The present invention relates to a polyimide-based resin composition comprising a thermoplastic polyimide having good solubility in general purpose organic solvents and a fibrous reinforcement such as carbon fiber, glass fiber, aromatic polyamide fiber and/or a potassium titanate fiber, a process for preparing the resin composition and an injection molded article of the resin composition, and further relates to a polyimide-based composite obtained by molding the above soluble and thermoplastic polyimide in combination with a fibrous reinforcement and a process for molding the same.
The polyimide used for the invention can be applied as a surface modifier for the fibrous reinforcement particularly in the form of a solution and provide a fibrous reinforcement having a surface modified with the above polyimide.
本发明涉及一种聚酰亚胺基树脂组合物,该组合物包括一种在通用有机溶剂中具有良好溶解性的热塑性聚酰亚胺和一种纤维状增强材料,如碳纤维、玻璃纤维、芳香族聚酰胺纤维和/或钛酸钾纤维;本发明还涉及一种制备该树脂组合物的工艺和一种用该树脂组合物注塑成型的制品;本发明还涉及一种通过将上述可溶性热塑性聚酰亚胺与纤维状增强材料组合成型而获得的聚酰亚胺基复合材料及其成型工艺。
用于本发明的聚酰亚胺可以作为纤维增强材料的表面改性剂,特别是以溶液的形式使用,并提供一种表面经上述聚酰亚胺改性的纤维增强材料。
