Abstract

The sustainable processing of recycled products requires veritable testing during quality control for commercial application. In this research work, mechanical (ASTM D3039), compression (ASTM D5467) and impact (ASTM A370) are utilized to observe the usability, diversity, and suitability of the developed polypropylene-postconsumer cotton fibers (PP-PCCF) composites for industrial applications. The cotton waste was ground using a grinding machine. The ground fibers were introduced to manufacture composites from 0 to 40% fiber loading variations. The fine cotton fibers and synthesized composites were characterized by scanning electron microscope before and after mechanical testing. The fiber length, diameter and area were in the range of 2.5 mm–5.5 mm, 12.5 μm–22 μm and 200.15 μm2–250.50 μm2, respectively. The engineering and design values were tensile strength (31.16 MPa–22.77 MPa), breaking strength (26.69 MPa–22.77 MPa), modulus of elasticity (2223.79 MPa–2770.77 MPa), and extension (17.48–3.21). Similarly, flexural strength, modulus, energy, and fracture force are also enhanced with an increase in fiber loading. The impact energies of pure polypropylene and PP-PCCF composites (with 10, 30, and 40% PCCF contents) were 50 kJ/m2, 48 kJ/m2, 43 kJ/m2, and 58 kJ/m2. The micrographs of PP-PCCF composites prove that the density of voids is enhanced with an increase in fiber contents. The PP-PCCF composites with 0%–30% fiber loadings showed minimum defects and were observed to be suitable for structural applications. On the other hand, the PP-PCCF composites with 30%–40% fiber loading are acceptable for environmental applications.

商业应用再生聚丙烯-棉复合材料的试验力学分析
回收产品的可持续加工需要在商业应用的质量控制过程中进行真正的测试。在这项研究工作中,利用机械(ASTM D3039)、压缩(ASTM D5467)和冲击(ASTM A370)来观察所开发的聚丙烯消费后棉纤维(PP-PCCF)复合材料在工业应用中的可用性、多样性和适用性。棉花废料是用研磨机研磨的。引入研磨纤维来制造纤维负载变化为0至40%的复合材料。在力学测试前后,用扫描电子显微镜对棉纤维及其合成的复合材料进行了表征。纤维长度、直径和面积分别在2.5 mm–5.5 mm、12.5μm–22μm和200.15μm–250.50μm之间。工程和设计值分别为抗拉强度(31.16 MPa–22.77 MPa)、断裂强度(26.69 MPa–22.77MPa)、弹性模量(2223.79 MPa–2770.77 MPa)和伸长率(17.48–3.21)。同样,弯曲强度、模量、能量和断裂力也随着纤维载荷的增加而增强。纯聚丙烯和PP-PCCF复合材料(PCCF含量分别为10%、30%和40%)的冲击能分别为50kJ/m2、48kJ/m2、43kJ/m2和58kJ/m2。PP-PCCF复合材料的显微照片证明,随着纤维含量的增加,空隙密度增加。纤维负载量为0%-30%的PP-PCCF复合材料显示出最小的缺陷,并被观察到适用于结构应用。另一方面,纤维负载量为30%-40%的PP-PCCF复合材料可用于环境应用。
