Mechanical behavior of Fe-based amorphous ribbons-glass fibers reinforced hybrid composites

Hybrid composites reinforced with Fe-based amorphous ribbons and glass fibers were manufactured and mechanical properties were studied. Influences of surface treatment and heat treatment of ribbons on their properties were investigated. The failure mechanism of the hybrid composite was analyzed. The surface of the ribbon was roughened and its surface energy was increased, the bonding strength between ribbon and different resins was increased by surface treatment, while axial tensile properties of the ribbon did not change a lot. The longitudinal elastic modulus obeys the rule of mixture while the transverse tensile strength and modulus are mainly contributed by amorphous ribbons. Delamination between fiber layer and ribbon layer as well as fracture of fiber in the compressed side was observed in the flexure and interlaminar shear specimens.
