Effect of CaCo3 for woven Hemp flax Reinforced with wire mesh for Automobile Applications

Abstract

Natural fibre-reinforced polymeric composites utility is increased by the automotive industries due to their advantages such as recyclability, cost- effectiveness, light weight, high strength, rigidity and ecological production.  The natural polymeric fibre-hybrid composite overcomes the concerns of the mechanical properties of mono-material fibre-reinforced composites.

This investigation involves using Hemp (H), and flax (F) fibres in the Hybrid Natural Fibre Polymer (HNFPC) composites for different applications. Natural Fibres Wire Mesh Composite (NFWMC) plates were fabricated using woven A/H/F along with Stainless Steel Wire Mesh (SSWM), aluminium wire mesh (ALWM) and copper wire mesh (CUWM) of samples were fabricated using hand-layup and through compression moulding techniques. The Experimental trial-I samples were prepared with A/H, F/H, A/F and A/H/F combinations along with LY556 and HY951. In trial-II the samples were prepared by adding CaSO₃ in various weight ratios (1%, 3%, 5% and 7 %). The optimum results were obtained for sample with 5% of CaCO₃ addition, and hence the samples uses in the first trial combinations with 5% of BaSO₄were preferred for trial-III. Finally, along with 5% of BaSO₄the experimental trial-IV samples were fabricated using stainless steel, aluminium and copper wire mesh.

The mechanical properties of the composite materials were determined by the tensile, flexural, impact and hardness properties. The Visco-elastic properties were estimated by the Dynamic Mechanical Analysis (DMA).
