This paper mainly focuses on the Nano clay effect in mechanical properties of sisal/banana hybrid FRP composites. The composites with and without the addition of Nano clay have been made by fusing sisal/banana fiber up to maximum volume of 30% as support in polymer matrix and mechanical properties are Investigated. The composite material prepared was tested for tensile, flexural, impact strength with aid of respective apparatus. Fiber length and % of weight were calculated initially for preparation of specimens. Banana fiber was hybridized with sisal fiber to examine the changes in mechanical properties of the samples. Mechanical properties (Tensile strength, Flexural strength along with their modulus) of the composites with nano clay   are found to be 0.8, 1, 1.5 and 2.3 times greater than that of composites without nano clay. 50% better results in the impact test were achieved. SEM analysis was carried out on the samples after conducting the test to find out the fracture pattern and the fiber pull out.  The experimental outcomes illustrate that under testing the mechanical properties shows an increase with adding up of Nano clay at higher volume fraction. Tensile & flexural properties show an affirmative hybrid effect.
