The problems of conventional materials direct the development of newer materials like polymer matrix composite materials. Natural fibre made polymer matrix composite materials have gained importance in the recent years. Investigations are carried out in this work to make use of natural fibre as they are strong, light weight and cheap. Natural fibres like gongura are abundantly available in South India. In this investigation, the development and characterisation of natural fibre made polymer composites, with gongura as reinforcement and hybrid polymer as matrix, are studied. The gongura fibre, after treated with alkali sodium hydroxide (NaOH) solution, is used to make composites. The influence of different parameters on tensile strength of composite is studied using ANOVA technique and the regression equation is arrived which explains the level of influence of different parameters on ultimate tensile strength of composites.
