The invention discloses an automobile composite pedestrian protection beam. The automobile composite pedestrian protection beam comprises a protection beam body formed through integrated compression molding, an energy absorption box used for absorbing impact force borne by the protection beam, and a rectangular aluminum sheet connected between the energy absorption box and the protection beam body, wherein the protection beam body is made of a glass fiber composite material, the surface of the protection beam body is reinforced by carbon fibers or aramid fibers to improve the strength of the protection beam, and the protection beam body and carbon fibers or aramid fibers are connected in an adhesive mode; the section of the protection beam is designed to be M-shaped, and continuous geometric reinforcing ribs are arranged on the inner side of the protection beam; and in order to be effectively connected with the energy absorption box, the two ends of the protection beam are each provided with a sunken cuboid groove, and the bottom surfaces of the grooves are connected with the energy absorption box through the aluminum sheets. The pedestrian protection beam is manufactured by adopting a compression molding process, the process is simple, and large-batch manufacturing can be realized; and the composite material is adopted for design, the dead weight is effectively reduced while the strength of the protection beam is guaranteed, and the lightweight design is achieved.

    本发明公开一种汽车复合材料行人保护梁,包括一体式模压成型的保护梁本体、用于吸收保护梁所受冲击力的吸能盒以及连接吸能盒与保护梁本体之间的长方形铝片。其中,保护梁本体采用玻璃纤维复合材料制成,表面再用碳纤或芳纶纤维进行补强,用于提高保证梁的强度,两者使用胶粘方式连接;保护梁的截面形状设计为M型,内侧设置有连续的几何型加强筋;为了与吸能盒进行有效连接,保护梁两端各有一个下沉的长方体凹槽,凹槽底面通过铝片与吸能盒连接。该行人保护梁采用模压成型工艺制成,工艺简单,可实现大批量制造;采用复合材料进行设计,在保证保护梁强度的同时有效减少自重,实现了轻量化设计。
