Lightweight aluminum alloy composite material for automobile and preparation method of lightweight aluminum alloy composite material
The invention provides a light-weight aluminum alloy composite material for automobiles, the light-weight aluminum alloy composite material is of a sandwich structure, the sandwich structure is composed of a core layer, a surface layer and a protective layer, the hardness of the core layer, the hardness of the surface layer and the hardness of the protective layer are different, and the strength of the surface layer and the strength of the protective layer are both larger than the strength of the core layer. The preparation method comprises the following steps: dissolving AlCl36H2O in water to obtain an AlCl3 solution, then adding Al powder, carrying out a heating reflux reaction to obtain transparent sol, aging the sol, adding a PVP ethanol solution, and uniformly stirring to obtain a spinnable sol precursor; s2, performing electrostatic spinning by adopting an electrostatic spinning instrument to obtain a precursor film; s3, setting the precursor film as a surface layer, a core layer and a protective layer, and respectively dipping the surface layer and the protective layer of the precursor film in a polycarbosilane solution to obtain a composite precursor film; s4, calcining the composite precursor membrane to obtain a composite ceramic membrane; and S5, molten aluminum is poured on the composite ceramic membrane, and the light-weight aluminum alloy material is obtained.
本发明提供了一种汽车用轻量化铝合金复合材料，所述轻量化铝型材为三明治结构，所述三明治结构由芯层、面层和保护层三部分组成，所述芯层，面层和保护层的硬度不同，所述面层和保护层的强度均大于芯层的强度，其制备方法为：将AlCl3•6H2O溶解于水中，得到AlCl3溶液，然后加入Al粉，加热回流反应，得到透明的溶胶，将溶胶老化后，加入PVP乙醇溶液，搅拌均匀后，得到可纺性溶胶前驱体；S2.采用静电纺丝仪器进行静电纺丝，得到前驱体膜；S3.将前驱体膜设为由面层，芯层和保护层，分别将前驱体膜面层和保护层的部分浸渍于聚碳硅烷溶液中，得到复合前驱体膜；S4.将复合前驱体膜进行煅烧，得到复合陶瓷膜；S5.将铝液浇注在复合陶瓷膜上，得到轻量化铝合金材料。
