Hybrid fabrics for composites reinforcement

In this study, experimental investigations are carried out to check the thermal and mechanical behavior of woven Basalt/PET and Basalt/PP fiber hybrid woven fabric epoxy composite laminates. Three types of weaves are used for all hybrid structures. Fabricated composite samples are subjected to mechanical and thermal characterization. Results are discussed in terms of fiber effect, weave geometry and the resin effect. The results reveal that the hybridization of basalt in different weaves leads to significant improvement in the static and dynamic mechanical properties of composites. Structure of weave, fiber type and resin properties have strong influence on mechanical properties of composites of basalt hybrid fabrics. The modulus is significantly increased in composites due to interfacial bonds between fibers and resin. Thermal behavior of fiber and composite was observed by Thermal Gravimetric Analysis and Differential Scanning Calorimetry. Thermal properties are also affected by hybridization. Thermal conductivity is strongly affected by resin properties. Fractography studies of the damaged surface are also demonstrated.
