The invention discloses a composite material access port cover plate for an automobile. Two connecting lugs are arranged on one long edge and two short edges of the cover plate respectively, and two clamping blocks are arranged on the other long edge of the cover plate; the cover plate body is made of chopped glass fiber thermoplastic composite materials, continuous and criss-cross reinforcing ribs are arranged on the back face of the cover plate, the reinforcing ribs in the middle of the cover plate are densely distributed, and the reinforcing ribs on the periphery of the cover plate are loosely distributed. The cover plate is reasonable in structure and simple in preparation process, the chopped glass fiber thermoplastic composite material is adopted as a preparation main material, the cover plate has the advantages of being light in weight, low in cost and high in plasticity, the continuous and criss-cross reinforcing rib arrangement pattern on the back face of the cover plate is matched, the lightweight effect of the cover plate structure is remarkable, and high engineering application value is achieved.
本发明公开一种汽车用复合材料检修口盖板,在盖板的一条长边和两条短边上分别设有两个连接耳、在另一条长边上设有两个卡块;盖板主体以短切玻纤热塑性复合材料制成,在盖板背面设有连续且纵横交错的加强筋,且盖板中间部分的加强筋分布密集、外周部分的加强筋分布宽松。该盖板的结构合理,制备工艺简单,采用短切玻纤热塑性复合材料作为制备主材具有质量轻、成本低、可塑性较强的优势,配合盖板背面的连续且纵横交错的加强筋布置格局,使得该盖板结构的轻量化效果显著,具有较高的工程应用价值。
