The invention relates to a carbon fiber composite material automobile roof middle cross beam which is prepared from a carbon fiber reinforced composite material with a carbon fiber laying structure; carbon fiber is taken as a reinforcing material, the longitudinal direction of the cross beam is a 0-degree direction, and the transverse direction of the cross beam is a 90-degree direction; carbon fibers are sequentially laid according to the sequence of a degrees, -a degrees, 0 degree, 90 degrees, 90 degrees, 0 degree, -a degrees and a degrees from top to bottom, eight layers are laid in total,mold pressing one-time forming is conducted with resin as a binder, and compared with a traditional metal cross beam, the obtained cross beam is light in weight, high in specific strength and higher in designability; the cross section of the beam adopts an M-shaped structure to ensure the overall rigidity of the beam; a compression molding method is adopted, raw material losses are small, the moldmanufacturing cost is low, the method is suitable for large-batch production, the application prospect on various automobile body structural parts is wider, the performance is more advanced, and higher engineering application value and sustainable development are achieved.
本发明涉及一种碳纤维复合材料汽车顶盖中横梁,选用碳纤维铺层结构的碳纤维增强复合材料,以碳纤维为增强材料,以所述横梁的纵向为0°方向、横向为90°方向,将碳纤维从上到下依次按照a°,‑a°,0°,90°,90°,0°,‑a°,a°的顺序进行铺层,共铺设8层,以树脂为粘结剂进行模压一次成型,得到的横梁按照相较于传统金属横梁,重量轻,比强度高,可设计性更强;横梁截面采用M型结构,保证横梁整体刚性;采用模压成型方法,原料损失少,模具制造费用较低,适合大批量生产,在各类汽车车身结构件上应用前景更广,性能更先进,具有更高的工程应用价值和可持续发展性。
