| Abstract Scope |
Interest in thermoplastic composites in aerospace, marine, and renewable energy industries is growing due to their advantageous qualities such as higher toughness, shorter processing times, potential for recyclability, and easier repair as compared to thermosetting composites. In processing of thermoplastic composites, vacuum bagging-only (VBO) in an oven emerges as a cost-effective and efficient means of consolidation without the need for autoclaves or heated presses. This method simplifies the process by placing the laid-up layers into a vacuum-sealed bag, creating a uniform pressure on the layers, and raising the temperature to allow the laminates to bond. It has been demonstrated that this process significantly boosts interlaminar properties of resulting coupons. The aim of this study is to investigate the effects of processing on interlaminar bonding, void content, and void morphology in parts manufactured via vacuum bag only (VBO) process. Test samples will be fabricated using carbon fiber reinforced low-melt polyaryletherketone (LM-PAEK) through hand-layup and will be consolidated in a vacuum bag within an oven. Short beam shear (SBS) and transverse tensile tests will be conducted and correlated to processing conditions and void content/morphologies. The findings are expected to optimize VBO processing for improved thermoplastic composite performance. |
