混杂热塑性复合材料/金属层压材料是极具潜力的轻量化汽车车身板材料。它们具有优良的表面质量和标准复合材料板的联接。我们研究了这些混杂层压材料的抗撞凹性能,并与传统的金属汽车车身板材料进行了比较。以固定的抗挠刚度,按不同的金属和复合材料比率,使用钢和铝与编织和无规则玻璃纤维增强聚丙烯生产了一系列测试板材。准静态的增量抗撞凹性能测试是通过一个直径25.4mm的半球形压头进行的。与金属材料相比,混杂层压材料的抗撞凹性能更好。抗撞凹性能随着复合材料/金属比率的升高而提高。
Hybrid thermoplastic composites / metal laminates are highly potential lightweight automotive body panel materials. They have excellent surface quality and standard composite board connection. We studied the anti-bump properties of these hybrid laminates and compared them with the traditional metal automotive body panel materials. A series of test panels were produced with fixed flexural rigidity at various metal and composite ratios, using steel and aluminum and braided and random glass fiber reinforced polypropylene. The quasi-static incremental crashworthiness test is performed with a 25.4 mm diameter hemispherical indenter. The impact resistance of hybrid laminates is better than metallic materials. Crash resistance performance increases with the composite / metal ratio.
