Abstract

The invention relates to a composite material with high obstruction and high performance and a preparation method thereof. The composite material with high obstruction and high performance is a laminated body sequentially compounded by a polyfluoroethylene thin film layer, a polyurethane adhesive layer, an AL / PET film layer, a polyurethane adhesive layer, a Kevlar fabric layer and a polyurethane coating. The composite material can ensure lower gas permeability and good mechanical properties and fatigue resistivity under the condition of lighter quality and can be really adapted to the application requirement on the material with high obstruction in the aerospace field. The preparation method is a dry method solvent-free composite technology, the solid content of adhesive used for the method is 100 percent, and no solvent is contained. The method has the great characteristics of environment protection, high product hygiene index and product quality guarantee.

Description

technical field

[0001] The invention relates to a high-barrier high-performance composite material and a preparation method thereof, in particular to a class of novel composite materials suitable for aviation and aerospace fields. Background technique

[0002] At present, the high-barrier materials we are familiar with in China are mostly used in packaging and medical and health fields, but the high-barrier materials suitable for aviation and aerospace fields cannot really meet the requirements. High-performance film materials for aviation generally require properties such as heat resistance, flame retardancy, low temperature resistance, high strength and low weight, insulation, waterproof and moisture resistance, etc. It is difficult for film materials on the market to take into account these properties. Some film materials are often too heavy or thick to meet the requirements of light weight under the condition of ensuring low gas permeability; some film materials can meet...
