Abstract

Incompatibility between basalt fibers and phenolic resin matrices leads to poor interfacial bonding in their composites. This study aims to investigate the effects of plasma treatment on the basalt fiber surface properties. The scanning electron microscopy shows increased fiber surface roughness due to plasma treatment, which favors mechanical interlocking of the interface; The water contact angle test shows the plasma treatment technique do not wreck the wettability of basalt fibers. The result of the single fiber tensile strength indicates that the plasma treatments has no detectable influence on the basalt fiber tensile strength. Micro-bond test shows the changes of the interfacial shear strength of the basalt fibers. The interfacial shear strength (IFSS) are raised 41% when plasma treatment time are 30 and 40s, while 19% when plasma treatment time are 20s. Therefore, it can be concluded that the plasma treatments on the basalts can improve the basalt fibers' compatibility to the phenolic resin.
