将热压成型和薄膜叠层两种制备高分子复合材料的基本工艺相结合，制备了聚酰胺6（PA 6）高分子复合材料。起始材料为PA 6高强度纱线（增强材料）和通过熔融淬火制备的PA 6膜（基质），两者预期是PA 6的两种主要多晶型改性，因此它们的熔融温度不同。所制备的单一聚合物复合材料的特征在于层状结构，并且由于良好的润湿-拉伸模量而显示出上级机械性能，与各向同性基质膜相比，其提高了200%，并且极限拉伸强度提高了300-400%。通过Sb（2）O（3）作为催化剂促进的反式反应改善了界面结合力。
Combining the two basic techniques used for the preparation of single polymer composites (SPCs), hot compaction and film stacking, a polyamide 6 (PA 6) single polymer composite was manufactured. The starting materials were PA 6 high tenacity yarn (reinforcement) and PA 6 film prepared via melt quenching (matrix), both expected to be the two principal polymorphic modifications of PA 6 and thus differing in their melting temperatures. The prepared single polymer composite is characterized by a layered structure and shows superior mechanical properties due to the good wetting-tensile modulus is improved by 200% and the ultimate tensile strength - by 300-400% as compared to the isotropic matrix film. Improvement of the interfacial adhesion via transreactions promoted by Sb(2)O(3) as a catalyst was also undertaken.
