Abstract

The invention discloses a preparation device and method of long-fiber-reinforced thermoplastic resin composite material.The preparation device comprises a base and two conveying belt mechanisms arranged on the base.Each conveying belt mechanism comprises a conveying belt which is arranged between a drive wheel and a driven wheel in a sleeved manner and tensioned by the two, and a conveying face is formed on the surface of the conveying belt.The two conveying belt mechanisms are identical in structure, the conveying face of one conveying belt mechanism is stacked above the conveying face of the other conveying belt mechanism, and the gap and the included angle between the upper conveying face and the lower conveying face are adjustable.The preparation device has the advantages that the device is simple and practicable in structure and process and high in production efficiency; the thermal history of resin melt strips and fibers during the forming process is short, and damage to the length and mechanical strength of the fibers is small; the included angle between the two conveying belts allows the conveying belts to twist the resin melt strips and the fibers during traction, and the combination performance of the fibers and the resin melt strips is increased.

Description

technical field [0001] The invention relates to the preparation of composite materials, in particular to a preparation device and method of long fiber reinforced thermoplastic resin composite materials. Background technique [0002] Composite materials are another widely used material after wood, metal, and plastic, and are widely used in energy, chemical, medical, military and other fields. Composite materials are materials with new properties composed of two or more materials with different properties through chemical or physical means on the macroscopic (microscopic) level. The performance of various materials learn from each other, so that the comprehensive performance of the composite material is better than that of a single resin melt strip material. The resin melt strip materials of composite materials are divided into two categories: metal and non-metal. Aluminum, magnesium, copper, titanium and their alloys are commonly used in metal resin melt strips. Non-metall...
