Effect of chemical treatments on tensile properties and interfacial shear strength of unsaturated polyester/fan palm fibers

ABSTRACT

Surface treatment of fan palm fibers (FPFs) was investigated as a means of improving fiber tensile strength (FTS) and interfacial shear strength (IFSS) of unsaturated polyester (UPR)/FPFs samples. The fibers were treated with sodium hydroxide, silane, and a combined sodium hydroxide and silane. FT-IR spectra and SEM observation indicated the removal of hemicellulose and lignin components after chemical treatments. The alkaline treatment of FPF resulted in the highest tensile strength of 816 MPa. The interfacial shear strength of FPF/UPR samples was increased for all treated FPF. The highest IFSS (4.1 MPa) was obtained for the alkaline-treated FPF/UPR sample.

摘要

扇形棕榈纤维表面处理（FPFS）进行了研究，为提高纤维抗拉强度的一种手段（FTS）和界面剪切强度（IFSS）不饱和聚酯树脂（UPR）/FPFs样品。用氢氧化钠、硅烷和氢氧化钠和硅烷的混合物对纤维进行处理。FT-IR光谱和扫描电镜观察表明，化学处理后去除半纤维素和木质素组分。FPF碱处理后的拉伸强度最高为816兆帕。界面剪切强度为FPF /不饱和聚酯树脂样品处理以增加。最高的IFSS（4.1 MPa）是得到的碱处理的FPF和UPR的样本。
