TA表面改性UHMWPE织物/聚氨酯层压板的制备及其力学性能研究
Study on preparation and mechanical properties of TA-modified ultra-high molecular weight polyethylene fabric and polyurethane laminates
摘要
Abstract
To enhance the interfacial properties and overall mechanical performance of ultra-high molecular weight polyethylene(UHMWPE)fabric/polyurethane laminates,tannic acid(TA)and TA-ZnO surface modifica-tion techniques are employed to strengthen the interfacial bonding between fibers and the resin matrix.The influ-ence of the modification process on the mechanical behavior of the composites is systematically investigated.Three types of laminates are prepared through hot-press molding:unmodified UHMWPE/WPU,TA-modified UHMWPE@TA/WPU,and TA-ZnO-modified UHMWPE@TA-ZnO/WPU.The results reveal that TA-ZnO modification significantly improves the interfacial bonding strength of the laminates.Specifically,the interlayer peel strength of UHMWPE@TA-ZnO/WPU is increased by 48.57%to reach 0.52 N/mm,and the interlayer shear strength is enhanced by 51.11%to 0.68 MPa.Dynamic mechanical analysis(DMA)indicates that both the storage modulus and loss modulus of the modified materials increase simultaneously,demonstrating enhanced energy storage and dissipation capabilities under dynamic loads.The study demonstrates that by increasing fiber roughness and introducing hydroxyl polar groups,the chemical bonding and mechanical interlocking between fi-bers and resin are effectively strengthened,providing an effective technical approach to addressing interfacial delamination issues in composites.关键词
