| Abstract Scope |
Polyamide-12 (PA-12) reinforced with glass microfibers (GMF) is gaining interest due to its high strength, lightweight, and compatibility with powder bed fusion (PBF) additive manufacturing (AM) technology. The AM processed GMF/PA-12 composite parts are typically subjected to different environmental conditions during their field applications that might affect their mechanical properties. This study focuses, specifically on temperature and humidity effects on stress-strain and failure behavior. First the ASTM D638 Type 4 standard tensile samples are fabricated using the Formlabs Fuse 1 printer. Several samples are exposed to different temperature and humidity conditions. The stressed and pristine samples are subjected to tensile tests to extract mechanical properties of the materials. In addition, microscopy of the failed surfaces is done to understand the effect of environmental exposure on failure mechanisms. Preliminary observations suggest that these environmental conditions lower stiffness, weaken the material, and cause earlier failure. |
