Experimental investigation on impact, compressive and losipescu shear strength of glass/flax hybrid composites for automotive application

In Current scenario, polymer hybrid composites are extensively utilized as substitutes for traditional materials in various engineering applications. The hybridization technique for manufacturing composite materials through the integration of organic and synthetic fibres is experiencing significant growth in industries such as aerospace, automotive, military, and structural applications. These manufactured composites possess notable attributes such as eco-friendliness and sustainability. Due to the high tensile strength and amazing antistatic properties, flax fibre is considered to hybrid with glass fibre and forms a hybrid material with polyester resin. In this investigation, woven flax fibre was treated with alkaline solution and hybridized with woven glass fibre with polyester resin through vacuum bag moulding process. Three types of glass/flax hybrid composites are prepared to analyse the impact strength, compressive strength and shear strength are tested as per the various ASTM standard. Experimental results showed that the developed glass/flax hybrid composites achieved enhanced impact strength, compression strength and shear strength performance compared with flax reinforced epoxy composite.
