Composite wheel frame manufactured from single-warp weaving carbon fibers and manufacturing method thereof

Abstract

The invention relates to a composite wheel frame manufactured from single-warp weaving carbon fibers and a manufacturing method of the composite wheel frame, in particular to a composite wheel frame with light weight and high strength. The composite wheel frame is formed from a plurality of sheet carbon fiber cloths and a plurality of strip-like carbon fiber cloths by surrounding layer by layer, wherein the carbon fiber cloths are selected from single-warp woven carbon fiber cloth bodies; and the sheet carbon fiber cloths and the sheet carbon fiber cloths at adjacent layers are arranged at different included angles, so that the composite wheel frame is manufactured by soaking resin, heating and pressurizing. The composite wheel frame is designed with multiple layers and multiple angles, so that the composite wheel frame has the functions of continuity, integration and light weight, and can greatly save the materials and reduce working hours, and the strength of the composite wheel frame is improved.

Description

Technical field [0001] The present invention belongs to the preparation technology of a composite material wheel frame, and specifically refers to a multi-angle and continuous composite material wheel frame using uni-warp woven carbon fiber and a manufacturing method thereof, so as to improve the composite material wheel frame Strength, and save a lot of materials and man-hours. Background technique [0002] According to the development and diversification of material technology, the existing automobile wheel frame is formed of metal material. However, under the premise of emphasizing the weight reduction of the material, the above-mentioned metal material wheel frame cannot meet the requirements of light weight. In order to achieve the purpose of reducing weight, the improved wheel frame is made of composite materials with light weight and toughness that are laminated and wound outside the inner mold. The composite materials are selected from carbon fiber [Carbon Fiber] and glas...

Problems solved by technology

[0004] In the manufacturing method of the aforementioned existing composite material wheel frame, the biggest problem is that, since the surface of the wheel frame of the automobile has grooves for tire positioning and embedding, and at the same time, in order to improve the strength of the wheel frame to support the weight of the car, usually the wheel frame The cross-section has several ring-shaped ribs and slopes, rather than a smooth shape. Due to the lack of ductility of the UD carbon fiber cloth, if the UD carbon fiber cloth is continuously wrapped around the surface of the inner mold, it will be caused by these unevenness. Wrinkles occur, so it is necessary to use such as figure 2 The sheet-like UD carbon fiber cloth shown in the figure is processed by patching one by one to form a circle, and it is necessary to perform staggered and local reinforcement actions during the patching process, which not only increases the difficulty of manufacturing and wastes time, but also A lot of joining lines will be produced, so that the UD carbon fiber cloth cannot be wound continuously, causing its strength to weaken. In this way, the existing composite wheel frame may be cracked due to high-speed driving on uneven roads in actual use, affecting the driving safety
