| Abstract: | Short-fiber reinforced polypropylene (PP) composites are very attractive due to their easy fabrication,economy and superior mechanical properties. Injection molding process is the main method to molding short fiber reinforced polymer (SFRP) composites. Shrinkage is one of several important indexes determining the quality of injection molded parts,and non-uniform shrinkage is a main cause of the part warpage. In this paper,computer-aided engineering(CAE) and Taguchi design of experiments(DOE) technique were ... |
