Abstract

This invention relates to fiber-reinforced shape memory composite and its application. This invention solves the problems of low hardness and strength, poor reconversion performance, and poor motion stability band reliability faced by present shape memory polymer materials. The fiber-reinforced shape memory composite is composed of: shape memory polymer material 20-95 vol. %, and reinforcing fiber material 5-80 vol. %. The fiber-reinforced shape memory composite has such advantages as high reconversion strain, strong force output during reconversion, high motion stability and reliability, low density, high hardness, and high strength. The method has such advantages as simple process and easy operation. The fiber-reinforced shape memory composite can be used in such industries as toys, medicine, architecture, traffic, aviation, aerospace, etc.

Description

technical field [0001] The invention relates to a shape memory composite material and its application. Background technique [0002] Intelligent materials and structures are an emerging multidisciplinary comprehensive science, covering materials, mechanics, mechanics, electronics, control, electromagnetics and other disciplines, and are at the forefront of the development of current engineering disciplines. In the past few decades, smart materials have been widely used in military and civilian fields such as aviation, aerospace, ships, and construction. Smart materials are developing at an unprecedented speed in bionics, sensors, actuators, etc. Among them, shape memory polymers are being used more and more widely because of their excellent comprehensive properties. [0003] Shape memory polymer materials generally have a two-phase structure: one phase is a stationary phase of the shape of the shape memory material, and the other phase is a reversible phase. The stationary...
