The effect of the combined chemical treatment of sisal fibres through the subsequent processes of mercerisation (alkali treatment), then silane treatment and eventually acid hydrolysis, on sisal fibre was investigated. The effect of the treated fibres on the impact toughness and hardness of their composites with epoxy resin was also studied. Scanning electron microscopy of the surfaces of the treated and untreated fibres showed that the chemical treatment processes enhanced the removal of surface impurities and therefore increased the roughness of the surfaces of the fibres. This avails an increased surface area for interlocking with matrix and is, therefore, expected to enhance adhesion of the two. The treated fibre reinforced composites were observed to have higher values of impact toughness and hardness than the untreated fibre reinforced composites. These higher values were attributed to better interfacial bonding due to better mechanical interlocking between the treated fibres and epoxy resin arising from the increased roughness of the treated fibres.


Regular Fiber fortified composites discovers place in numerous applications as they have the benefits of being light, solid, modest and progressively ecological well disposed. This investigation planned to decide the impact of antacid treatment on normal fiber and its effect on the warmth diversion conduct of the regular and glass fiber fortified cross breed composites ,in this work two kind of half and half composite are made with glass, sisal and flax fiber ,the crossover strengthened composite covers were manufactured by hand lay-up technique. Examples are cut from the manufactured cover and their warmth diversion conduct was tried by ASTM D648 benchmarks. From the outcome it is comprehended that the basic treatment has improved the warmth avoidance withstanding limit of flax/glass half and half composite and don't have much impact on sisal/glass mixture composite.
