Enhancement of Mechanical Properties in Glass-Fiber Woven Reinforced Hybrid Composites for Aerospace Applications: An Empirical Investigation

作者： Abeer   Farouk   Al   Attar     Hussein   Alaa   Jaber     Ammar   Mousa   Hasan   来源： Revue des Composites et des Matériaux Avancés-Journal of Composite and Advanced Materials​ 年份： 2023 文献类型 ： 期刊 关键词： glass   fiber   E   woven   mechanical   Al2O3   red   (ANOVA)   hybrid   variance   Analysis   composite   of   kaolin   properties  

描述： This experimental study aims to create innovative hybrid composites (HCs) for aerospace applications using the hand lay-up technique. Different volume fractions (Vf%) of distinctive natural (white clay (W) and red clay (R)) and synthetic (alumina (A) and woven glass fibers (E-GFW) reinforcing unsaturated polyester (UP). The mechanical and physical characterizations of these innovative HCs were estimated according to the American Society for Testing and Materials (ASTM) standards. The findings show that adding more white clay, red clay, and alumina to the HCs makes a big difference in improving their mechanical properties, such as Hardness Shore D (HSD), True Tensile Strength (Ttσ), Impact Strength (iσ), and Fracture Toughness (Kc). Analysis of variance (ANOVA) revealed noteworthy variations in the assessed parameters, emphasizing the potential suitability of these materials for aeronautical applications. This research contributes to the ongoing progress in material engineering, specifically in enhancing the mechanical resilience of composites utilized in the aerospace industry.
