The invention relates to the technical field of vehicle structures, and provides a B column reinforcing plate and a manufacturing method thereof and a B column assembly. The B column reinforcing platecomprises an outer-layer reinforcing plate, and an inner-layer reinforcing plate, wherein the outer-layer reinforcing plate is provided with a body extending in the first direction, the body is provided with lightening holes extending in the first direction, and the lightening holes avoid the force bearing area of the B column reinforcing plate; a fiber material is paved on the inner wall of theouter-layer reinforcing plate, the inner-layer reinforcing plate comprises a first basic paving layer corresponding to the area where the body is located, a first reinforcing paving layer corresponding to the area where the lightening holes are located, a second reinforcing paving layer corresponding to the areas where the lightening holes and the force bearing area are located and a second basicpaving layer corresponding to the area where the body is located which are sequentially paved in the thickness direction of the inner-layer reinforcing plate. The lightening holes are formed in the outer-layer reinforcing plate, so that light weight of the B column reinforcing plate is realized; and the inner-layer reinforcing plate, the reinforcing lightening holes and the force bearing area areformed through variable-thickness multi-layer paving of fiber materials, so that the strength and the performance of the B column reinforcing plate are improved.
本发明涉及车辆结构技术领域,提供一种B柱加强板及其制作方法、B柱总成。其中B柱加强板包括:外层加强板,具有沿第一方向延伸的本体,本体设有沿第一方向延伸的减重孔,减重孔避开B柱加强板的承力区;内层加强板,通过纤维材料铺贴于外层加强板的内壁,内层加强板沿其厚度方向包括依次铺贴的:对应本体所在区域的第一基础铺层、对应减重孔所在区域的第一增强铺层、对应减重孔和承力区所在区域的第二增强铺层和对应本体所在区域的第二基础铺层。本发明通过外层加强板设置减重孔,实现B柱加强板轻量化;通过纤维材料变厚度多层铺贴形成内层加强板,补强减重孔和承力区,实现B柱加强板强度和性能提升。
