摘　　要：为解决深部充填体固结效果差、强度低、易开裂的技术难题,研究通过调整玻璃纤维含量和优化水泥基混合物的配比,使复合材料可以应用在房屋墙体结构中,结果显示,PA66添加量为10wt%时,复合材料可展现出最佳的流动性和加工性能。在力学性能方面,虽然拉伸强度和拉伸模量随PA66添加量的增加而降低,但弯曲强度却呈现增强趋势,表明PA66的添加量对提高复合材料的弯曲性能具有积极作用,该结构体系具有装配化程度高、安全裕度大、抗侧刚度和抗侧承载力强等特点。In order to solve the technical problems of poor consolidation effect,low strength,and easy cracking of deep filling materials,a study was conducted by adjusting the glass fiber content and optimizing the proportion of cement-based mixtures,so that composite materials can be applied in building wall structures.The results showed that when the amount of PA66 added was 10wt%,the composite material could exhibit the best fluidity and processing performance.In terms of mechanical properties,although the tensile strength and tensile modulus decrease with the increase of PA66 addition,the bending strength shows an increasing trend,indicating that the addition of PA66 has a positive effect on improving the bending performance of composite materials.This structural system has the characteristics of high assembly degree,large safety margin,strong lateral stiffness and lateral bearing capacity.
