Two major components of a composite are high-strength ﬁbers and a matrix that binds these ﬁbers to form a composite-structural component. The ﬁbers provide strength and stiffness, and the matrix (resin) provides the transfer of stresses and strains between the ﬁbers. To obtain full composite action, the ﬁber surfaces should be completely coated (wetted) with matrix. Two or more ﬁber types can be combined to obtain speciﬁc composite property that is not possible to obtain using a single ﬁber type. For example, the modulus, strength, and fatigue performance of glass-reinforced polymers (GRP) can be enhanced by adding carbon ﬁbers. Similarly, the impact energy of carbonﬁber reinforced polymers (CFRP) can be increased by the addition of glass or aramid ﬁbers. The optimized performance that hybrid composite materials offer has led to their widespread growth throughout the world (Hancox, 1981; Shan and Liao, 2002). In recent years, hybrid composites have found uses in a number of applications such as abrasive resistant coatings, contact lens, sensors, optically active ﬁlms, membranes, and absorbents (Cornelius and Marand, 2002).
