摘　　要：以不饱和聚酯树脂为基体,玻璃微球为增强体,制备了玻璃微球增强不饱和聚酯树脂微孔塑料.通过研究玻璃微球对微孔塑料微观形貌、压缩强度和冲击韧性等力学性能的影响,得到了具备优良综合性能材料的较优配方.研究结果表明:与不加玻璃微球的不饱和聚酯树脂塑料相比,随着微球含量增加,材料的冲击韧性从2.66KJ/m2提高至8.15KJ/m2;压缩强度从82.77MPa提高至95.33MPa.从SEM照片中可以看出,微球的存在阻止了基体内裂纹的扩展,提高了材料的力学性能.The unsaturated polyester resins （UPR） microcellular plastic was prepared with hollow glass microspheres as reinforce .Study the effects of hollow-spheres on the micro-structure ,compressive strength and impact strength of the composite and obtains a optimum formula that can make composite with good comprehensive mechanical properties .The result shows that compared with no hollow-spheres added material ,when increasing glass micro-spheres ,the compressive strength will be improved from 2 .66 KJ/m2 to 8 .15 KJ/m2 and the impact strength will be improved from 82 .77 MPa to 95 .33 MPa .It can be inferred from SEM pictures that the existence of hollow glass microspheres in composite can prevent the inner cracks from growing and improve the mechanical properties .
