Example Embodiment

[0032] Example 1

[0033] A car roof, which is made of a composite material composed of two natural fibers of ramie and jute and a resin, and the natural fiber accounts for 35% of the composite material by mass. In order to ensure the strength of the natural fiber, this embodiment The ramie and jute used are the plain weave ramie cloth produced by Jiangxi Jingzhu Hemp Industry Co., Ltd. and the jute cloth produced by Zhejiang Hongcheng Textile Finishing Co., Ltd. (that is, the technical scheme of this embodiment is participated in the form of cloth), of which the plain weave ramie cloth The mass percentage of the entire composite material is 15%, and the mass percentage of the jute cloth is 20%.

[0034] The selected resin can be unsaturated polyester resin (UP), epoxy resin, polyethylene resin (PP), polylactic acid resin (PLA), but the present invention finds that the epoxy-modified vinyl resin used in this embodiment Compared with unsaturated polyester resin and epoxy resin, the me

Abstract

The invention belongs to the technical field of materials and relates to a car part manufactured by natural fiber material, in particular to a car roof and a manufacturing method. Since the prior carroof is made of metal alloy and a complex structure can not be formed by metal stamping, dozens of or even hundreds of parts need manufacturing, resulting of great time and labor waste, In order to solve the problem of the prior car roof, the car roof provided by the invention is made of composite material comprising any two natural fibers in sisal hemp, ramie, jute and red ramie as well as resin,wherein the natural fibers is 30-40 percent by mass of the composite material. The car roof not only can effectively solve the technical problem, but also has the advantages of light weight, high strength, corrosion resistance, low cost and environment protection.
