Abstract: Carbon/phenolic composites have been ubiquitous in applications involving thermal ablation and high-pressure applications for aerospace structures; however, investigations are ongoing to produce parts with low porosity and high mechanical properties to reach the desired application. The study focused on investigating porosity and evaluating the integrity of carbon/phenolic composites manufactured through low-pressure and high-pressure injection processes, invariably focusing on achieving superior material properties, specifically low-porosity, and improved mechanical strength to meet desired applications. A modified high-pressure injection process has been developed to study the effect of increased pressure on part quality and porosity in juxtaposition to low-pressure injection. Non-destructive and destructive methods were employed to evaluate part quality and mechanical integrity. The outcomes revealed a noteworthy reduction in percent porosity through the utilization of the developed high-pressure injection process. Concurrently, there was a discernible enhancement in mechanical properties of the modified high-pressure injection process compared to parts manufactured using the low-pressure injection process. The significance of this study lies in its contribution to the ongoing efforts in material advancements by minimizing porosity in carbon/phenolic composites. The research aids in optimizing manufacturing processes, offering insights that pave the way for improved material performance in critical applications that require improved thermal ablation and corresponding strength.
