Abstract :
In this study, the tensile and compressive behaviors of pure and hybrid composite laminates reinforced by
basalt–nylon bi-woven intra-ply fabrics were experimentally investigated. Epoxy resin was used as the matrix material.
The purpose of using this hybrid composite is to obtain superior characteristics by using the good strength property
of basalt fiber with the excellent toughness of nylon fiber. Five different types of woven fabric were used as
reinforcement with different volume percentages of nylon (0%, 25%, 33.3%, 50% and 100%). The effects of
nylon/basalt fiber content on tensile and compressive parameters were studied. In addition, the after failure visual
inspection and scanning electron microscopy (SEM) analysis was used to determine the extent and type of damage on
tested specimens. The results indicate that the tensile and compressive performances of these composites are strongly
affected by the nylon/basalt fiber content. Also, with a proper choice of fiber content, the nylon/basalt hybrid
composites can achieve mechanical properties comparable with the pure ones. The stress–strain curves, after failure
visual inspection and SEM analysis of tested specimens reveal that hybridization can prevent catastrophic and
complete failure. In hybrid composites, the basalt and nylon fibers cannot reach their maximum strength at the same
time and the progressive failure of the various fibers therefore occurred.
