Device and method for production of long-fiber-reinforced thermoplastic resin

Abstract

The invention discloses a device and a method for the production of long-fiber-reinforced thermoplastic resin, wherein the production device comprises a melt impregnation chamber, in which a resin melt for impregnating fiber bundles is accommodated and one sidewall of which is provided with fiber bundle inlets as well as the other sidewall of which, in opposition to the sidewall provided with the fiber bundle inlets, is provided with fiber bundle outlets, wherein the number of the fiber bundle outlets is smaller than the number of the fiber bundle inlets. During the production, a fiber bundle requiring impregnation is divided into at least two bundles, each fiber bundle enters the melt impregnation chamber through one of the at least two fiber bundle inlets, is then impregnated in the resin melt and passes by the surface of a plurality of tension rollers to stretch out of one fiber bundle outlet to synthesize a fiber-reinforced resin bundle.

AI Technical Summary

Benefits of technology

This technology helps create stronger materials for use in various industries such as construction or automobiles. By dividing the necessary amount of fibrous material into smaller sections called segments, it becomes easy to break down when needed without losing its strength over longer periods. Additionally, this technique allows for quicker passage of these fragments during manufacturing while maintaining their integrity. Overall, this new method enhances the properties of composite materials made from them.

Problems solved by technology

Technologies described in this patents involve developing new types of materials called long fibergrexed (LF) or extended fibrous reinfusion (EFR). These compositions can improve physical strength, flexibility, heat tolerance, impact resistance, creepage resistance, and durability while reducing costs compared to traditional methods like casting. They use special techniques to increase their ability to absorb liquid ingredients without causing them to clump around each other inside the manufacturing apparatus. Additionally, they aim to reduce defective parts caused by excessively injected polymeric resin when producing these items. Overall, LFT/EPFLAR™ provides better control over both mass ratio and thickness of filaments within the final part of injection molds, resulting in lower production efficiencies and reduced costs associated with making advanced components made from sinterable powder metal compounds.
