Abstract：In order to improve the mechanical properties of fiber composites for prefabricatedbuildings，four kinds of fiber composite laminates with diferent components were prepared byusing a twin-screw extrusion mechanism， the shear properties，bending properties and impact properties of Ti/CF/PA6、Ti/GB/CF/PA6、Ti/nano-CaCO 3 ／ CF/PA6 and Ti/GB/nano-CaCO 3 /CF/PA6 were compared and analyzed，and the fracture morphology was observed. The results showed that adding GB or nano-CaCO 3 to Ti/CF/PA6 alone，as well as the addition of GB and nano-CaCO 3 together，increased the shear strength of the composite，and the shear strength of the composite material was the highest when nano-CaCO 3 was added alone.Adding GB or nano- .cac03 to Ti/CF/PA6 alone reduced the flexural strength of the composite，while addition of nano- CaCO3 alone increased the flexural strength of composites. Adding GB or nano ⋅CaCO3 to Ti/CF/PA6 alone，as well as the addition of GB and nano- .cac03 together，increased the impact strength of the composite，and the impact strength of the composite material was the highest when GB and nano- CaCO3 were added together. After adding nano .cac03 alone or the combination of GB and nano- CaCO3 ， the composites have good mechanical properties and can be applied in prefabricated building structural materials.

装配式建筑是指把传统建造方式中的大量现场作业工作转移到工厂进行，在工厂加工制作好建筑用构件和配件（如楼板、墙板、楼梯、阳台等），运输到建筑施工现场，通过可靠的连接方式在现场装配安装而成的建筑。（剩余5756字）
