In the present work, all polypropylene composites were prepared by film stacking technique using terpolymer and copolymer

matrixes and woven fabric reinforcement. Composite sheets were prepared by use of hot press at different processing temperatures of 5,

10 and 15 °C over the melting temperature (Tm) of the matrixes in constant pressure of 8 MPa. Consolidation quality of composites was

studied by scanning electron microscopy (SEM) and density measurements. Mechanical properties of composite sheets were subjected

to tensile, flexural, and impact tests. The results showed that strength, stiffness and consolidation quality of composites increased by

increasing the processing temperature while impact properties decreased. It was established that composite with terpolymer matrix

demonstrated good strength, stiffness as well as consolidation properties in lower preparing temperature that indicate terpolymer matrix

can expand the processing window in manufacturing of all polypropylene composites.
