In this modern era, the natural fibers usage in automobile and construction sectors has been increased. The goal of the current work was to investigate the fiber orientation effect on dynamic mechanical properties of hybrid Pineapple Leaf Fibre (PALF) hybridized with basalt reinforced epoxy composite at changing vibration frequencies. Hand Lay-up technique was used to manufacture the composites by keeping the unidirectional basalt fabric as an outer layer by keeping PALF as inner layer followed by static compression method. Tensile and flexural moduli were also determined apart from storage modulus ( E ′) and damping factor (tan δ ) for different PALF fiber angles. The results exemplified that not only the storage modulus and loss factor but also glass transition temperature ( Tg ) as well found to increase with frequency and also the fiber orientation angle has a greater impact on dynamic and static properties.
