Jute fibre reinforced epoxy based composites were manufactured by vacuum bagging method using three different jute fibre structures; woven fabric, non-woven mat and carded sliver. The composites were made using different number of layers of reinforcing materials. Then the tensile test on composite laminates was conducted in different directions of composites according to ASTM D 3039 standards. The tensile properties were evaluated as a function of fibre architecture (woven, non-woven and sliver), fibre volume fraction and direction of applied load.The tensile modulus of woven fabric reinforced composites was found 100% higher (maximum), carded sliver reinforced composites was found 110% higher and non-woven mat reinforced composites was found 53% higher (maximum) than the tensile modulus of pure epoxy resin. There were not any significant influences found in tensile strength for jute fibre reinforcement.The strengths and modulus of composite laminates also depend on fibre content and tensile properties of reinforcing materials. For woven fabric reinforced composites, maximum strength and modulus observed when tested along weft direction. For non-woven mat reinforced composites, maximum strength was found along Machine direction (MD). In case of woven fabric and non-woven mat reinforced composites, strength and modulus was increased with increase of fibre volume fraction.For 20% normalized fibre volume fraction, tensile strength and modulus was found maximum for woven fabric reinforced composites tested along weft direction and minimum for non-woven mat reinforced composites; tensile strength and modulus for carded sliver reinforced composites was in between these two.This relation between fibre architecture and tensile properties of composites is critically analyzed and reported in this research.
