The effect of micro-bubbles elimination prior resin infusion process

Abstract

The treatment of resin mixture prior to resin infusion is discussed. The elimination of micro-bubble due to entrained air during mixing process had been done using a novel technique of capillary separation method. In this process micro-bubbles were separated from viscous resin mixture, thus bubble-free resin was produced and then infused. Tested samples using treated resin experimentally showed less void contents and higher tensile strength.
