Beschreibung
Zusammenfassung:The invention relates to the technical field of metal composite materials, belongs to the IPC classification number B29C70/84, and particularly relates to a light impact-resistant composite material for aviation and a preparation method thereof. The composite material is a sandwich plate and is formed by bonding a skin, a core material and the skin from top to bottom through an adhesive. Compared with the prior art, the dot matrix sandwich structure prepared from the brand new Ti6Al4V (Ti64) titanium alloy powder is provided, and compared with a foam structure, the dot matrix sandwich structure has higher strength, rigidity-weight ratio and impact resistance. 本发明涉及金属复合材料技术领域，所属IPC分类号B29C70/84，具体涉及一种用于航空的轻质抗冲击复合材料及其制备方法。所述复合材料为夹心板材，由蒙皮、芯材、蒙皮从上至下通过胶粘剂粘结。与现有技术相比，本发明提出来了一种全新的Ti6Al4V(Ti64)钛合金粉末制备的点阵夹芯结构，这些结构与泡沫结构相比具有更高的强度、刚度重量比和抗冲击性能。
