By introducing functional fillers into the ethylene propylene diene monomer matrix, the anti-ablation, thermal insulation, and adhesive layer were prepared, respectively. We have studied the mechanical properties, ablation properties, thermal insulation properties, and bonding properties of different composite structures after design and analyzed the ceramic mechanism. The results showed that the content of ceramic fillers improved the thermal stability and ablation properties of anti-ablation layer composites. The formation of liquid structure can fill the hole defects and ablation pit. The foaming agent improved thermal insulation properties of the thermal insulation layer, and the strength of the bonding layer has been greatly improved. The design of the composite structure can not only reduce the density but also have an excellent thermal insulation effect. And as the thickness of the heat insulation layer increases, the heat blocking effect becomes more excellent.

复合材料结构设计对乙丙二烯单体复合材料烧蚀性能的影响

通过将功能性填料引入乙丙二烯单体基体，分别制备了抗烧蚀层，隔热层和粘合层。设计后，我们研究了不同复合结构的机械性能，烧蚀性能，隔热性能和粘结性能，并分析了陶瓷机理。结果表明，陶瓷填料的含量提高了抗烧蚀层复合材料的热稳定性和烧蚀性能。液体结构的形成可以填补孔的缺陷和烧蚀坑。发泡剂改善了绝热层的绝热性能，并且粘结层的强度已大大提高。复合结构的设计不仅可以降低密度，而且具有出色的隔热效果。并且，随着隔热层的厚度增加，隔热效果变得更加优异。
