The invention particularly relates to an automobile bumper prepared from a thermoplastic composite material, and provides an automobile bumper made of a composite material, wherein the composite material takes a thermoplastic resin as a matrix and is reinforced with carbon fiber. The automobile bumper is provided with a front panel, a cross beam, a supporting framework and a foam material, whereinthe front panel, the cross beam, the supporting framework and the foam material are made of an impact-resistant composite material, a rigid composite material and an energy-absorbing material respectively. According to the invention, the impact resistance and the deformation resistance of the bumper are effectively improved through the design of different carbon fibers and the design of the wovenstructure of the front panel and the cross beam, the impact energy absorption efficiency of the bumper is effectively improved through the middle three-dimensional composite framework energy absorption sandwich layer, and the overall impact resistance safety is guaranteed.

    本发明具体涉及一种热塑性复合材料制备的汽车保险杠。本发明提供了一种采用热塑性树脂作为基体、碳纤维增强的复合材料的汽车保险杠。该汽车保险杠具有前置面板、横梁及支撑骨架及泡沫材料分别采用耐冲击复合材料、刚性复合材料及吸能材料制成。其中前置面板和横梁通过不同碳纤维的设计和编织结构设计有效提高了保险杠的耐冲击和抵抗变形能力,中间三维复合材料骨架吸能夹芯层有效提高了保险杠的冲击能吸收效率,保证整体的耐冲击安全性。
