  Abstract

In order to develop the high impact resistant composites with high mechanical properties, carbon fiber composites of polycarbonate matrix having high toughness were studied. Carbon fiber reinforced polycarbonate (carbon/polycarbonate) composites were manufactured by a hot press molding under different temperature (270−285oC) and pressure (1.5−5 ton/in2) conditions. The mechanical properties of flexural, interlaminar shear strength, impact energy and morphological features of the carbon/polycarbonate composites were investigated with the molding conditions. The carbon/polycarbonate composites manufactured at 280oC and 3.5 ton/in2 for 3 min. was found to have maximum flexural strength of 820 MPa and interlaminar shear strength of 55 MPa due to the effects of high matrix impregnation and good fiber alignment. On the other hand, the maximum impact resistance of the composite appeared at low flexural strength and interlaminar shear strength.
