摘要

Optimum interfacial conditions are important in the fabrication of glass fiber (GF)/p-DCPD composites to enhance mechanical and impact properties. In this study, different GFs were used in the manufacture of p-DCPD composites and their interfacial and wetting properties compared. Interfacial properties of different GFs and p-DCPD were compared using interfacial shear stress (IFSS). IFSS was determined using a fragmentation test of dual fiber composite (DFC) and cyclic loading tensile tests. The CR-212 GF/p-DCPD composite was the best IFSS to 60.2 MPa than others and cyclic loading tensile strength decreased the slightest than others. Wetting properties were obtained from dynamic contact angle measurement and the variation of static contact angle. The p-DCPD wetted the quickest to CR-212 GF in 2 s than others. Surface energy and work of adhesion of different GFs and p-DCPD were calculated using the dynamic contact angle. The CR-212 GF/p-DCPD was the best work of adhesion than others. Sizing agent of different GFs was extracted using an acetone extraction method and compared using FT-IR spectra. The CR-212 GF exhibited the most hydroxyl group than others. Mechanical properties of different GFs and p-DCPD composites were compared using tensile, flexural and Izod impact test at room and low temperature. The CR-212 GF/p-DCPD composites exhibited the most tensile, flexural and Izod impact test at room and low temperature than other composites. The relationship between interfacial properties and mechanical properties was determined and optimum fiber sizing conditions were obtained using these all results. The GF/p-DCPD composites will be applied to external material of heavy vehicle and military field because of high impact properties at room and low temperature.
