Abstract

Presently composites made up of either both the binder and the reinforcing fibers are synthetic or either one of the material is natural or synthetic. In the present study coagulum (dried latex) of Euphorbia royleana has been used for replacing polyester resin as a natural binder in polyester banana fiber composite. The influence of different volume fraction of the coagulum in the composite is studied. It is observed that with the increase in the coagulum fraction, the flexural property of the polyester banana fiber composite increases. The flexural strength increase by 25% and flexural modulus by 15% at 40% of coagulum weight fraction. This study presents the possibility of preparation of composites using coagulum of Euphorbia latex. The developed composite may be used in partition walls, roof tiles, interior linings of automobiles, etc as wood substitute.
