Abstract

The present disclosure provides a molding system for preparing a fiber-reinforced thermoplastic composite article. The molding system includes: a molding machine; a mold disposed on the molding machine and having a mold cavity for being filled with a composite molding material including a polymeric resin and a plurality of fibers; a processing module configured to generate an anisotropic stress distribution of the composite molding material in the mold cavity based on a molding condition for the molding machine; and a controller coupled to the processing module and configured to control the molding machine with the molding condition to perform an actual molding process for preparing the fiber-reinforced thermoplastic composite article. The anisotropic stress distribution of the composite molding resin is generated based in part on consideration of an integral effect of an elongational viscosity and a shear viscosity of the composite molding material.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This patent application claims priority under 35 U.S.C. § 119(e) from Provisional Patent Application No. 62 / 625,061, filed on Feb. 1, 2018, the disclosure of which is incorporated by reference herein in its entirety, including all exhibits appended to Provisional Patent Application No. 62 / 625,061.TECHNICAL FIELD[0002]The present disclosure relates to a molding system for preparing a fiber-reinforced thermoplastic (FRT) composite article, and more particularly, to an injection molding system for preparing an FRT composite article using a computer-aided engineering (CAE) simulation.DISCUSSION OF THE BACKGROUND[0003]Fiber-reinforced thermoplastic (FRT) composite articles, produced by molding techniques such as injection molding, have assumed great importance in the manufacture of many products due to their specific mechanical properties, including tensile strength, electrical conductivity, and other characteristics. In order to optimize the q...
