Abstract

The current work aims to utilize sustainable natural fibers such as jute fiber in composite materials and a sustainable technology such as gamma (γ) irradiation to further treat the composites for their performance enrichment. First, synthetic glass fibers were hybridized to improve the performance of natural fiber composites (NFCs) with different stacking sequences. Jute fabrics were used as a natural fiber reinforcement and unsaturated polyester resin was employed as a thermoset polymer matrix. Composite laminates were manufactured by compression molding using a heat press machine. After hybridization, the mechanical properties and water resistance were improved compared to the neat NFCs (i.e., jute fiber composites, J0). The tensile strength, bending strength, tensile modulus, bending modulus, and impact strength were improved to 7–56, 5–53, 21–54, 27–69, and 199–387 %, respectively, than the J0. Further, gamma (γ) irradiation (5.0 kGy) was employed as a sustainable and chemical-free technology to treat the hybrid composite materials and improve the performance, and the optimum improvement was revealed for H3 (G₂J₄G₂) hybrid composites. For H3, the enhancement of tensile, bending and impact strength was revealed at approximately 28, 65 and 27 %, respectively, while the tensile and bending modulus were exhibited at approximately 27 and 71 %, respectively, compared to their non-irradiated composite ones. Further characterization of the composites was studied by FTIR (Fourier Transform Infrared) spectroscopy and SEM (Scanning Electron Microscopy) experimentation.

目前的工作旨在利用可持续的天然纤维（如黄麻纤维）和可持续的技术（如γ (γ)辐照）来进一步处理复合材料，以提高其性能。首先，对合成玻璃纤维进行杂化处理，以提高不同堆叠顺序的天然纤维复合材料的性能。以黄麻织物为天然增强纤维，以不饱和聚酯树脂为热固性聚合物基体。复合材料层压板是利用热压机进行压缩成型的。杂交后，与纯nfc（即黄麻纤维复合材料J0）相比，其力学性能和耐水性均有提高。拉伸强度、弯曲强度、拉伸模量、弯曲模量和冲击强度分别比J0提高了7-56、5-53、21-54、27-69和199-387 %。此外，采用γ (γ)辐照（5.0 kGy）作为一种可持续的、无化学物质的技术来处理杂化复合材料并提高其性能，并对H3 （G2J4G2）杂化复合材料进行了优化。与未辐照的复合材料相比，H3的拉伸、弯曲和冲击强度分别提高了约28%、65%和27% %，拉伸和弯曲模量分别提高了约27%和71% %。通过FTIR（傅里叶变换红外）光谱和SEM（扫描电子显微镜）实验进一步研究了复合材料的表征。
