Polymeric Reinforcement Architectures: Multi-Functionality, Advanced Mechanics, and Modelling

Traditional composite engineering relies heavily on embedding stiff but brittle glass or carbon fibers into thermoset or thermoplastic matrices, an approach prone to interfacial delamination and high recyclability costs. To overcome these limits, polymer composite science has introduced the unique visco-elasticity and high strain-to-failure capacity of organic polymeric reinforcements—ranging from oriented tapes to multi-material textile lattices. This advancement bridges the crack-bridging micromechanics-based practices with modern tailored multi-functional polymeric reinforcements which enhances the overall sustainability and performance quotient of resulting materials. The possible applications of polymeric reinforcements include, but not limited to, (i) the development of fully recyclable, single-chemistry self-reinforced composites (SRCs), or (ii) introduce ductile, energy-dissipating fiber networks that arrest fractures in brittle concrete, geopolymers, and advanced thermosets. Robotic additive manufacturing (3D-printing) and voxel-scale topology optimization allow engineers to deposit these polymeric phases with unprecedented spatial accuracy. This Research Topic unites these processing trajectories to explore the importance of polymeric reinforcements and programmed macromolecular architectures towards improving the macro-scale structural performance.The rapid growth of digitally fabricated composites is currently held back by isolated research silos. Structural engineers frequently evaluate macro-polymer fibers in concrete without examining microscopic interfacial shear stress or fiber-matrix bond evolution. Concurrently, polymer chemists synthesize sustainable single-polymer formulations without clear paths to industrial manufacturing, while computational designers map out complex metamaterial topologies that ignore the anisotropic flow defects and extrusion mechanics inherent to raw polymer processing. This fragmentation hides underlying physical connections and slows down real-world engineering breakthroughs.This Research Topic provides a shared forum to treat polymeric reinforcement as a dynamic, mechanistically understood element. By combining advanced mathematical topology, extrusion rheology, and destructive micromechanical testing, we intend to bridge the gap between computer-aided designs and predictable structural components. We invite papers that solve the thermal, chemical, and physical mismatches found in hybrid polymer systems. Our ultimate objective is to establish the fundamental design rules that will guide the next generation of resilient, intelligent, and circular architected materials.We invite manuscripts grounded in rigorous experimental, simulations or analytical methods. Submissions must explicitly focus on polymeric reinforcement phase, exploring both theoretical behavior and scalable manufacturing across diverse fields. Cross-disciplinary work bridging scales—from interface performance to system-level response—is highly encouraged. Core submission themes include (but not limited to): • Theme I (Toughening): Pullout mechanics, Micro-crack bridging, and Bond durability of polymer textiles and 3D-printed polymeric reinforcement in Cementitious, Geopolymer, Ceramic or Thermoset matrices. • Theme II (Multifunctionality): 4D printing, Embedded piezoresistive health monitoring, Self-healing networks, and Stimuli-responsive shape-memory lattices.• Theme III (Single-Polymer Systems): Recyclability, 3D-printing, Sustainability + Performance metrics of chemistry-matched self-reinforced polymeric composites, Processing windows development and characterization, Hot compaction.• Theme IV (Digital Metamaterials): Single/Multi-polymer co-extrusion, Voxel-scale optimization, Toolpath design, and Interdiffusion bond kinetics.
