Problems solved by technology

However, the support structure in the spacecraft antenna subsystem not only has predetermined requirements for the bearing capacity of static loads, but also has specific requirements for the product's structural weight, wave-transmitting performance, electrical performance, and its ability to withstand dynamic loads and local impact loads. More stringent requirements, so the traditional brittle carbon fiber reinforced resin matrix composite skin (hereinafter referred to as carbon skin) and aluminum honeycomb sandwich core cannot be used

Abstract

The invention relates to an aramid skin-paper honeycomb sandwich shell structure and its preparation method and application, in particular to a Kevlar49 aramid fiber woven cloth reinforced epoxy resin base compound applied to the support structure of the spacecraft antenna subsystem The material skin-Nomex porous aramid paper honeycomb sandwich shell structure and its preparation method belong to the field of aerospace composite material structure and its forming technology.

Description

technical field [0001] The invention relates to an aramid skin-paper honeycomb sandwich shell structure and its preparation method and application, in particular to a Kevlar49 aramid fiber woven cloth reinforced epoxy resin base compound applied to the support structure of the spacecraft antenna subsystem The material skin-Nomex porous aramid paper honeycomb sandwich shell structure and its preparation method belong to the field of spacecraft composite material structure and its forming technology. Background technique [0002] The honeycomb sandwich shell structure has outstanding advantages such as light weight, high specific strength, high specific stiffness, and high bending stiffness, and under the same load conditions, it has smaller deformation and stress than solid structures, so it has been widely used in spacecraft The main load-bearing structure and secondary load-bearing structure, such as the satellite central load-bearing cylinder in the spacecraft structure su...
