Filled composites are processed by adding the filer materials to plastic matrices which enhances the strength and reduces the weight of the composites. The filler particles can be irregular or polyhedrons, short fibers or spheres in shape and they acts as the primary or additional ingredient in a composite. The base matrix possesses networks of open pores resembling to that of a group of cells or honeycomb structures. The infiltrate binds the components like powders or fibers in the matrix [13]. The matrix is not naturally formed in the honeycomb structure, but is specifically processed to fit to a predetermined shape. They are seldom used to impart color or opacity to the composite in which they are utilized. In their role as inert additives, they can change matrix characteristic in all directions. The properties of the final composite are greatly dependent on the blend of particle types, surface treatment, shape and size of the particle in the filler material. The advantages of fillers included increase stability, stiffness, porosity, strength, thermal resistance, coefficient of thermal expansion and abrasion resistance [21].
