摘　　要：研究了氯氧镁凝胶/砂增强复合材料配方各组分对弯曲性能的影响。实验结果表明,随着砂料含量的增加,材料的弯曲强度和弯曲模量也相应增加;粒径小的砂料具有更好的增强效果,也能使材料的弯曲性能提高;对于砂料含量为60%的复合材料,其弯曲强度提高了40.1%,而其弯曲模量则提高了132.1%。The effects of the variations of the ingredients of the sand reinforced magnesium oxychloride gelatin composites on their flexural properties have been investigated. Experimental results showed that the increase of the addition amount of the sand could significantly raise both the flexural strength and the flexural modulus of the composites. Small size of the grains of sand can give the materials good reinforcement with the raise of the flexural properties. Composite with 60% of mass fraction of sand raised its flexural strength to 40.1% and the flexural modulus up to 132.1% compared with the blank test.
