Abstract
The objective of this study is to improve the mechanical properties in abaca fabric/epoxy composites produced using a VARTM process. The mechanical properties were improved by increasing the surface roughness of the fabric through plasma polymerization and improving the interfacial adhesion between the epoxy and the fabric through changing its hydrophilic properties to the hydrophobic properties. Plasma polymerization at atmospheric pressure and room temperature was used, and the optimal polymerization time to improve the mechanical properties was investigated. NaOH treatment on the fabric was also carried out for the comparison. The composite fabricated using the fabric polymerized for 10 seconds shows the highest tensile strength compared to that of none-polymerized or NaOH treated. Plasma polymerization for more than 20 seconds exhibits decrease in the tensile strength. As a result, the plasma polymerization for more than 20 seconds may have caused some damages on the surface of the fabrics. Also, the hydrophilic abaca represents a tendency of presenting the hydrophobic properties in absorption and sedimentation tests.
