Abstract
Description
Technical Field
[0001] This utility model relates to the field of helmets, specifically to a carbon fiber fabric with an airplane-pattern design for helmets. Background Technology
[0002] As an essential piece of equipment in sports such as cycling and motorcycling, as well as in the field of safety protection, the core function of helmets is to provide effective protection for the user's head. With the advancement of technology and the improvement of people's safety awareness, the design and manufacturing of helmets are constantly evolving, striving to meet the diverse needs of lightweight, comfort, and aesthetics while ensuring safety.
[0003] Currently, in bicycles and motorcycles, helmet shells are generally made of carbon fiber through stamping and heat curing, resulting in helmet shells that combine high strength and lightweight. However, despite the excellent performance of carbon fiber helmets, existing carbon fiber helmets, made solely of carbon fiber, present the following technical challenges in practical use:
[0004] First, pure carbon fiber products have certain limitations in impact resistance. When a helmet is subjected to a large external impact, pure carbon fiber may easily break due to its lack of sufficient toughness, thus reducing the overall protective effect of the helmet. Second, the patterns formed by pure carbon fiber products are mostly plain or diagonal weaves, which are quite common. This limits the appearance design of helmets to some extent and cannot meet consumers' strong demand for personalized and fashionable appearances.
[0005] In summary, it is necessary to develop a carbon fiber fabric with an aircraft-like pattern for helmets to improve the impact resistance and aesthetics of the carbon fiber fabric. Utility Model Content

[0018] Further configuration: the aforementioned carbon fiber base layer includes a positive 45-degree carbon fiber layer and a negative 45-degree carbon fiber layer, which are bonded together.
[0019] Further, the mass per unit area of the aforementioned aircraft-patterned carbon fiber used in the helmet is 330–370 g / m².

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] A type of helmet-grade carbon fiber with an airplane-like pattern is used to address the issue of how to improve the impact resistance and aesthetics of carbon fiber.
[0032] See Figure 1 As shown, Figure 1The image shown is a cross-sectional view of the aircraft-patterned carbon fiber fabric for helmets in this embodiment. The aircraft-patterned carbon fiber fabric for helmets includes an aircraft-patterned layer 1 and a carbon fiber base layer 2.
[0033] The aircraft-patterned layer 1 is formed by cross-weaving of carbon fiber warp yarns 11 and metal fiber weft yarns 12 of different colors, creating a structure with an aircraft-shaped pattern.
[0034] The carbon fiber base layer 2 is fixed to the inner side of the aircraft texture layer 1 by resin bonding, and the carbon fiber base layer 2 is configured as the innermost layer of the helmet shell.
[0035] The helmet using the above technical solution uses carbon fiber fabric with an airplane pattern to weave an airplane pattern layer 1 through carbon fiber warp yarns 11 and metal fiber weft yarns 12 of different colors. The airplane pattern layer 1 has excellent impact resistance. When combined with the carbon fiber base layer 2, it can effectively improve the impact resistance of the carbon fabric, thereby enhancing the structural strength and impact resistance of the helmet. In addition, the airplane pattern of the airplane pattern layer 1 is novel and can also make the helmet shell aesthetically pleasing, meeting consumers' demand for personalized and fashionable appearance.
[0036] See Figure 2 As shown, Figure 2 This is a plan view of the first weave structure of the aircraft texture layer in one embodiment. In one implementation of the aircraft texture layer 1, the carbon fiber warp yarns 11 include a first warp yarn 111, a second warp yarn 112, a third warp yarn 113, a fourth warp yarn 114, and a fifth warp yarn 115 arranged sequentially. Based on the metal fiber weft yarn 12, the floating / sinking state of the first warp yarn 111 is: float-float-float-float; the floating / sinking states of the second warp yarn 112 and the third warp yarn 113 are both: float-float-float-float; the floating / sinking state of the fourth warp yarn 114 is: float-sink-float-float; and the floating / sinking state of the fifth warp yarn 115 is: float-sink-sink-float-float. The description of these floating / sinking states (such as "float" and "sink") is based on the relative positions of the warp and weft yarns during the weaving process. "Float" indicates that the warp yarn is above the weft yarn, and "sink" indicates that the warp yarn is below the weft yarn. The description of the floating / sinking states below is similar and will not be repeated. Thus, by interlacing the carbon fiber warp yarn 11 and the metal fiber weft yarn 12 according to this floating and sinking pattern, a structure with an airplane-shaped texture can be woven.
[0037] See Figure 3 As shown, Figure 3This is a plan view of the second weaving structure of the aircraft texture layer in the embodiment. In one embodiment of the aircraft texture layer 1, the carbon fiber warp yarn 11 includes a first warp yarn 111, a second warp yarn 112, a third warp yarn 113, a fourth warp yarn 114, a fifth warp yarn 115, a sixth warp yarn 116, a seventh warp yarn 117, and an eighth warp yarn 118. Based on the metal fiber weft yarn 12, the sinking and floating states of the first warp yarn 111 are as follows: sink-float-sink-float-float-float-float-float-sink-sink-float-float-float-sink ... The sinking and floating states of the fifth warp 115 are as follows: sinking-sinking-floating-floating-sinking ... Thus, by interlacing the carbon fiber warp yarn 11 and the metal fiber weft yarn 12 according to this floating and sinking rule, a structure with an airplane-shaped pattern can also be woven. Moreover, the airplane-shaped pattern woven according to this floating and sinking rule is arranged in an interlaced and denser manner, and the impact resistance of the airplane pattern layer 1 is also better.
[0038] In addition to the two weaving structures mentioned above, other floating and sinking patterns can also be used for the airplane-shaped weave layer 1, as long as they can form an airplane-shaped pattern.
[0039] See Figure 1 As shown, based on any of the above embodiments, the helmet-grade carbon fiber fabric with an aircraft pattern further includes a transparent abrasion-resistant layer 3. The transparent abrasion-resistant layer 3 is bonded to the outside of the aircraft pattern layer 1 via resin and is configured as the outermost layer of the helmet shell. The transparent abrasion-resistant layer 3 is any one of a polypropylene layer, a transparent polyamide resin layer, or a transparent PVC layer. Thus, the transparent abrasion-resistant layer 3 can improve the abrasion resistance and impact resistance of the carbon fiber fabric without affecting the pattern presentation of the aircraft pattern layer 1. It also makes the outer surface of the helmet appear glossy and smooth, enhancing the helmet's aesthetic appeal.
[0040] See Figures 1 to 3As shown, in one embodiment of the metal fiber, the metal fiber is any one of stainless steel fiber, titanium fiber, and alloy fiber. Thus, stainless steel fiber, titanium fiber, and alloy fiber are all high-strength, corrosion-resistant metallic materials. The metal fiber produced in this way can enhance the wear resistance and durability of the aircraft texture layer 1, thereby enhancing the wear resistance and durability of the carbon cloth.
[0041] Alternatively, the aforementioned metal fiber weft yarn 12 can also be made of metal fibers with a significantly different color from the carbon fiber warp yarn 11. This would make the woven airplane-shaped pattern novel and eye-catching, giving the helmet shell a good appearance quality and meeting consumers' aesthetic needs.
[0042] See Figure 1 As shown, in one embodiment of the carbon fiber base layer 2, the carbon fiber base layer 2 includes a positive 45-degree carbon fiber layer 21 and a negative 45-degree carbon fiber layer 22, which are bonded together with resin. Thus, the aircraft-patterned carbon fiber fabric for helmets, through the positive 45-degree carbon fiber layer 21 and the negative 45-degree carbon fiber layer 22, can improve mechanical properties such as axial tensile strength and radial tensile strength, thereby ensuring the structural strength of the aircraft-patterned carbon fiber fabric for helmets.
[0043] The resins used for bonding can be any one of phenolic resin, epoxy resin, or unsaturated polyester resin.
[0044] Based on any of the above embodiments, the area mass of the carbon fiber fabric used in this helmet, which mimics the texture of aircraft patterns, is 330–370 g / m². This ensures that the strength meets regulatory requirements while also achieving the goal of lightweight design.
[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
