ABSTRACT:
The hybrid composite of glass-epoxy is fabricated by the use of halloysite nanotubular particles by hand lay-up technique. Actually the direction of nano-clay particles may lead to agglomeration, to overcome this problem, the epoxy is need to be chemically treated. The chemical reaction of unsaturated polyester with the epoxy resin was carried out thermally in presence of benzyl peroxide-radical initiator and the resulting product was analyzed by X-Ray Diffractometer. Epoxy and unsaturated polyester toughened epoxy systems were further modified with 1, 2 and 3% (by wt) of Halloysite nano tubular (HNT) clay. Mainly this paper deals with the characterization and wear properties of epoxy polymer and glass fiber-reinforced epoxy-clay hybrid composites. Characterization is done with the help of X-Ray Diffraction and performance levels of the composite at different percentage of nano clay addition are observed. Under this wear test have been conducted in the Pin-on-disc type at different loads and time for different percentage composition of nano clay particles addition and respective changes are studied.
