Abstract Influence of nanoclay dispersion on mechanical, dynamic mechanical and free vibration characteristics of basket type intra-ply woven banana/jute (banana yarn-weft direction, jute yarn-warp direction) hybrid polyester composite has been investigated. Results revealed that loading of nanoclay enhances the mechanical properties of the composite significantly as it improves the adhesion between fiber and matrix. Dynamic mechanical analysis result reveals that nanoclay addition significantly increases the storage modulus and glass transition temperature of the intra-ply hybrid composite. From free vibration studies, carried out on laminated beam like structures, it is found that the natural frequency of the composite laminate increases till 2 wt% of nanoclay while the modal damping increases when the wt% of nanoclay is more than 2. However, due to the agglomeration effect of nanoclay the properties are not improved for nanoclay loading beyond 2 wt%. Keywords Nanoclay properties

1 Introduction Natural fibers can be used an alternative material to conventional synthetic fibers such as glass, carbon, boron and kevlar fibers. Natural fibers such as banana, jute, sisal and hemp have advantages such as low cost, less weight, easy to process and bio-degradable compared to the synthetic fibers (Joshi et al. 2004; Venkateshwaran et al. 2011). Several researchers have investigated mechanical properties of several natural fiber hybrid composites and demonstrated that hybrid composites have better mechanical strength. Jacob et al. (2004) investigated the effect of sisal/oil palm fiber in natural rubber composite on mechanical properties. They concluded that increasing the concentration of fiber in matrix reduces the tensile strength. Venkateshwaran et al. (2011) analyzed the banana/sisal/epoxy hybrid composite with different fiber length and weight percentage. They achieved better mechanical properties for 50 wt% of sisal fiber in banana/epoxy composite. Jawaid et al. (2011) hybridized the oil palm empty fruit bunch fiber mat with woven jute composite and found that hybridized composite got maximum tensile and flexural result. Several researchers demonstrated that based nanoclay added composites increases mechanical and dynamic properties such as tensile strength, modulus and glass transition temperature of composites compared to same
