composites materials have been widely used in engineering fields like civil,
automotive, and aerospace industry, due to their high light weight, strength, and longue life
expectancy. In the present study, biocomposites were prepared from thermoset resins named
unsatured Polyester (UP) as matrix, and sisal ( Agave fourcroydes) as natural reinforcing fibers,
requires a strong adhesion between fiber and matrix., biocomposites were prepared by putting
small drops of synthetic matrix (UP) on the untreated and 3% NaOH alkali treated sisal fibers. The
mechanical properties of the sisal fibers were studied by tensile strength tests, where mechanical
properties of biocomposites prepared were characterized in terms of microbond tests, by
estimating the values of external loads at moment of crack initiation. The results of mechanical
properties showed a significant improvement for tensile strength and young's modulus was
observed for treated sisal fiber, also a good interfacial adhesion with treated sisal fibers and matrix.
