Abstract

An automotive application with renewable
sources as environmentally sustainable solution has been studied for weight
reduction. Hemp as non-woven natural fiber (NNF) and Polylactic acid (PLA)
non-woven fibers has been used to form continuous mat by needle-punch method.
This biobased mat structure was then hot formed to achieve good mechanical
properties. The composition of the fiber was 50:50 / NNF:PLA and the density of
the final sheet was 1300 gr/m², the final thickness of the
biocomposite after themoforming was 2.2 mm with 2.1 GPa Flexural Modulus and 17
MPa Tensile Strength and 2.3% elongation at break. In this study, the
mechanical performance of this biocomposite structure under water immersion,
40ºC and 80ºC was studied. The charpy impact strength was found 21kJ/m².
The major outcome of this study is replacing conventional reinforcement
materials with renewable sources which offers lower weight and tolerable
mechanical strengths.
