Abstract Recently, the significant development and advantages of bioactive natural composite materials have been employed in modern engineering constructions, aerospace, packing industries, automotive fields, and more. The fiber materials are derived from natural plant materials (e.g., coir, jute, and bamboo) and animal waste products which show excellent physico–chemical, thermal, and mechanical properties compared to man–made fibers. In this study, the replacement of man–made fiber materials with polymer matrix composites using natural waste chicken feather fiber (CFF) based reinforced lightweight epoxy hybrid composite materials were prepared for the development of a prototype bike silencer. The hybrid composites were prepared from epoxy resin reinforced with synthetic inorganic glass fibers (GF) and natural organic CFFs (with 5, 10, and 20 % composition) together with 3 % of nano–hydroxyapatite (nHA) as a catalytic filler. The 3D modeling, design, and fabrication of a prototype bike silencer were undertaken, using Suzuki Samurai as a reference model specimen. The hybrid 82 G F/15CFF/3HA composite material showed optimum tensile strength and yield strength values of 167.00 and 58.10 MPa, respectively. The observed von–Mises stress, maximum displacement, Young’s modulus, and Poisson’s ratio values were 6.9260 MPa, 0.8661 mm, 13.90 GPa, and 0.39, respectively. Further, the presence of voids in the hybrid 82 G F/15CFF/3nHA composite bike silencer showed higher absorption capacity with effective reduction of toxic CO, HC, O2, and CO2 pollutants as well as remarkable heat releasing capacity, as compared to the steel silencer. The fabricated hybrid 82 G F/15CFF/3nHA composite material may effectively be utilized for the development of renewable, eco–friendly biocomposites with exceptional performances.

使用混合玻璃和鸡毛纤维/羟基磷灰石增强环氧树脂复合材料制造和建模原型自行车消音器

摘要 近年来，生物活性天然复合材料的显着发展和优势已被应用于现代工程建设、航空航天、包装工业、汽车领域等领域。纤维材料来源于天然植物材料（如椰壳纤维、黄麻和竹子）和动物废物，与人造纤维相比，这些材料具有优异的物理化学、热学和机械性能。在这项研究中，使用天然废鸡毛纤维（CFF）基增强轻质环氧混合复合材料用聚合物基复合材料替代人造纤维材料，以开发原型自行车消音器。混合复合材料由合成无机玻璃纤维 (GF) 增强的环氧树脂和天然有机 CFFs (5, 10, 和 20% 的成分）以及 3% 的纳米羟基磷灰石 (nHA) 作为催化填料。使用铃木武士作为参考模型样本，进行了原型自行车消音器的 3D 建模、设计和制造。混合 82 G F/15CFF/3HA 复合材料的最佳拉伸强度和屈服强度值分别为 167.00 和 58.10 MPa。观察到的 von-Mises 应力、最大位移、杨氏模量和泊松比值分别为 6.9260 MPa、0.8661 mm、13.90 GPa 和 0.39。此外，与钢制消音器相比，混合 82 GF/15CFF/3nHA 复合材料自行车消音器中存在的空隙显示出更高的吸收能力，有效减少有毒 CO、HC、O2 和 CO2 污染物以及显着的散热能力.
