Processing, thermal and mechanical properties of composite laminates with natural fibers prepregs

This work manufactured prepregs by impregnating discontinuous curaua fibers with B-stage epoxy resin. The prepreg layers were then stacked to produce laminates hot compression. Alkaline treatments previously applied the improve their interface polymer matrix. Then, and final composites studied regarding thermal, dynamic mechanical, morphological behavior. promoted defibrillation removing lignin hemicellulose from fibers, which allowed better impregnation of treated In general, that used exhibited largest storage modulus in glassy region. mechanical results showed produced presented a highest tensile flexural resistance than those untreated neat NaOH-treated curaua/epoxy laminate high strength (56.2 MPa) (3.3 GPa). Overall, fracture morphology indicated fiber adhesion for composites. demonstrate natural can be successfully present proper physical behavior components.
