Abstract

The invention relates to a fold-resistant composite material. Cobalt phthalocyanine, stearic acid and polyether diol are evenly mixed to be reacted at the temperature of 85 DEG C for two hours to obtain a mixture; 1,3-bis(isocyanatomethyl)-cyclohexan, thioacetamide, bisphenol A dianhydride and polyoxyethylene rosin ester are sequentially added into the mixture to be stirred at the temperature of 110 DEG C for four hours, then phenylcyclohexane and hydroxylamine potassium are added to be stirred at the temperature of 120 DEG C for one hour; at last, polyimide resin, phenoxy resin and tetrazole are added to be stirred at the temperature of 120 DEG C for half an hour, and accordingly a fold-resistant prefabricated object is obtained; then the fold-resistant prefabricated object is placed in a mold, and the fold-resistant composite material is obtained through hot pressing. The fold-resistant composite material has excellent mechanical property and heat resistance, and the application and development requirements of the fold-resistant composite material can be met.

Description

technical field [0001] The invention belongs to the technical field of novel composite materials, and in particular relates to a folding-resistant composite material. Background technique [0002] Materials are the pillars of modern science and technology and social development, and the competition of modern high technology depends to a large extent on the development of material science. The so-called macromolecule usually refers to a macromolecular compound composed of tens of millions of small molecular compounds connected by chemical bonds. General-purpose polymer materials are divided into five categories: plastics, rubber, fibers, adhesives, and coatings. Composite materials are multiphase materials prepared by compounding two or more materials such as metal materials, ceramic materials or polymer materials. Various materials learn from each other in terms of performance and produce synergistic effects. The performance is superior to the original constituent materia...
