Temperature-frequency-dependent properties analysis of a bio-composite based on a new liquid thermoplastic resin reinforced with jute fibers

Abstract

One of the main current challenges in the development of materials is related to meet the structural industry demanding requirements and that are sustainable at the same time. This paper presents the composite mechanical characterization based on an innovative thermoplastic matrix reinforced by jute fibers. The composite was fabricated via VARTM (Vacuum Assisted Resin Transfer Molding) using jute fiber fabric in the 0/90° orientation. Several specimens were tested for uniaxial tension loading and their mechanical behavior was discussed. Also, the dynamic properties were evaluated with frequency variation and a master curve was constructed based on the WLF (Williams–Landel–Ferry) principle. Finally, fractographic evaluations of the fracture surfaces performed in a scanning electron microscope (SEM) confirm the quantitative characterization obtained from the mechanical analysis. The results obtained prove that the Jute/Elium® 150 composites can become a low-cost alternative methodology in the manufacture of more sustainable composites for the industry.
