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. Key words：prefabricated buildings；fiber composite materials；particle enhancement；mechanical properties；fracture morphology
裝配式建筑是指把傳統(tǒng)建造方式中的大量現場作業(yè)工作轉移到工廠進行，在工廠加工制作好建筑用構件和配件（如樓板、墻板、樓梯、陽臺等），運輸到建筑施工現場，通過可靠的連接方式在現場裝配安裝而成的建筑。（剩余5756字）
