The interface performance of carbon fiber (CF) reinforced polymer composites (CFRPs) is one of the key factors that affect their properties. In order to improve the interface adhesion between CF and epoxy (EP), a green method is proposed. Carboxymethyl cellulose (CMC) and graphene oxide (GO) are introduced to the CF surface through the hydrogen bonds, and they can form high micromechanical interlocking composite architectures, which can enhance the micromechanical interaction in the interface of CF and EP. It is found that CMC and GO can significantly improve the interfacial shear strength (IFSS) and interlaminar shear strength (ILSS) of EP/CF composite. This means that it has great potential to improve the interface of CFRPs and strengthen their performance by natural cellulose fibers. This modification method does no harm to CF and is environmental friendliness, which lays a research foundation for using natural cellulose to enhance the interface performance of CFRPs.

碳纤维（CF）增强聚合物复合材料（CFRP）的界面性能是影响其性能的关键因素之一。为了提高CF和环氧树脂（EP）之间的界面粘合性，提出了一种绿色方法。羧甲基纤维素（CMC）和氧化石墨烯（GO）通过氢键引入CF表面，它们可以形成高微机械互锁的复合结构，从而增强CF和EP界面中的微机械相互作用。发现CMC和GO可以显着提高EP / CF复合材料的界面剪切强度（IFSS）和层间剪切强度（ILSS）。这意味着它有很大的潜力可以改善CFRP的界面并通过天然纤维素纤维增强其性能。
