Abstract
The fiber-particulate composites in general present superior behavior in terms of mechanical properties than the materials loaded only with mineral filler, except for the formulation that has 60% mica which reached values comparable to those of the composites reinforced also with FV. Compounds with mica/FV and talc/FV show better synergism in relation to CaCO3. The incorporation of mineral fillers and/or FV in polypropylene increases the flexural and elastic modulus by up to 3.53 and 4.3 times, respectively. Among the composites studied, mica in high concentration proved to be a very promising alternative since it has good mechanical properties and a very low cost when compared to fiber- particled and/or compatibilized systems. FV contributes to higher strength and modulus values. The result with only recycled polymer suggests that with the use of recycled material from industrial scraps and greater refinement in the study, quite satisfactory properties can be achieved with the use of 100% recycled resin.
