Randomly reversed isolation structure silicone rubber-based wave-absorbing composite material and preparation method thereof

By randomly distributing short-cut carbon fiber/silicone rubber composite filler in a silicone rubber matrix, and abandoning the high-precision preparation process, a low-cost, large-scale production of randomly reversed isolation structure silicone rubber-based microwave absorbing composite material was achieved. This solved the problems of complex preparation and high precision requirements in the existing technology, and provided wideband and high-efficiency microwave absorption performance.

Abstract

本发明涉及聚合物基复合材料加工成型技术领域，具体为一种随机反转隔离结构硅橡胶基吸波复合材料及其制备方法，包括硅橡胶基体，以及分散在硅橡胶基体中的多个亚波长尺度的短切碳纤维 / 硅橡胶均匀结构复合填料；其中，短切碳纤维 / 硅橡胶均匀结构复合填料随机分布在硅橡胶基体中，且相邻的短切碳纤维 / 硅橡胶均匀结构复合填料之间互不接触，从而在硅橡胶基体内形成随机反转隔离结构；所述短切碳纤维 / 硅橡胶均匀结构复合填料中，短切碳纤维的含量为70 wt.%；解决了现有吸波材料存在的制备工艺复杂、对结构精度要求高、难以实现低成本规模化制备的问题。
