Abstract: In this work an attempt has been made to study and develop Natural and hybrid fibre reinforced composites (HFRC). Natural fibre reinforced composites have many advantages such as light weight, low cost, environment friendly, tensile and compressive strength, high toughness, non- corrosive nature, etc. In this study an attempt has been made to study the processing of the natural fibre ‘jute’ along with glass fibre for hybrid composite. In this work composite is manufactured by hand lay-up method. The raw materials required for the manufacturing includes resin, hardener and the catalyst. The manufacturing of natural fibre composite has been done by considering five layers of natural fibre jute while epoxy resin is used as matrix. While the hybrid composite has been prepared with one extra layer of glass fibre at the top and bottom in addition with natural fiber matrix/sample. Mechanical properties such as tensile strength, fracture strength and toughness of the natural fibre reinforced composite (NFRC) and hybrid (HFRC) has been tested. By adding glass fibres along with natural fibres in the matrix, significant improvements in the mechanical properties have been observed. A study based on orientation of the fibre reinforcements has been done to get the desired properties for applications in automotive and biomedical fields. The Rule of mixture for composites has been applied after considering the correction factor associated with fibre orientation for multidirectional fibre reinforced composites. This theoretical result has been compared to the tensile properties found by testing on a 2.5 kN load Universal Testing Machine (UTM) for both Natural Fibre Reinforced Composite (NFRC) and Hybrid Fibre Reinforced Composite (HFRC). Further, Finite Element Modelling has been done for the Jute/Epoxy matrix as well as Glass/Jute/Epoxy matrix. Stress analysis has been done for a given mass fraction of fiber and matrix. This analysis was further extended for various orientations of fibres such as [0֯/90֯/0֯/45֯/0֯/90֯/0֯]t , [-45֯/45֯/-45֯/0֯/-45֯/45֯/-45֯]t and [90֯/0֯/90֯/45֯/90֯/0֯/90֯]t.
