Although the shells made of such materials and structures have certain firmness, they have poor impact resistance , when an accident occurs, the shell is easy to break and break, so its safety is difficult to be guaranteed, especially for RVs, because outdoor life is driven on country roads, beaches, Gobi, and ice and snow roads, often experiencing typhoons, severe cold, In severe heat, etc., not only its safety is more important, but also it needs to have good flame retardancy and thermal insulation. Later, although some shells made of composite materials appeared in the prior art, their performance indicators are still very low. , it is difficult to achieve comprehensive properties such as high safety, high flame retardancy, high thermal insulation, and even light weight.

Epoxy resin composite material layer 3 outside the strength glass fiber cloth layer 2, glass fiber mat 4 outside the epoxy resin composite layer 3, resin gel coat layer 5 outside the glass fiber mat 4, and resin gel coat outer coating Overlaid at least one layer of paint layer 6.
进一步地，所说的高强度玻璃纤维布层3优选地设置为三层，所说的刷漆层6包括树脂胶衣层外涂覆的抗紫外线漆以及抗紫外线漆外涂覆的双组份汽车表面漆，所说的龙骨1由两层玻璃纤维布层以及玻璃纤维面毡和玻璃纤维面毡外的树脂胶衣层构成，进一步提高了其优良的特性。Further, said high-strength fiberglass cloth layer 3 is preferably set to three layers, and said paint layer 6 includes the anti-ultraviolet paint coated on the outside of the resin gel coat layer and the two-component coating on the outside of the anti-ultraviolet paint. Automotive surface paint, said keel 1 is made of two layers of glass fiber cloth layers, glass fiber facing mat and resin gel coat layer outside the glass fiber facing felt, which further improves its excellent characteristics.
经过试验验证，采用本发明制成的蜂窝状环氧树脂复合材料与龙骨组成一体化全承载车身，遇到外力冲击或挤压时，回弹力高，变形小，不易破碎，产生的有效空间能够更有效的保护生命安全。It has been verified by experiments that the honeycomb epoxy resin composite material made by the present invention and the keel form an integrated full load-carrying vehicle body. When encountering external impact or extrusion, it has high resilience, small deformation, and is not easy to break, and the effective space produced can be More effective protection of life safety.
