The influence of the Ultem-1010 polyetherimide (PEI) on the physicomechanical properties of the ED-20 epoxy matrix and carbon-fiber-reinforced plastics (CFRP) based on the epoxy-polyetherimide binders is studied. It is shown that the introduction of PEI allows one to increase the impact strength and fracture toughness of the matrix 70 and 350%, respectively. The fracture toughness of the CFRP increases 40% with the rise in the PEI concentration. The correlation between the fracture toughness of the composites and their matrices has been established.

研究了 Ultem-1010 聚醚酰亚胺 (PEI) 对 ED-20 环氧树脂基体和基于环氧聚醚酰亚胺粘合剂的碳纤维增强塑料 (CFRP) 的物理机械性能的影响。结果表明，PEI 的引入可以使基体的冲击强度和断裂韧性分别提高 70% 和 350%。CFRP 的断裂韧性随着 PEI 浓度的增加而增加 40%。已经建立了复合材料的断裂韧性与其基体之间的相关性。
