ABSTRACT

Viscose rayon filaments were used as reinforcement in the chitosan matrix (dissolved in acetic acid) to create a truly green composite. Unidirectional composites with different weights of viscose rayon filament were fabricated. The composite material was characterized by tensile strength, FTIR, TGA, XRD, and SEM. The tensile strength of the biocomposite increased (43.81%), and elongation % decreased (11.42%) with an increase in reinforcement loading. FTIR spectra of biocomposites confirmed strong hydrogen bonding between chitosan and hydroxyl groups of viscose rayon. The SEM micrograph indicated that the viscose rayon filament was fully surrounded by the matrix, and hence a strong composite was fabricated.

摘要

粘胶人造丝长丝用作壳聚糖基质（溶于乙酸）中的增强材料，以形成真正的绿色复合材料。制备了具有不同重量粘胶人造丝长丝的单向复合材料。通过拉伸强度、FTIR、TGA、XRD和SEM对复合材料进行了表征。随着钢筋载荷的增加，生物复合材料的拉伸强度增加（43.81%），伸长率下降（11.42%）。生物复合材料的 FTIR 光谱证实壳聚糖与粘胶人造丝的羟基之间存在强氢键。SEM 显微照片表明，粘胶人造丝长丝完全被基体包围，因此制成了坚固的复合材料。
