The invention discloses a preparation method of a long-carbon-chain polyamide composite material and the composite material. The composite material is prepared from polyamide resin and pre-oriented functional polyamide fibers through melt blending. The pre-oriented homogeneous special-shaped high-temperature-resistant polyamide fiber is used as a reinforcing agent, and the chemical composition ofthe reinforcing agent is similar to that of a polyamide resin matrix so that the compatibility between the fiber and the polyamide resin matrix is improved, the interfacial force between the fiber andthe polyamide resin matrix is enhanced and the mechanical property of the composite material is improved. 本发明公开了一种长碳链聚酰胺复合材料的制备方法及复合材料，所述复合材料由聚酰胺树脂和预取向的功能聚酰胺纤维经熔融共混制得。本发明是将预取向的同质异形的耐高温聚酰胺纤维作为增强剂，其与聚酰胺树脂基体相近的化学组成，改善了纤维与聚酰胺树脂基体之间的相容性，增强了两者之间的界面作用力，提高了复合材料的力学性能。
