Abstract Scope |
Composite-Based Additive Manufacturing (CBAM) is a new high speed sheet lamination AM process in which thermoplastic or thermoset matrix powder is selectively deposited onto non-woven carbon fiber sheets. The individual sheets are stacked and placed in a heated platen press which thermally fuses the powder particles in/around the fibers. Sand blasting is used to remove unbound fibers around the part. As this is a new composite AM process, there are essentially no published studies in the literature. For this study, non-woven carbon fiber sheets were used with either PA-12 or PEEK as the polymer matrix. Coupons fabricated at numerous build orientations were tested in tension and flexure to determine orientation-specific properties. X-ray CT scans were used to assess porosity of fabricated parts in relation to powder loading and thermal processing conditions. Micrographs of fracture surfaces were studied to gain insight into failure behavior of the material. |
