Description
Technical field
Preparation more particularly to a kind of system of fiber reinforced thermoplastic resin composite material the present invention relates to composite material
Standby apparatus and method.
Background technology
Composite material be after timber, metal, another material largely used after plastics, be widely used in the energy, chemical industry,
The fields such as medical treatment, military project.Composite material be by two or more material of different nature by way of chemically or physically,
Material of the composition with new performance on macroscopical (microcosmic).Learn from other's strong points to offset one's weaknesses in the performance of a variety of materials, make the comprehensive of composite material
Close the performance that performance is better than single resin melt billot material.The resin melt billot material of composite material is divided into metal and Fei Jin
Belong to two major class.Metal-resin melt billot is common aluminium, magnesium, copper, titanium and its alloy.Non-metallic resin melt billot mainly has
Synthetic resin, rubber, ceramics, graphite, carbon etc..Reinforcing material mainly has glass fibre, carbon fiber, boron fibre, aramid fiber, carbon
SiClx fiber, asbestos fibre, whisker, wire and hard particulates etc..
In fiber-resin composite, made of thermoplastic resin as resin melt billot and reinforcing fiber
Composite material, comparison thermoset resin fibres reinforcing material have high productivity, simple for process, production and use environmental pollution
Less advantage attracts the concern and research of numerous mechanisms and enterprise in recent years.Wherein use biodegradable polymers and plant
Composite material made of fibres has renewable and environmental sound, has become one of the hot spot of composite material research.
Existing fiber-reinforced thermoplastic resin composite material and preparation method thereof, generally first using the previously prepared tree of method physically or chemically
