Due to superior material properties of fiber reinforced composites, they are utilized in many structural fabrications. Even though many studies have been reported about various fiber reinforced composites, it is indeed to find more eco-friendly composites for modern applications. So, developing the new fiber reinforced composites and revealing its mechanical properties are vital. In this examination, the natural fiber reinforced polymer matrix composite was prepared by compression molding method. The natural fiber named as Coccinia Indica was used to fabricate the fiber reinforced composites. The impact of different fiber length on dynamic mechanical properties like loss modulus, storage modulus, and loss of weight in fiber reinforced composites was predicted using dynamic mechanical analysis and thermogravimetric analysis. The outcomes revealed that fiber length of 30 mm shows better values in storage modulus and nominal loss modulus owing to higher interfacial bonding among fiber and matrix. However, in other fiber lengths, the storage modulus depicts poor result and high loss modulus is due to inefficient stress transfer.
