Abstract
This study introduces an innovative Modified Mantell and Springer (MMS) model to more accurately assess degree of intimate contact with improved accuracy for laser-assisted fiber placement (LAFP), which also significantly enhances the subsequent degree of healing estimation and enables the presentation of an improved degree of bonding. Process parameters such as placement speed and consolidation forces, and fiber orientation are identified as key determinants of bonding quality. Lower placement speeds and higher consolidation forces are linked to increased healing and intimate contact between layers, crucial for achieving desired degree of bonding. The MMS model proves effective in capturing the influence of fiber orientation, revealing that [0°/0°] orientation exhibits superior bonding strength. Validation through T-peel tests provides tangible evidence of the model's precision, aligning fracture surface observations with model predictions. This research contributes to a comprehensive understanding and prediction of composite bonding quality, offering valuable insights for optimizing manufacturing processes and enhancing the mechanical performance of composites manufactured with LAFP.
