In the past few decades, research has been shifted from monolithic materials to fibre-reinforced polymeric materials. These composite materials now dominate the aerospace, leisure, automotive, construction and sporting industries. The natural fibres are biodegradable and they don’t cause any type of environmental pollution when compared with glass fibres. Fibre reinforced composites are prepared using Ecmalon 4411 resin, cobalt octate as an accelerator, methyl ethyl ketone peroxide (MEKP) as catalyst, sisal and tadi fibres. Different samples are prepared with varying number of fibres, % of casein, soaking time, % of alkali. Form hardness and tensile strengths, sisal fibres and tadi fibres reinforced composites are having high hardness compared with simple reinforced composites. The treated fibres reinforced composites with and without casein are having high hardness compared with untreated fibre reinforced composites. With an increase in the number of fibres, hardness of the composites also increased for treated and untreated fibres reinforced composites. With an increase in amount of casein, the hardness also increased for both treated and untreated fibre reinforced composites.

Abstract


In the past few decades, research has been shifted from monolithic materials to fibre-reinforced polymeric materials. These composite materials now dominate the aerospace, leisure, automotive, construction and sporting industries. The natural fibres are biodegradable and they don’t cause any type of environmental pollution when compared with glass fibres. Fibre reinforced composites are prepared using Ecmalon 4411 resin, cobalt octate as an accelerator, methyl ethyl ketone peroxide (MEKP) as catalyst, sisal and tadi fibres. Different samples are prepared with varying number of fibres, % of casein, soaking time, % of alkali. Form hardness and tensile strengths, sisal fibres and tadi fibres reinforced composites are having high hardness compared with simple reinforced composites. The treated fibres reinforced composites with and without casein are having high hardness compared with untreated fibre reinforced composites. With an increase in the number of fibres, hardness of the composites also increased for treated and untreated fibres reinforced composites. With an increase in amount of casein, the hardness also increased for both treated and untreated fibre reinforced composites.
