ABSTRACT: The main objective
of this research is to study the effect of fiber weight ratio and chemical
fiber modification on flexural properties of composites reinforced with Posidonia fiber. An unsaturated polyester matrix reinforced with untreated and
treated Posidonia fibers was
fabricated under various fiber weight ratios. Results showed that the combined
chemical treatment provided better mechanical properties of composites in
comparison with untreated fiber. The fiber weight ratio influenced the flexural
properties of composites. Indeed, a maximum value of flexural modulus was
observed for 10% fiber weight ratio for composites reinforced with treated
fibers. SEM photographs revealed a different
fracture surface between Posidonia fibers
reinforced polyester composites.
