Preliminary Study on Injection Molding Process of Single Polymer Composites
(0) An approach of preparing single polymer composites (SPCs) by injection molding was demonstrated.Polypropylene (PP) was used as a model system to investigate this method.The thermal properties of PP granules and PP fibers were analyzed by Differential Scanning Calorimeter (DSC) to determine the processing temperatures.The flexural test of PP SPCs showed that the flexural strength was obviously improved compared to the non-reinforced PP.The results also indicated that the injection pressure,holding pressure and nozzle temperature greatly affect the flexural strength of PP SPCs.The microstrueture observation showed no gaps between fibers and the matrix by using Scanning Electron Microscopy (SEM).The matrix melt was able to penetrate into fiber webs and the two materials had good interfacial compatibility.
