Abstract

The reinforcement carbon fibers were modified using low pressure oxygen plasma treatment to attain the better adhesion between their surfaces and matrix of various composite materials. We investigated the influence of plasma treatment duration on the surface morphology, wettability and mechanical properties of carbon fibers. Three different times of plasma treatment were studied (1, 2 and 4 minutes) together with untreated samples. The fiber surface morphology changes were studied using scanning electron microscopy. The other studied parameters were the fiber modulus of elasticity and tensile strength. The results showed that 4 minutes of plasma treatment had a positive effect on the fibers surface morphology and wettability while no or limited effects on mechanical properties were found.

Keywords: Carbon fibers, plasma, SEM, tensile strength, modulus of elasticity
