[0018] Continuing with reference to FIGS. 1-10 , in some examples, the cutting tool (160) is movable relative to the platen (140) and can cut the first ply (120), or the second ply (130), or the second ply (130) and the first ply (120), or some other set of plies. In some examples, the cutting tool (160) cannot cut the cutting plate (152). In some examples, the cutting tool (160) can only slightly or slowly cut the cutting plate (152), so that the cutting plate (152) is only slightly cut by any given cutting action and can withstand many cutting actions. In some examples, the cutting plate (152) can withstand at least two cutting actions. In some examples, the cutting tool (160) cannot cut the second cutting plate (182). In some examples, the cutting tool (160) may be able to cut the second cutting plate (182) only slightly or slowly, such that the second cutting plate (182) is only slightly cut by any given cutting operation and may be able to withstand many cutting operations. In some examples, the second cutting plate (182) may be able to withstand at least two cutting operations. In some examples, during a cutting operation, the cutting tool (160) will contact the cutting plate and completely cut through the composite material in a single pass. As shown in FIGS. 11A-11C , in some examples, the cutting tool (160) will include one or more of an ultrasonic knife (163), a mechanical knife (165), and a wheel cutter (167). In other non-limiting examples, the cutting tool (160) is some other type of tool that does not include an ultrasonic knife (163), a mechanical knife (165), or a wheel cutter (167). In some instances, the cutting tool (160) is operated to cut portions of the material above the cutting plate (152), each of these latter portions being referred to as an upper portion, while the protective portion (20) below the cutting plate (152) remains uncut.

[0019] Continuing with reference to FIGS. 1-10 , in some examples, the system 15 optionally includes a film 142 positioned on the platen 140. In such examples, the platen 140 supports the film 142 positioned on the platen 140. In other non-limiting examples, the system 15 does not include a film 142 positioned on the platen 140, or the platen 140 does not support the film 142 positioned on the platen 140. In some examples, the film 142 directly contacts the platen 140. In some examples, the film 142 indirectly contacts the platen 140. In some examples, the film 142 is a release paper or some other material adapted to facilitate removal of the first ply 120 or another ply or material from the platen 140.

[0020] Continuing with reference to FIGS. 1-10 , in some examples, the system (15) further includes a scrap bin (16) (see FIG. 5 ) positioned to receive scrap (134) generated from the first ply (120) and / or the second ply (130). In some examples, the system (15) includes no scrap bin (16), one scrap bin (16), two scrap bins (16), or more scrap bins (16). The scrap bin (16) is adapted and / or positioned to receive first scrap (124) removed from the first ply (120), to receive second scrap (134) removed from the second ply (130), to receive scrap removed from another ply, or a combination thereof.

[0021] Continuing with reference to FIGS. 1-10 , in some examples, the system (15) further includes one or more automated actuators. In some examples, the system (15) includes an automated actuator (162) operatively associated with the platen (140) and adapted to move the platen (140), an automated actuator (162) operatively associated with the laminator (170) and adapted to move the laminator (170), an automated actuator (162A) operatively associated with the cutting plate (152) and adapted to move the cutting plate (152), or any combination thereof. In some examples, the system (15) includes a cutting tool (160) operatively associated with an automated actuator (162B), such that the automated actuator (162B) is adapted to move the cutting tool (160) and perform the cutting operation. In some embodiments, the actuator (162) Electromagnetic, pneumatic, hydraulic, or other selection based on good engineering judgment.

[0022] 11A-11C show different non-limiting examples of cutting tools.

[0023] Figures 12A-12B show different ply placement patterns and how they are trimmed.

[0024] 13-23 show a second non-limiting example of an automated multi-ply structural trimming system (15). The automated multi-ply structure trimming system (15) includes a platen (140), a laminator (170) movable or stationary relative to the platen (140) for applying at least a first ply (120) (see FIG. 15) and a second ply (130) (see FIG. 8) onto the platen (140), a cutting plate (152) (see FIG. 16) movable relative to the platen (140) and positionable between the first ply (120) and the second ply (130), a second cutting plate (182) (see FIG. 16) movable relative to the platen (140) and positionable between the first ply (120) and the second ply (130), and a first cutting tool (160) and a second cutting tool (169), each movable relative to the platen (140), for cutting the second ply (130).

[0025] In some aspects of the second non-limiting example, the platen (140) includes any form or geometry selected with good engineering judgment. In some examples, the platen (140) is planar or substantially planar. In other acceptable examples, the platen (140) is not planar. In some acceptable examples, the platen (140) is contoured. In some examples, the platen (140) is movable relative to one or more other components described for use in the methods and systems described herein. In some examples, the platen (140) is configured to be movable by some automated actuator (162). As described further below, in some examples, the platen (140) is movable relative to one or more workstations (10).

[0026] In some aspects of the second non-limiting example, applying the first ply (120) onto the platen (140) is performed such that the first ply (120) is in direct contact with the platen (140). As an acceptable alternative, applying the first ply (120) onto the platen (140) is performed such that the first ply (120) does not directly contact the platen (140), but rather indirectly contacts the platen (140) via a membrane (142) or other intermediate material. The membrane (142) will be discussed further below. In some examples, applying the second ply (130) onto the platen (140) is performed such that at least a portion of the second ply (130) is in direct contact with the platen (140). As an acceptable alternative, the second ply (130) is applied onto the platen (140) so that at least a portion of the second ply (130) does not directly contact the platen (140), but rather indirectly contacts the platen (140) via the membrane (142), the first ply (120), or other intermediate material.

[0027] In some embodiments of the second non-limiting example, the laminator (170) includes any type of laminator (170) selected with good engineering judgment. Some optional examples include multiple laminators (170). The laminator (170) is movable or stationary relative to one or more other components described for use in the methods and systems described herein. In some examples, the laminator (170) is configured to be movable by some automated actuator (162). In some examples, the laminator (170) is movable relative to the platen (140), the cutting plate (152), and the second cutting plate (182). In some optional examples, the laminator (170) is stationary relative to the platen (140), the cutting plate (152), and the second cutting plate (182). In some example options, there are multiple laminators (170) with a stationary 0-degree laminator (170), a movable platen (140) relative to the 0-degree laminator (170) to dispense material onto the first ply (120) or the second ply (130), a movable 45-degree laminator (170), or a movable 90-degree laminator (170), or both a movable 45-degree laminator (170) and a movable 90-degree laminator (170).

[0028] In some aspects of the second non-limiting example, the cutting plate (152) is selectively movable and positionable to prevent cutting of a subcomponent or material (e.g., the platen (140), the film (142), the first ply (120), or the second ply (130)). The cutting plate (152) is configured to be movable relative to the platen (140) about a rotation axis (156) and to be movable relative to the platen (140) by translational motion. As shown in FIGS. 18A-18C, the rotation axis (156) is perpendicular to at least one imaginary vector (12) perpendicular to the cutting plate (152). In some non-limiting examples, the rotation axis (156) is parallel to at least one imaginary vector perpendicular to the cutting plate (152). In some examples, the rotation axis (156) is fixed in space relative to the cutting plate (152), but this is not true in all examples.

[0029] In some instances of the second non-limiting example, the second cutting plate (182) is selectively movable and positionable to prevent cutting of a subcomponent or material (e.g., the platen (140), the membrane (142), the first ply (120), or the second ply (130)). The second cutting plate (182) is configured to be movable relative to the platen (140) about a second axis of rotation (186) and to be movable translationally relative to the platen (140). As shown in FIGS. 18A-18C, the second axis of rotation (186) is perpendicular to at least one imaginary vector (12) perpendicular to the second cutting plate (182). In some non-limiting examples, the second axis of rotation (186) is parallel to at least one imaginary vector perpendicular to the second cutting plate (182). In some instances, the second axle (186) is fixed in space relative to the second cutting plate (182), but this is not the case in all instances.

[0030] Continuing with reference to Figures 13-23, in some examples, the cutting tool (160) and the second cutting tool (169) are each movable relative to the platen (140) and each can cut the first ply (120), or the second ply (130), or the second ply (130) and the first ply (120), or some other pair of plies. In some examples, the cutting tool (160) is unable to cut the cutting plate (152). In some examples, the cutting tool (160) and the second cutting tool (169) are each able to only slightly or slowly cut either the cutting plate (152) or the second cutting plate (182), so that the cutting plate (152) or the second cutting plate (182) will only be slightly cut by any given cutting action and will be able to withstand many cutting actions. In some examples, the cutting plate (152) and the second cutting plate (182) may each withstand at least two cutting operations. In some examples, during a cutting operation, the cutting tool (160) contacts the cutting plate (152) and completely cuts through the composite material in a single pass. In some examples, during a cutting operation, the second cutting tool (169) contacts the second cutting plate (182) and completely cuts through the composite material in a single pass. In some examples, the cutting tool (160) is operated to cut a portion of the material above the cutting plate (152), each of these latter portions being referred to as an upper portion, while the protective portion (20) below the cutting plate (152) remains uncut. In some instances, the second cutting tool (169) is operated to cut portions of the material above the second cutting plate (182), each of these latter portions being referred to as an upper portion, while the protective portion (20) below the second cutting plate (182) remains uncut.

[0031] Continuing with reference to Figures 13-23, and particularly Figures 14 and 15, in some examples, the system (15) optionally includes a membrane (142) positioned on the platen (140). In such examples, the platen (140) supports the membrane (142) positioned on the platen (140). In other non-limiting examples, the system (15) does not include a membrane (142) positioned on the platen (140), or the platen (140) does not support the membrane (142) positioned on the platen (140). In some examples, the membrane (142) directly contacts the platen (140). In some examples, the membrane (142) indirectly contacts the platen (140). In some examples, the membrane (142) is a release paper or some other material adapted to facilitate removal of the first ply (120) or another ply or material from the platen (140).

[0032] Continuing with reference to Figures 13-23, and particularly Figure 22, in some examples, the system (15) further includes a scrap bin (16) positioned to receive first scrap (124) generated from the first ply (120) and / or the second ply (130). In some examples, the system (15) includes no scrap bin (16), one scrap bin (16), two scrap bins (16), or more scrap bins (16). The scrap bin (16) is adapted and / or positioned to receive first scrap (124) removed from the first ply (120), to receive second scrap (134) removed from the second ply (130), to receive scrap removed from another ply, or a combination thereof.

[0033] Continuing with reference to Figures 13-23, in some examples, the system 15 further includes one or more automated actuators. In some examples, the system 15 includes an automated actuator 162 operatively associated with the platen 140 and adapted to move the platen 140, an automated actuator 162 operatively associated with the laminator 170 and adapted to move the laminator 170, an automated actuator 162A operatively associated with the cutting plate 152 and adapted to move the cutting plate 152, an automated actuator 162A operatively associated with the second cutting plate 182 and adapted to move the second cutting plate 182, or any combination thereof. In some examples, the system 15 includes a cutting tool 160 operatively associated with an automated actuator 162B, such that the automated actuator 162B is adapted to move the cutting tool 160 and perform a cutting operation. In some examples, the system 15 includes a second cutting tool 169 operatively associated with the automated actuator 162B, such that the automated actuator 162B is adapted to move the second cutting tool 169 and perform a cutting operation. In some examples, the automated actuator 162B includes a trim gantry 144 and a trim head 145. In some embodiments, the actuator 162B Electromagnetic, pneumatic, hydraulic, or other selection based on good engineering judgment.

[0034] In a second non-limiting example shown in FIG. 13-23, the system (15) further includes a second cutting plate (182) movable relative to the platen and positionable between the first ply (120) and the second ply (130). For example, FIG. 13-23 illustrates a second example of an automated multi-ply structural trimming system (15) including a first cutting plate (152) and a second cutting plate (182). As shown in FIG. 13-23, in some examples, the system (15) further includes a second cutting plate (182) movable relative to the platen (140) and positionable between the first ply (120) and the second ply (130). The second cutting plate (182) is movable relative to the platen (140) about an axis of rotation different from the axis of rotation (156). In some non-limiting examples, the second cutting plate (182) is movable relative to the platen (140) by translation or a combination of translation and rotation. In some non-limiting examples, the rotation axis of the second cutting plate (182) is perpendicular to at least one imaginary vector (12) perpendicular to the second cutting plate (182). In some non-limiting examples, the rotation axis of the second cutting plate (182) is parallel to at least one imaginary vector perpendicular to the second cutting plate (182). In some examples, the rotation axis of the second cutting plate (182) is fixed in space relative to the second cutting plate (182), but this is not true in all examples. A subcomponent or portion of material protected by the cutting plate (152), or the second cutting plate (182), or another cutting plate, is referred to herein as a protective portion (20).

[0035] Continuing with reference to Figures 13-23, and particularly Figures 18A-C, in a second non-limiting example, the first cutting plate (152) is adapted to rotate about an axis of rotation (156) and to translate either vertically or horizontally by sliding a slot (158) relative to the axis of rotation (156).
