Ultrahigh-strength continuous fiber reinforced liquid crystal polymer composite material and preparation method thereof

The invention discloses an ultrahigh-strength continuous fiber reinforced liquid crystal polymer composite material and a preparation method thereof. After the fiber cloth and the liquid crystal polymer prepolymer powder are subjected to hot static pressure molding, the mechanical property of the composite material is improved through a heat treatment process, the tensile strength of the obtained continuous fiber reinforced liquid crystal polymer composite material is larger than 1800 MPa, and the continuous fiber reinforced liquid crystal polymer composite material can be used for large structural parts. 本发明公开了一种超高强度连续纤维增强的液晶聚合物复合材料及其制备方法。使用纤维布与液晶聚合物预聚物粉末热静压成型后，再通过热处理工艺提升复合材料的力学性能，得到的连续纤维增强的液晶聚合物复合材料拉伸强度大于1800MPa，可用于大型结构件。
