Abstract

A study was performed to investigate the processing parameters of thermoplastic composites. Three configurations of compression molding dies were machined and used to produce composite specimens. Composite specimens made of AS4/Nylon-6 and AS4/Polyphenylene Sulfide (AS4/PPS) prepreg tape were manufactured under four processing conditions. The processing parameters that were studied were maximum pressure and the dwell time at maximum pressure and temperature; A total of twenty-four specimens were made. Cross sections of each were analyzed for fiber volume fraction using a microscope and image analysis software. Each specimen was then loaded in three-point benDing Maximum flexural stress and modulus were determined for each specimen. Increases in fiber volume fraction, maximum stress, and modulus were found as functions of pressure and dwell time.
