As demand grows for advanced materials with multifunctional capabilities like self-healing, thermal regulation, and electromagnetic modulation, traditional manufacturing methods for fiber-reinforced polymer (FRP) composites face scalability, energy, and efficiency limitations. Fabricating vascularized composites with internal channels often involves labor-intensive, energy-intensive, and time-consuming processes, hindering widespread adoption in aerospace, infrastructure, and healthcare. This thesis addresses these challenges by leveraging frontal polymerization (FP), a self-sustaining exothermic curing method that enables rapid polymerization and vascular network formation, reducing energy consumption by nearly four orders of magnitude compared to conventional techniques.The research introduces FP Vaporization of Sacrificial Components (FP-VaSC) as a single-step method for simultaneous polymerization and vascularization of FRP composites. A thermo-chemical model optimizes the interplay between sacrificial templates and polymerization, balancing vascular network complexity and structural integrity for different fiber configurations and spacings. Additionally, FP-assisted additive manufacturing (AM) is explored, employing a multiphysics finite element model to simulate real-time ink deposition, thermal dynamics, and front propagation. This approach provides precise control of critical parameters such as printing velocity, layer-to-layer interactions, and material compatibility, significantly reducing reliance on trial-and-error methods while enabling scalable production of intricate composite structures.Experimental and numerical studies reveal how curing rates, temperature distribution, and material properties affect residual strains, deformation, and overall part quality in FP-processed composites. These insights inform practical mitigation strategies, such as preheating and closed-loop control of printing velocity, which stabilize the polymerization front and improve dimensional accuracy. By integrating these advancements, this thesis establishes FP as a transformative, energy-efficient, and scalable method for producing adaptive polymer composites, offering a comprehensive framework and technical insights for its deployment in high-performance industries such as aerospace, automotive, and healthcare.
