Mechanical Property Improvement of Plasma Treated Carbon Fiber-Reinforced Polyurethanes (PUR) Composites with SiO2 Filler

The aim of this work is the evaluation of the effects of plasma treatment and the addition of SiO2 on the mechanical properties of carbon fiber/polyurethanes (PUR) composite. A powder impregnation process with integrated inline continuous plasma of carbon fibers was used to produce CF/PUR composite. CF/PUR composite were processed into test laminates by compression moulding and interface dominated composite properties were studied. The tensile, flexural and impact strength of composites containing SiO2 and plasma-treated carbon fibers improved obviously.
