Development of Jute Fabric for Jute-Polyester Biocomposite considering Structure–Property Relationship

ABSTRACT

An attempt has been made to investigate the effect of jute fabric structure, e.g., woven (plain, twill, matte), knitted, and nonwoven (parallel, cross, random laid) as reinforcement, on properties of the jute-polyester composite. The composite sheet was prepared with unsaturated polyester resin and jute fabric by hand lay-up technique using a male-female type mold. Tensile, flexural, impact, and water absorption properties of composite were measured. With the best composite based on properties, compression, shear, and hardness were also measured. Random laid nonwoven shows maximum tensile and impact strength but twill fabric produces maximum flexural strength. Matte fabric shows higher strength and lower elongation among the woven fabrics under experiment. Impact resistance and water absorption of composite from multi-layer fabric are higher compared to single-layer fabric. Composite from twill fabric shows maximum water penetration, whereas random laid nonwoven shows the lowest in similar condition. The study reveals that composite from knitted fabric is better than woven fabric but inferior to nonwoven fabric so far as mechanical properties are concerned. So, multi-layered needle punched jute nonwoven fabric from random laid web is recommended for jute-polyester composite, where higher tensile and impact strength with lower water absorption is required.

摘要

研究了黄麻织物（平纹、斜纹、哑光）、针织物和非织造布（平行、交叉、无规布）作为增强体对黄麻-聚酯复合材料性能的影响. 以不饱和聚酯树脂和黄麻织物为原料，采用男女模手糊工艺制备了复合板. 测试了复合材料的拉伸、弯曲、冲击和吸水性能. 根据性能选择最佳复合材料，并对其压缩、剪切和硬度进行了测试. 无规铺设的非织造布显示出最大的拉伸和冲击强度，而斜纹织物产生最大的弯曲强度. 在实验机织物中，哑光织物具有较高的强度和较低的伸长率。多层织物复合材料的抗冲击性能和吸水率均高于单层织物. 斜纹织物的复合材料具有最大的水渗透性，而无规铺设的无纺布在类似条件下的渗透性最低. 研究表明，针织物复合材料的力学性能优于机织物，但低于非织造布. 建议多层无纺布的抗冲击强度较低，采用多层针刺非织造布，以提高复合材料的抗冲击强度.
