| Abstract: | Composites were prepared with unsaturated polyester resin(UPR) and woodflours which were modified by silicane coupling agent(MW) and unmodified(UW).The effects of modified method and woodflour particle size on the mechanical properties of composites were studied.Comparing with neat UPR,the tensile strength and impact strength of MW/UPR increased by 74.4% and 36.1% while the composite was containing 20(wt)% MW.The relateship between woodflour particle size and mechanical strength was intricacy. |
