The invention discloses a hybrid fiber composite material automobile bumper with a combined structure. The hybrid fiber composite material automobile bumper comprises a front impact-resistant composite material panel, a middle combined splicing rigid supporting layer and a rear high-rigidity composite material supporting plate, the front impact-resistant composite material panel is made of a high-strength carbon fiber mixed impact-resistant special fiber reinforced thermoplastic resin composite material; the middle combined and spliced rigid supporting layer comprises a plurality of U-shaped plates which are provided with opposite openings and are alternately buckled and spliced; the middle combined and spliced rigid supporting layer is formed by weaving and splicing U-shaped plates through hybrid carbon fibers and then forming a continuous body through thermoplastic resin; and the rear high-rigidity composite material supporting plate is made of a high-modulus carbon fiber two-dimensional braided structure reinforced thermoplastic resin composite material. By means of the structural design, light weight, impact resistance and deformation resistance of the bumper can be achieved at the same time, and wide application prospects are achieved.
本发明公开了一种组合结构混杂纤维复合材料汽车保险杠,其包括前置耐冲击复合材料面板、中间组合拼接刚性支撑层和后置高刚性复合材料支撑板;前置耐冲击复合材料面板的材质为高强度碳纤维混杂耐冲击特种纤维增强热塑性树脂复合材料;中间组合拼接刚性支撑层包括多个开口相反且交替扣合拼接的U型板;中间组合拼接刚性支撑层由U型板通过混杂碳纤维编织拼接,然后通过热塑性树脂形成连续体而得;后置高刚性复合材料支撑板的材质为高模量碳纤维二维编织结构增强热塑性树脂复合材料。本发明上述结构设计能够同时实现保险杠的轻量化、耐冲击和耐变形,具有广阔的应用前景。
