Misaligned splicing casting preparing method used for flexible skin/electronic skin of high-speed aircraft

Abstract

The invention provides a misaligned splicing casting preparing method used for a flexible skin / electronic skin of a high-speed aircraft. The method specifically comprises the steps that a mold structure model is built, and according to the mold structure model, a mold is made, the melting point T2 of the mold is smaller than the highest bearing temperature T1 of the flexible skin / electronic skin;a liquid-state flexible material and a curing agent for making the flexible skin / electronic skin are evenly mixed, a mixture is poured into the mold, the mixture of the flexible material and the curing agent is leaked out of a tail-stage pipeline of an inner three-dimensional structure, and curing is carried out at the temperature T3; a combination part is heated at the temperature T4, T4 is larger than T2 and smaller than T1, the mold is melted, and is separated from the solid-state flexible material, and the flexible skin / electronic skin is obtained. The characteristic that the mold materialmelting point is lower than the flexible material highest bearing temperature is used, misaligned splicing separation is achieved, the mold and the flexible skin / electronic skin can be effectively separated, integral forming of the flexible skin / electronic skin of the inner complex three-dimensional structure is achieved, and extension and bending of the flexible material are protected.

Description

technical field [0001] The invention belongs to the technical field of flexible electronics, and in particular relates to a method for preparing a high-speed aircraft flexible skin / electronic skin by fusion casting, which is used for the preparation of micro-nano structures of the flexible skin / electronic skin.
