Edwin Romero has completed his Ph.D. under the advisement of Professor Rodney Trice (MSE) and Professor Eduardo Barocio (ME)! His research focused on developing carbon/carbon (C/C) composites with extrusion deposition additive manufacturing technology. The post-pyrolysis char yields and dimensional stabilities of several composite materials were compared to identify the best material for developing complex near-net-shaped C/C composites. Densification via polymer infiltration and pyrolysis, as well as X-ray micro-computed tomography scans and mechanical tests were also performed to gain better insight into the viability of 3D printed C/C composite hot structures and thermal protection systems. Dr. Romero is already working as an R&D scientist/engineer at Honeywell.
