Optical characterization of fiber-reinforced thermoplastic tapes for laser-based composite manufacturing
Measured reflection and absorption of UD thermoplastic tapes, which form the basis of OTOM’s BRDF reflection model.
A fully coupled local and global optical-thermal model for continuous adjacent laser-assisted tape winding process of type-IV pressure vessels
Couples the local nip-point model with the global thermal history of the vessel, so heat from adjacent windings is captured.
New process optimization framework for laser assisted tape winding of composite pressure vessels: Controlling the unsteady bonding temperature
Holds the bonding temperature within 1.5 °C across cylinder and dome. See the vessel case study.
Temperature variation during continuous laser-assisted adjacent hoop winding of type-IV pressure vessels: An experimental analysis
Measured temperature variation during continuous hoop winding, used as reference data for the models.
3D numerical modeling of laser assisted tape winding process of composite pressure vessels and pipes: effect of winding angle, mandrel curvature and tape width
A 3D model of how winding angle, curvature and tape width change the heat input and the temperature.
Conference papers
Numerical modeling of laser assisted tape winding process
Non-specular (BRDF) reflection and different laser intensity distributions were studied, and the developments were integrated into OTOM.
Non-hoop winding effect on bonding temperature of laser assisted tape winding process
A model of laser rays and their reflections on the nip-point temperature for non-hoop (arbitrary-angle) winding, developed in OTOM.
In-line physics-based model simulation for process modeling of laser tape winding
A fast temperature prediction algorithm for model-based control and in-line monitoring, which became the base flowchart of OTOM.
Experimental and numerical analysis of laser reflection for optical-thermal process modeling of tape winding
How surface texture changes reflectance during the process, which extended the BRDF towards anisotropic, temperature- and texture-dependent reflection in OTOM.
