Visco-elastic properties and thermal analysis of corchorus/elastane yarn–reinforced biocomposites

As a result of their lower weight and higher strength-to-weight ratio, composite materials are gaining popularity in the automotive sector. Due to their superior mechanical qualities, synthetic hybrid fibres are also utilised in the automotive industry. Still, natural/synthetic hybrid fibres are gradually replacing the synthetic fibre composite to lessen the world’s reliance on manufactured materials. Traditional hand layup is used to create three different composite laminates in this study: natural, synthetic and natural/synthetic fibre. The three laminates use jute fibre (corchorus), spandex (elastane) fibre and jute/spandex interwoven fibres as reinforcements; the weight fraction of reinforcement is 45%; the epoxy matrix is 50%, and granite nanoparticles are 5%; the dynamical effect and thermal stability of the hybrid composite are analysed and quantified by changing the weight fraction of reinforcement in the blend. The hybridisation of jute fibre and spandex fibre–interlaced mat loading (jute/spandex) achieved a maximum storage modulus of 2300 MPa at the glass transition temperature, along with improved results in visco-elastic characteristics and 8 per cent greater, 431 °C of thermal stability compared to samples A and B. After composite laminates were fabricated, their layer adhesion and surface finishing were characterised by scanning electron microscopy (SEM).
