Problems solved by technology

Polycarbonate is a kind of tough thermoplastic resin, and it is the fastest-growing general-purpose engineering plastic among the five major engineering plastics. It has flame retardancy, wear resistance, and oxidation resistance. Carbonate has low mechanical properties, is not resistant to ultraviolet light, and is not resistant to strong alkalis, which limits its application in engineering plastics

Description

Technical field [0001] The invention relates to the technical field of composite materials, in particular to a polycarbonate environmentally friendly flame-retardant composite material. Background technique [0002] Composite materials are composed of two or more materials with different properties, through physical or chemical methods, to form materials with new properties on the macro (micro). Various materials complement each other in performance and produce a synergistic effect, so that the comprehensive performance of the composite material is better than the original constituent materials to meet various requirements. The matrix materials of composite materials are divided into two categories: metal and non-metal. Commonly used metal substrates are aluminum, magnesium, copper, titanium and their alloys. Non-metallic substrates mainly include synthetic resin, rubber, ceramics, graphite, carbon and so on. Reinforcing materials mainly include glass fiber, carbon fiber, boro...
