摘要
Abstract
In order to investigate the mechanical properties of jute fiber nonwoven/unsaturated polyester resin composites, jute fiber nonwoven was prepared by needling process, then different composites of jute fi?ber were prepared by alkali treatment. The tensile bending properties of the composites were tested and the cross-section morphology of the composite was tested by scanning electron microscope. The influence of the mass fraction of jute fiber nonwoven and alkali treatment on the tensile strength and bending strength of the composites was analyzed. The experimental results showed that the mechanical properties of the unsaturated polyester resin were obviously enhanced by the jute fiber nonwoven. With the increasing of jute fiber mass fraction, the mechanical properties of the composites increased first and then decreased. When the mass ratio of jute fiber/resin was 20/80, the tensile strength and bending strength of the composites reached the maxi?mum. The tensile strength of the alkali treated jute fiber nonwoven reinforced composites was 41.78 MPa, and the bending strength was 59.03 MPa. After alkali treatment, the surface properties of jute fiber were im?proved, so that the interfacial bonding between jute fiber and polyester resin was improved, thus the mechani?cal properties of the composites were improved.关键词
