Abstract

In the majority of technological applications, particularly in automotive and building materials, natural fibre-reinforced composites are now more common. Natural fibre developments have seen a tremendous rise in demand recently. As a filler material, Snail Shell Powder was utilized in the current work to evaluate the mechanical and thermal characteristics of hybrid reinforced composites constructed from natural fibres such as basalt, pineapple, and bamboo. Snail shell powder weighed six grams in each specimen. Composites 1 (Basalt), 2 (Pineapple), 3, (Bamboo), 4, (Pineapple + Basalt), 5, (Bamboo + Basalt), 6, and 7 (Pineapple + Basalt + Bamboo) were produced using the hand layup technique. Tensile and flexural tests were done to assess mechanical properties. To test thermal properties, methods including thermogravimetric analysis (TGA) were used. The Composite 1 (Basalt) material has outstanding qualities, with tensile strengths of up to 152.22 MPa and flexural strengths of up to 186.28 MPa. As the temperature varied during the TGA thermal test on Composites 1, 2, 3, and 7, the properties of the materials were examined. Scanning electron microscopy (SEM) is used to do morphological analysis on composites 1, 2, 3, and 7 in order to look into the fracture behaviours and fibre pull-out of the samples.
