The effect of dispersion, alkali treatment, resistance to chemicals and influence of silica powder on mechanical, thermal properties of hybrid fibre (i.e. jute/glass) composites were investigated as a function of silica loading. NaOH treatment of jute fibres was found to increase the interface between matrix and hybrid fibres. Thus, tensile strength was improved significantly up to 6 wt % silica content, decreases further increase in silica content beyond 6 wt %. Tensile modulus of hybrid composites was tremendously improved up to 15 wt. % silica content. Author proved hybrid composites are resistant to attack of all chemicals except Toluene. (DSC)&(TGA) were improved significantly the glass transition temperature and thermal stability of the treated hybrid fiber at various silica loadings.
