Effect of Compatibilizer on the Properties of Fluorinated and Oxy-fluorinated Short Kevlar fiber Reinforced EP

This paper concentrates on the effect of compatibilizers on the thermal, dynamic mechanical, crystalline and rheological properties of unmodified fluorinated and oxy-fluorinated short Kevlar fiber reinforced ethylene propylene copolymer (EP). The compatibilizers used in this study are maleic anhydride grafted Polypropylene (MA-gPP). The composites were prepared in a brabender mixer and were molded in a compression molding. The compatibilized samples show improved thermal, dynamic mechanical crystalline as well as rheological properties as a result of better adhesion between the fiber and matrix at the interface. The compatibilizing effect is much more pronounced in the case of oxy-fluorinated Kevlar/EP composites in comparison with the untreated and fluorinated Kevlar/EP composites.
