The invention belongs to the technical field of automobile body parts, and particularly relates to a composite material automobile body A column lower end reinforcing structure. Comprising a composite material structural body, the composite material structural body comprises a beam body, a containing cavity is formed in the beam body, and the beam body is made of a continuous fiber composite material; the rib bodies are of a latticed structure, are arranged on the two sides of the containing cavity, are connected with the beam body and are made of discontinuous fiber composite materials. The sealing edge is arranged around the edge of the beam body by a circle and is made of a discontinuous fiber composite material; the expansion body is made of a high-rigidity foaming material and is mounted on the composite material structure body; the problems that in the prior art, a car body A column reinforcing plate made of metal is not beneficial to the lightweight design of a car body, and structural crushing cannot be effectively avoided are solved.
本发明属于汽车车身零部件技术领域,尤其涉及一种复合材料车身A柱下端补强结构。包括复合材料结构体,所述复合材料结构体包括梁体,其内设有容置腔,由连续纤维复合材料制成;筋体为网格状结构,设于所述容置腔两侧且与所述梁体连接,由非连续纤维复合材料制成;封边绕着梁体的边缘环绕一圈设置,由非连续纤维复合材料制成;还包括膨胀体,所述膨胀体由高刚性发泡材料制成,安装于所述复合材料结构体上;以解决现有技术中存在的采用金属制作车身A柱补强板不利于车身的轻量化设计、无法有效避免结构压溃的问题。
