Abstract Scope |
Ceramic matrix composites (CMCs) exhibit desirable thermal properties tailored for high-temperature environments, rendering them useful for applications in aircraft engines and hypersonic re-entry vehicles. However, CMCs pose a challenge to manufacture since their material properties and microstructure evolution, such as crack formation, are highly dependent on processing conditions. The paper examines processing techniques for three different material sets of CMCs with a liquid polycarbosilane precursor to silicon carbide (SiC) matrix and carbon fiber reinforcements – mini-composites, unidirectional composite laminate plates and plain weave composites. The microstructures of the composites are characterized using x-ray computed tomography (XCT) and scanning electron microscopy (SEM) imaging at four different temperatures within the first stage of the Polymer Infiltration and Pyrolysis (PIP) cycle. Newfound data on crack initiation, growth and size as a function of processing temperature can be used to create a process model that will replicate the manufacturing process of CMCs, which will lead to the apprehension of optimal processing parameters for these materials. |
