Electrochemical Pretreatment

This work demonstrates the efficacy in performing an electrochemical pretreatment on carbon fibres to improve the effect of plasma polymerization of acrylic acid on these surfaces. Modified samples demonstrated improve physical properties including tensile strength and Young’s modulus, as well as an increase in composite performance as measured by the interfacial shear strength. The electrochemical pretreatment was shown to enhance the advantages observed when coating fibres using plasma polymerization.

Water Absorption Test

In this study, effects of water absorption and adding resin particles around fiber on interfacial shear strength of carbon fiber (CF)/maleic anhydride grafted polypropylene (MAPP) were investigated. In water absorption test, CF/MAPP specimen was immersed in distilled water at room temperature for four weeks. Micro debonding test of water absorbed CF/MAPP was conducted. Micro debonding test of Resin particle added Carbon Fiber (RCF)/MAPP was also conducted. The resin particle size was less than 5μm. Fracture surface of RCF/MAPP was observed by using Scanning Electron Microscope (SEM). As a result, following conclusions are obtained. In case of water absorbed CF/MAPP, the interfacial shear strength decreased 34% compared with that of virgin. The reason is thought that the interface between fiber/matrix was weakened by absorbing water. In case of resin particle, interfacial shear strength of RCF/MAPP increased 34% compared with that of CF/MAPP. From fracture morphology of RCF/MAPP, resin particles on CF surface were found. Therefore, interfacial shear strength of CF/MAPP was increased by the friction on the surface of carbon fibers.
