Abstract

The present invention discloses pulse type shock reinforced in-line mixing and injecting forming method and apparatus. Pulse type shock is introduced into the whole in-line mixing and injecting forming process of producing fiber reinforced composite polymer material. The apparatus includes one plasticizing extruder with three screws arranged in one line and including one main screw capable of generating periodical axial pulse shock, one buffering storing device, and one pulse type shock pressure reinforcing plunger injecting device. The present invention can lower melt viscosity, raise mixing and homogenizing effect, raise the compatibility between fiber and polymer, lower the processing power consumption and raise product quality.

Description

Technical field [0001] The invention belongs to the field of fiber-reinforced polymer-based composite material molding and processing methods and equipment, and specifically refers to a pulse-type impact-reinforced online compounding injection molding method and equipment. Background technique [0002] Due to the good mechanical properties and recyclability of fiber-reinforced polymer composites, they are widely used in industries such as automobiles, machinery, electrical appliances, construction, boats, and aerospace. The methods of processing and forming fiber-reinforced polymer-based composite materials mainly include "two-step" molding, online compounding injection molding, and extrusion molding. The fiber-filled polymer matrix composite material has poor melt fluidity, difficult processing, and easy fiber breakage during processing, which affects the fiber length and length distribution in the product, and seriously affects the quality of the product. Therefore, new molding...
