Composite material for geogrid and preparation method thereof
The invention relates to the technical field of geogrids, in particular to a composite material for geogrids and a preparation method thereof.The preparation method includes the steps that high-modulus and high-brittleness high-performance fibers and improved BOP fibers are subjected to three-dimensional weaving, and a biaxial reinforced weft-knitted spacer fabric is prepared to serve as a prefabricated fabric; the ultrahigh relative molecular weight polyethylene, the linear low density polyethylene melt mixture and the high density polyethylene are compounded to serve as a reinforcing material to be completely filled, the reinforcing material and the prefabricated fabric are fully permeated into one, the deformation resistance under the condition of long-term load is achieved, and it is guaranteed that the performance of the product can be kept for a long time.
本发明涉及土工格栅技术领域，具体涉及一种土工格栅用复合材料及其制备方法，本发明采用高模高脆的高性能纤维和改进BOP纤维进行三维编织制得一种双轴向增强纬编间隔织物作为预制织物，并将超高相对分子质量聚乙烯、线性低密度聚乙烯熔混料与高密度聚乙烯复合作为增强材料完全填充，与预制织物充分渗透合二为一，具备在长期荷载的情况下抵抗变形的能力，保证产品能够长期保持性能。
