Carbon fiber-reinforced composites have existed for many years [1, 2]. They represent an attempt to incorporate the exceptional mechanical properties of carbon fiber into a polymer, metal, ceramic, carbon char or pitch matrix. The fibers act as the major load-bearing elements and the matrix serves to transfer load to the fiber network. Although this composite is attractive because its high performance, the carbon fiber-reinforced composite technology is limited by the complexity of the fabrication process and the expensive carbon fibers [3, 4]. Carbon foam derived from mesophase pitch precursor can be considered to be an interconnected network of graphitic ligaments or struts having the similar structure of carbon fiber, they represent a potential alternative for carbon fiber as a reinforcement in the structural composite [5]. The carbon fiber from mesophase pitch has been achieved [6], however the carbon foam appeared to be quite fragile. It is postulated that this may be caused by...
