  This project is focused on investigating the structural performance of parts
and structures produced using the latest additive manufacturing techniques. For
additive manufacturing of test coupons, fused deposition modeling of
fiber-reinforced polymer (RFP) and high-resolution low-force stereolithography
(LFS) thermoset resin printing systems were employed. UV thermoset resin was
used for LFS printing, while RFP printing adopted two different types of
filaments: amorphous polycarbonate carbon fiber filaments and semi-crystalline
Nylon 12 glass fiber filaments. For the experimental work, specimens were
printed for tension, compression, and shear tests. Additionally, mode-II
interlminar fracture in these specimens was explored. The elastic modulus and
strength values of these specimens were compared with the data of oven-cured
T700G/2510 composites. The experimental work herein will be extended to develop
damage models for 3D-printed structural parts and structures for aerospace and
space applications.
