Enhancement of FDM ULTEM® 9085 bond strength via atmospheric plasma treatment
Autor: Tait D. McLouth, Rafael J. Zaldivar, Hyun I. Kim, Sara M. Gustafson
Publikováno v: Journal of Manufacturing Processes. 66:179-188
The present study investigates a process to improve the bond strength of ULTEM® 9085 manufactured via fused deposition modeling and presents an application of this technique as a repair method for damaged 3D-printed structures. The initial surface c

Elevated Temperature Notch Sensitivity of Inconel 718 Manufactured by Selective Laser Melting
Autor: Julian R. Lohser, Scott D. Sitzman, Glenn E. Bean, David B. Witkin, Tait D. McLouth, Rafael J. Zaldivar, Paul M. Adams, Jenn-Ming Yang
Publikováno v: Journal of Materials Engineering and Performance. 30:4882-4890
Notched alloy 718 tensile specimens prepared by selective laser melting (SLM) and wrought bar were tested at 550, 650, and 750 °C. SLM specimens were tested with either an as-printed or a machined notch. For both types there was a decrease in streng

Investigations on the effect of plasma treatment on the adhesive bonding behavior of ultra high modulus K13C2U/cyanate ester fiber composites
Autor: Hyun I. Kim, Daniela Marques, Catherine Barrie, Rafael J. Zaldivar
Publikováno v: Journal of Adhesion Science and Technology. 35:1263-1283
Surface preparation of ultra-high modulus fiber composites for adhesive bonding is challenging due to the subsurface damages that can occur during a standard abrasion operation that could weaken th...

The effect of radiation exposure on carbon fiber-reinforced Rohacell® core laminate structural composites
Autor: Rafael J. Zaldivar, C Barrie, Dhruv N. Patel, D Marques
Publikováno v: Journal of Composite Materials. 54:2261-2269
Two equivalent density foams with identical shear strengths were used to manufacture carbon-fiber reinforced composite sandwich structures. One foam core system (Rohacell® 71 WF) has a cell diameter of 1117 µm and a wall thickness of 29 µm, while

Publikováno v: Hard X-Ray, Gamma-Ray, and Neutron Detector Physics XXIII.
Scintillation materials for the spectroscopic detection of gamma photons have been made of inorganic crystals, organic liquid and plastic scintillators. These scintillators are either expensive for large-area detection or incapable of gamma spectrosc
