Performance of rotary jet melt spun polypropylene fiber reinforced polyester composites

Nowadays, in many engineering applications, it is not possible to use one type of material that can satisfy all thedesired properties. The composite industry solves the mentioned problem by using several components at the same time.Finding materials that can improve the properties of composites is very important. This study investigated the effect ofadding polypropylene (PP) sheets to the polyester resin. At first, PP fibers were made from PP granules by rotary jetmelt spinning machine and produced fibers compacted into polymer sheets by roller mixer. Next, to produce PPcomposite, polyester resin, cobalt and hardener were added to PP polymer by manual mixing. Finally, the composite'smechanical properties such as bending strength and impact resistance were measured. The results of the present studyshowed that in the presence of resin, the mechanical properties of the composite are significantly improved compared tonon-composite plates.
