| Abstract: | In order to develop new composite material, the glass fiber reinforced composite based on unsaturated polyester/polyurethane IPNs was prepared and its dynamical mechanical property and its application properties were investigated. Arrhernius equation was used to characterize the change of the module with temperature and PU contents. The active energies of various composites were calculated by the relaxation curves. PU decreases relaxation active energy of the composite material. The results indicate that through forming IPNs in the composite matrix, the polyurethane moiety(5%~10%) benefits the impact strength of this composite without remarkable deteriorating its tensile and flexural strength. This work shows a new method to improve the properties of composite materials. |
