摘　　要：以芝麻秸秆粉为增强材料、不饱和聚酯树脂(UPR)为基体制作秸秆粉/UPR复合材料。探究了秸秆粉用量、粒径对复合材料的密度、拉伸强度、弯曲强度及吸水率的影响。结果表明,粒径为100目、用量为10%的芝麻秸杆粉/UPR复合材料的综合力学性能最好,拉伸强度和弯曲强度分别达到41.32 MPa和67.47 MPa,吸水率最低,仅为0.77%。Sesame straw powder(SSP)/UPR composites were prepared by using SSP as filler and unsaturated polyester resin(UPR) as matrix. The effects of the dosage and particle size on the density, tensile strength, flexural strength, and water absorption of the composite were investigated. The results show that, the SSP/UPR composite containing 10%(wt) SSP of 100 mesh has the best mechanical properties and the least water absorption.
