Abstract
Carbon Fiber Reinforced Plastics (CFRP) are expected to be used for car
component parts because of their superior mechanical properties and lightweight
properties. Automotive lightening is expected by using CFRP for these parts. In
addition, considering process time and recyclability, it is desirable to use
thermoplastics resin for the matrix. Polypropylene (PP) is a typical thermoplastic
and superior material for its low specific gravity, good moldability and low
environmental burden, therefore the rate of PP being used has increased
remarkably and it is expected to be used for the matrix of CFRP. However, since
PP has poor interfacial adhesion to CF, improvement of interfacial properties is
necessary. In this study, maleic anhydride-modified polypropylene was used to
improve the interfacial adhesion between carbon fiber and matrix resin.
Continuous carbon fiber reinforced polypropylene was fabricated by the
high-speed compression molding method, and the effect of maleic
anhydride-modified polypropylene on the mechanical properties of CFRP was
examined. In consequence, the mechanical properties of CF/PP were improved by
supplying 12.5wt% of maleic anhydride modified PP to PP.
Keywords: carbon fiber, polypropylene, maleic anhydride.
Keywords
