Abstract Cellulose nanofiber (CNF) is high strength and lightweight, additionally, it is produced by sustainable natural resources such as wood. Therefore, it has been reported the mechanical properties of CFRP can be improved by dispersing CNF in the matrix. However, as CNF is hydrophilic, a hydrophobic treatment was applied in many previous studies. For efficient CFRP manufacturing, the authors have developed an electrochemical resin molding method by using aqueous electro-activated deposition which contains the polymer having an epoxy group. In this method, the carbon fiber fabric is immersed in the electro-activated deposition solution and energized, epoxy resin is precipitated around the carbon fiber and impregnated. In this study, shortly after electro-activated deposition, CNF without a hydrophobic treatment was applied to the surface of the resin-impregnated carbon fiber fabric. The mechanical properties of CFRP could be enhanced, and optimum weight fraction of CNF was revealed.

使用电活化沉积树脂成型法制造的碳纤维增强塑料的机械性能增强，应用无疏水处理的碳纤维

摘要 纤维素纳米纤维（CNF）强度高、重量轻，另外，它是由木材等可持续自然资源生产的。因此，据报道可以通过在基体中分散 CNF 来改善 CFRP 的机械性能。然而，由于 CNF 是亲水的，因此在许多以前的研究中应用了疏水处理。为了有效地制造 CFRP，作者开发了一种电化学树脂成型方法，该方法使用含水电激活沉积，其中包含具有环氧基的聚合物。在该方法中，将碳纤维织物浸入电活化沉积溶液中并通电，环氧树脂在碳纤维周围沉淀并浸渍。在这项研究中，在电激活沉积后不久，未经疏水处理的 CNF 被施加到树脂浸渍的碳纤维织物的表面。CFRP 的力学性能可以得到提高，并揭示了 CNF 的最佳重量分数。
