ABSTRACT. In the current work epoxy resin is chosen as matrix, treated Sacharum offinarum (SugarCane) fiber, Pennisetum typhoides (Jowar)/ Fillet miller (Ragi) filler are chosen as reinforcement. Room temperature cured Epoxy System filled with Sacharum offinarum fiber and Pennisetum typhoides (Jowar)/ Fillet miller (Ragi) filler are synthesised by mechanical shear mixer, then kept in a Ultra sonic Sonicator for better dispersion of Pennisetum typhoides (Jowar)/ Fillet miller (Ragi) filler in the matrix. Different weights of modified Pennisetum typhoides (Jowar)/ Fillet miller (Ragi) filler (1,2,3,4,5 gm wt) has been incorporated into the Epoxy matrix in order to study the variation of Mechanical and Thermal properties.Mechanical properties like Flexural strength, Tensile strength and impact strength of the micro hybrid composite are studied by UTM (Universal Testing Machine). Thermal properties of micro hybrid composites are studied using Thermo Gravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC).
The mechanical behaviour of glass fiber reinforced polymer (GFRP) composite depends on the type of matrix, filler, and fiber architecture. In order to develop high-strength polymer matrix composites, the composites containing 5%, 10%, and 15% each of Portland grey and white cement filler are prepared by uniformly mixing the epoxy and filler materials, followed by casting by hand layup technique. The flexural and shear test is performed in accordance with ASTM 790 and ASTM D5379, respectively. It has been found that the values of shear strength, flexural strength, and modulus of elasticity vary with the increasing amount of cement component in the polymer. In addition, for a given percentage of the components of the cementitious filler, the values of the mechanical strength of the composites that contain white cement are higher than those of the composites that contain grey cement filler. Damage to composites has been found to involve fiber breakage and delamination primarily.

Now a day’s Natural Fibres Composites owing importance due to its Bio degradability, Light weight& Strength etc ., This project aims to investigate Mechanical Property evaluation of Jute fibre Eglassfiber, without chemical treatment and applied an compression load on the Jute fibre layers to be in uniform and Unidirectional. To evaluate the mechanical properties and weights of specimens are2 and 3 layeerstaken, Epoxy & Hardener constant for all specimens. The Specimens prepared by Hand layup technique and specimen cuts with Manual Hacksaw frame and applied smooth filing to avoid notches during cutting. Testing’s for Mechanical properties evaluation used are tensile, and 3-Point Flexural testing’s on computerized UTM (INSTRON 3369). Hardness and Impact tests also performed per the ASTM standards.
