摘　　要：采用微米、纳米和微纳共掺氧化铝作为填料制备了环氧树脂浇注体系,并测试其黏度和力学性能。结果表明:氧化铝粒径越小,对浇注体系的黏度影响越大,可添加量越少;当不同粒径的微米氧化铝添加量为300份时,各浇注体系的力学性能均达到最佳,但冲击强度比树脂基体明显下降;当纳米氧化铝的添加量为2.5份时,浇注体系的冲击强度相比树脂基体提升了10%;微纳共掺能够在单一组分(微米或纳米)基础上使浇注体系的力学性能进一步提高。Micro-Al2O3, nano-Al2O3, and micro-nano co-doped Al2O3 were used to prepare epoxy resin cast- ing samples respectively, and their viscosity and mechanical properties were tested. The results show that the smaller size of Al2O3 particle has greater effect on the viscosity of the casting system. When the addi- tion amount of micro-Al2O3 with different sizes is 300 phr, the casting system has the optimum mechani- cal properties, but the impact strength decreases obviously compared to the matrix resin. When the addi- tion amount of nano-Al2O3 is 2.5 phr, the impact strength of the casting system increases by 10% com- pared to the matrix resin. The micro-nano co-doped Al2O3 can further improve the mechanical properties of the casting system compared to the single component （micro or nano Al2O3）.
