Three types of carboxyl-functionalized multi-walled carbon nanotubes (MWCNTs) were used to manufacture MWCNT-modified laminates. The effects of the MWCNTs on the mode I interlaminar fracture toughness and the fracture propagation were investigated experimentally. Fractured surfaces were inspected with SEM micrographs to justify the effects of MWCNTs on the mode I fracture of the laminate. The short-thin MWCNTs in a weight ratio of 0.3% increases mode I interlaminar fracture resistance of the laminate by about 2 times. The effects of long-thin and long-thick MWCNTs are quite low. Polymer crazing is the most important mechanism to improve interlaminar fracture properties.

碳纳米管尺寸对 E-玻璃/环氧树脂纳米复合材料 I 型层间断裂行为的影响：静态载荷
三种类型的羧基官能化多壁碳纳米管 (MWCNT) 用于制造 MWCNT 改性层压板。实验研究了多壁碳纳米管对Ⅰ型层间断裂韧性和断裂扩展的影响。用 SEM 显微照片检查断裂表面，以证明 MWCNTs 对层压板 I 型断裂的影响。重量比为 0.3% 的短薄型 MWCNT 可使层压板的 I 型层间断裂抗力提高约 2 倍。长薄和长厚的多壁碳纳米管的影响是相当低的。聚合物龟裂是提高层间断裂性能的最重要机制。
