Additive manufacturing (AM) offers key benefits to manufacturing: freedom of design, reduced material waste, and rapid prototyping, to name a few. However, few AM methods have been investigated for the creation of Carbon/Carbon (C/C) composites, which are well known for having excellent high temperature properties. A direct ink writing (DIW) method, one of many established AM processes, is presented for creating C/C composite structures from liquid phenolic resin inks. A low molecular weight gelator, which self-assembles in solution, was used to modify the ink rheology and carbon fiber content was varied for its impact on the mechanical properties. This work examined the properties of the inks leading to the best prints as well as the properties of the cured composite (carbon-conversion, carbon fiber orientation, and mechanical performance).
