Abstract

This study investigates the mechanical properties of nonwoven hybrid composites made from recycled cotton/polyethylene terephthalate (PET) with various fiber weight percentages (100/0, 0/100, 75/25, 60/40, 50/70, 60/40, and 25/75). The multilayered nonwoven carded webs are manufactured by the carding machine, while the manual lay-up technique is used to fabricate nonwoven-reinforced composites. Their tensile, flexural, and impact properties and microstructure are then examined. It is found that the tensile modulus and strength increase with the increase in cotton, while the impact strength improves with the increase in PET. The composite of 75% cotton/25% PET offers 92.13% and 67.87% higher tensile modulus and strength than the composite of 25% cotton/75% PET; however, the composite of 25% cotton/75% PET shows 83.09% and 36.22% higher flexural modulus and strength, and 187% more impact strength, respectively, than the composite of 75% cotton/25% PET. The outcome of this study indicates that nonwoven composites with higher contents of recycled cotton can potentially be applied in building and construction sectors where substantial tensile strength is necessary, while composites with comparatively higher contents of recycled PET may be used for various potential applications (e.g., helmets, surfboards, and automotive interiors) where significant flexural and impact strengths are required.

再生棉/ PET 纤维增强聚酯混合复合材料无纺布机械特性的研究
本研究探讨了不同纤维重量百分比(100/0、0/100、75/25、60/40、50/70、60/40 和 25/75)的回收棉/聚对苯二甲酸乙二醇酯(PET)无纺布混合复合材料的机械性能。多层无纺布梳理网由梳理机制造,而手工铺层技术则用于制造无纺布增强复合材料。然后对其拉伸、弯曲和冲击性能以及微观结构进行了研究。结果发现,拉伸模量和强度随着棉的增加而增加,而冲击强度则随着 PET 的增加而提高。75% 棉/25% PET 复合材料的拉伸模量和强度分别比 25% 棉/75% PET 复合材料高 92.13% 和 67.87%;而 25% 棉/75% PET 复合材料的弯曲模量和强度分别比 75% 棉/25% PET 复合材料高 83.09% 和 36.22%,冲击强度则高 187%。研究结果表明,再生棉含量较高的无纺布复合材料有可能应用于需要较大拉伸强度的建筑和构造领域,而再生 PET 含量相对较高的复合材料则有可能应用于各种需要较大弯曲和冲击强度的领域(如头盔、冲浪板和汽车内饰)。
