Abstract Scope |
Continuous fiber composites provide added toughness to otherwise brittle materials but are difficult to manufacture. Additive manufacturing (AM) allows formation of intricate shapes that would otherwise require complex processing procedures. Continuous Fiber 3D Printing (CF3D®) has been developed to yield complex-shaped Polymer Matrix Composite (PMC) components at elevated speeds and reduced costs compared to traditional manufacturing. PMCs produced by CF3D® will be pyrolyzed to form a preform that will be densified using a polymer infiltration and pyrolysis (PIP) technique, forming a ceramic matrix composite (CMC). Initial pyrolyzation was performed at various temperatures and heating rates and the resulting carbon fiber preform was characterized to determine porosity and residual char. A carbon-yielding polymeric resin was chosen to densify the preform through vacuum infiltrations. This poster will present the thermal characterization of the PMCs as well as preliminary microstructural characterization of the composites after thermal treatment and densification. |
