Reinforcement Learning–Based Temperature Control for Automated Tape Laying of Thermoplastic Prepregs

Author: [Bruce Zhou]Affiliation: [Jota Machinery Composites Material Prepreg Solution]Corresponding Author: [jotamachinery@gmail.com]Published : November 28 , 2025 Abstract Automated tape laying (ATL) of thermoplastic unidirectional (UD) tapes is highly sensitive to temperature fluctuations at the nip point, where tape, substrate and consolidation roller meet. Classical open-loop heater settings and model-based controllers often struggle to compensate for

Design and Analysis of 3D-Printed Continuous Carbon Fiber Reinforced Thermosetting Composites

Author: [Bruce Zhou]Affiliation: [Jota Machinery Composites Material Prepreg Solution]Corresponding Author: [jotamachinery@gmail.com] Abstract Additive manufacturing of continuous fiber–reinforced polymer composites remains constrained by matrix selection and deposition physics. Conventional continuous fiber printing requires matrices that solidify immediately after extrusion, restricting the material palette to thermoplastics or ultra-fast-curing thermosets. This limitation excludes most aerospace-grade epoxy systems whose
