Improved interfacial adhesion and manufaturing method of MGF/P-DCPD composites using W, MO, or RU type catalysts in air condition

Abstract

Dicyclopentadiene (DCPD) resins are manufactured commercially using Reaction Injection Molding (RIM) process. DCPD has valuable properties with good impact resistance, low temperature resistance and water-resisting. In particular the impact properties are much better than epoxy resins. The application of DCPD resins includes forklift, fork crane, dump truck and heavy vehicles. The manufacturing time need to be reduced and the mechanical properties of DCPD resin also can be improved by adding reinforcement materials. In this work, compression molding method was used to improve mechanical properties of DCPD. The optimum curing conditions of DCPD were investigated with pressure, temperature, and stirring time and speed in the curing conditions. In addition, the mechanical property of DPCD was improved by adding reinforcement such as carbon fiber and glass fiber. After mechanical measurement at different conditions, the optimum curing condition of DCPD resin was obtained as 80~100 C in temperature, 15 psi in pressure, 200 rpm in stirring speed and 70 seconds in stirring time. After adding reinforcement materials such as chop carbon and glass fiber, the DCPD composites exhibited even worse mechanical properties. Surface treatment of reinforcing fibers and modification of DCPD catalysts should be studied continuously. © 2015 International Committee on Composite Materials. All rights reserved.
