ABSTRACT The focus of this study is to identify the best surface treatment to maximize the bonding between a commercially available Dyneema® fiber and a high-density polyethylene matrix. The effect of a new sol-gel derived organic-inorganic hybrid coating on interfacial shear strength (IFSS) was compared with that of oxygen plasma and chromic acid treatments identified by previous studies. The treated fiber surfaces were examined using Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FT-IR), X-ray Photoelectron Spectroscopy (XPS) to support the analysis using IFSS. The fiber surface became rough after the treatments, which increased with treatment time. The XPS spectra revealed a similar change in surface chemistry of fibers for sol-gel treatment for 1 min and plasma treatment for 6 min, which resulted in a similar enhancement in IFSS when compared to untreated fiber. Chromic acid treatment for 1 min resulted in the largest change in the percentage of carbon- and oxygen-containing groups on the treated surface when compared to the untreated surface as well as maximum enhancement of the IFSS over untreated fiber.

纤维表面处理对 Dyneema® 纤维与 HDPE 基体结合强度的影响

摘要 本研究的重点是确定最佳表面处理方法，以最大限度地提高市售 Dyneema® 纤维和高密度聚乙烯基体之间的粘合。将新的溶胶-凝胶衍生的有机-无机混合涂层对界面剪切强度 (IFSS) 的影响与先前研究确定的氧等离子体和铬酸处理的影响进行了比较。使用扫描电子显微镜 (SEM)、傅立叶变换红外光谱 (FT-IR)、X 射线光电子光谱 (XPS) 检查处理过的纤维表面，以支持使用 IFSS 的分析。处理后纤维表面变得粗糙，并随着处理时间的增加而增加。XPS 光谱显示，溶胶-凝胶处理 1 分钟和等离子体处理 6 分钟后，纤维的表面化学变化相似，与未处理的纤维相比，这导致 IFSS 类似的增强。与未处理的表面相比，铬酸处理 1 分钟导致处理过的表面上含碳和含氧基团的百分比变化最大，并且与未处理的纤维相比，IFSS 的增强最大。
