Polymer nanocomposites are defined as the combination of a polymer matrix and nano-sized additives. Fibrous polymer composites are gradually and steadily replacing the conventional metallic materials in almost all sectors of applications. However, environmental sensitivity and its implications on properties and performance of this class of material are the serious concern of the material scientists and technologists. This chapter emphasizes on the addition of nano-TiO2 filler into the epoxy matrix on water absorption, thermal and mechanical properties of glass fiber reinforced polymer (GFRP) composites. The effect of nanofillers content on water absorption and thermal and mechanical properties is evaluated and compared with neat epoxy glass fiber reinforced polymer (GFRP) composites. Weibull design parameters are determined to confirm the nominal flexural strength and its randomness of the experimental results. Fractography analysis supports the enhancement or deterioration of water diffusion coefficient and mechanical and thermal properties through field emission scanning electron microscopy.
