Abstract In order to improve the interlaminar shear strength (ILSS) of glass fiber reinforced polymers (GFRPs), the fiber/matrix interface has been enriched via chemical robust bonds between glass fiber surface and carbon nanotubes (CNTs). Electrophoretic deposition (EPD) utilized to form a homogenous layer of CNTs on the chemically activated glass fibers. Initially, experimental studies on the electric field, suspension concentration and EPD duration conducted to find optimum EPD parameters for deposition. Then, various GFRP specimens manufactured to evaluate the effect of fiber's surface modification on ILSS of nanocomposites. Regarding most stable process and best quality of CNT deposition, the current density of EPD recorded between 0.5 and 1 mA/cm2. Field strength enhanced deposition mass around 8.5 times, but the concentration effect was around 5.5. Current density diagram was steady in stable processes and the first 3 min of EPD known as effective deposition time. The straightening influence of CNT deposition in composite's interface observed more effective than other treatment techniques. CNT deposition on surface of glass fibers improved the ILSS of GFRPs by 18.2% & 41.5% compared with simple and de-sized control samples, respectively.

碳纳米管电泳沉积在玻璃纹理上以改善聚合物复合材料界面的研究

摘要 为了提高玻璃纤维增​​强聚合物 (GFRPs) 的层间剪切强度 (ILSS)，通过玻璃纤维表面和碳纳米管 (CNTs) 之间的化学坚固键富集了纤维/基质界面。电泳沉积 (EPD) 用于在化学活化的玻璃纤维上形成均匀的 CNT 层。最初，对电场、悬浮液浓度和 EPD 持续时间进行了实验研究，以找到用于沉积的最佳 EPD 参数。然后，制造了各种 GFRP 样品以评估纤维表面改性对纳米复合材料的 ILSS 的影响。关于最稳定的过程和最好的 CNT 沉积质量，EPD 的电流密度记录在 0.5 到 1 mA/cm2 之间。场强增强沉积质量约 8.5 倍，但集中效应在5.5左右。电流密度图在稳定过程中稳定，EPD 的前 3 分钟称为有效沉积时间。观察到复合材料界面中 CNT 沉积的矫直影响比其他处理技术更有效。与简单和尺寸缩小的对照样品相比，玻璃纤维表面的 CNT 沉积使 GFRP 的 ILSS 分别提高了 18.2% 和 41.5%。
