In addition to this we studied the effect of chemicaltreatment on the properties of fiber . In the last,we prepared the composite by graft the polymeric matrix by treated and untreated fiber. Among the test used in order to indentify the extent of the effect of chemical treatment we recall test FTIR.and flexion test.frluffa.cellulose.alkli treatment .polyester.compositeThesis
