“…For a composite material, it is essential to have the highest possible wetting of the reinforcement by the matrix to achieve superior mechanical and physical response. 19 From various SEM images, the interaction of the matrix and reinforcement appears to be well complimented, fiber, and matrix both being carbon materials offer the highest compatibility, and the same is well witnessed in the micrographs. Furthermore, Figure 8(a) and (c) reviles a peculiar behavior; pores present in the foam are well crossed with the randomly oriented fiber; this significantly adds on the extra surfaces, which increases the net surface area.…”

Novel carbon foam composites derived from various pitch precursors have been fabricated and characterized. This paper specifically focuses on developing an effective process for fabricating the carbon foam composites from Polyacrylonitrile (PAN)-based carbon felt as a reinforcement and various readily available pitch matrix such as petroleum pitch, coal tar pitch, and mesophase pitch. The paper endeavors to develop the carbon foam composites and to carry out detailed morphological, thermal, and mechanical characterization. Traditional carbon foams have been known to offer poor mechanical performance, and hence, in this paper, the pitch-based carbon foams were innovatively reinforced with the PAN-based carbon fiber felt. Carbon foam composites were subjected to partial oxidation, and their morphological and mechanical response after the heat treatment was studied thoroughly. Thermal gravimetric analysis and thermal mechanical analysis techniques reveal an appreciable thermo-physical and thermo-mechanical response at elevated temperatures. Also, it was found out that the factors such as volatile content and quinoline insoluble fraction affect the morphology as well as the physical robustness on the composite foams.

“…Over the last decade, carbon-carbon (C/C) composites have emerged as a favorite material for high-temperature engineering applications because of the reduction in the price of the carbon fiber and discovery of new potential material for matrix. [1][2][3][4] C/C composites have shown the brightest behavior in various engineering applications where micro-wear and low friction coefficient, along with high-temperature stability, a superior mechanical response is desired. Because of the phase similarity in the C/C composites, i.e.…”

Carbon–carbon composites, as developed from various pitch precursors and chopped carbon fiber reinforcement, have been characterized and compared on the prime basis of the precursor materials used as the matrix. Evaluation of the properties and characterization have been carried out by various techniques such as thermal analysis by thermogravimetric analysis, thermomechanical analysis, and flame ablation method, microstructural characterization by scanning electron microscopy and optical microscope, mechanical characterization by Universal Testing Machine (UTM), IZOD impact, and hardness and frictional characterization by a pin on disc tribometer were carried out. Petroleum pitch, coal tar pitch, and the mixture of both the kinds of the pitch have shown a difference in the ultimate properties on the finished composite materials. The presence of volatiles, quinoline insoluble content, and various softening point have proved to impart differences in behavior for different systems. Composites developed to form the three systems have shown robust characteristics with superior mechanical and thermal behavior. Microstructural analysis has shown good compatibility between the reinforcement and matrix, while it is also evidence of a uniform distribution of the reinforcement. The fiber–matrix interaction in all the three systems is appreciably weak, which is favorable for non-catastrophic failure.
