▎ 摘　　要

NOVELTY - A composite material integrated with transient state, bearing and hiding is solid-liquid phase change composite material based on thermal trigger. The composite material comprises a phase change substrate and an enhanced phase, which are compounded together through interface action. The phase change substrate undergoes phase change under the heat triggering condition. The enhanced phase comprises a mechanically enhanced phase, a thermally conductive enhanced phase, a photo-thermal enhanced phase and a wave-absorbing enhanced phase. The surface of the composite material is coated with paint. USE - Composite material integrated with transient state, bearing and hiding is used for unmanned aerial vehicle (claimed). ADVANTAGE - The composite material has simple structure, low density, excellent mechanical properties, and radar stealth and visible light stealth functions, and is easy to form, and can be quickly resolved. The composite material can be prepared by simple, and can be made into any desired shape by pouring and molding method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the composite material, which involves selecting phase change substrate, heating and melting the substrate to obtain melt, subjecting to phase change under the heat triggering condition, adding reinforced phase to the melt, mixing uniformly to obtain mixture, adding to a mold, molding, cooling to room temperature, obtaining molded material, selecting paint, and spraying or brushing the paint on surface of the molded material.
