Synergistic Strength-Toughness Gradient Design in Co-Extruded WPC/CFMP Composites
Wood-plastic composites (WPCs) have gained recognition in the architectural and construction industries due to their sustainability, ease of processing, and aesthetic flexibility. However, their limited load-bearing capacity and inherent brittleness restrict their use in demanding structural applications. The integration of carbon fabric mesh prepregs (CFMPs) through co-extrusion offers a new pathway to overcome these challenges. By combining material science and architectural engineering principles, this study explores the development of a high-performance composite system (BPC-CFMP) with superior mechanical adaptability for architectural components. Problem Identification and Research Gap Conventional WPCs exhibit inferior toughness and low fracture resistance, leading to early failure under high-stress conditions. Although fiber fabric prepregs provide bidirectional reinforcement, their post-curing rigidity often limits flexibility, resulting in brittle fractures under load...
