A natural embodiment for multifunctional materials combining energy-storing capabilities and structural mechanical properties are layered structures, similar to both laminate structural composites and electrochemical energy-storage devices. A structural composite with integrated electric double layer capacitive storage is produced by resin infusion of a lay up including woven glass fabric used as mechanical reinforcement, carbon nanotube non-woven fabrics as electrodes/current collectors and a polymer electrolyte. The energy-storing layer is patterned with holes, which after integration form resin plugs for mechanical interconnection between layers, similar to rivets. Finite element modelling is used to optimise rivet shape and areal density on interlaminar shear properties. Galvanostatic charge-discharge tests during three-point bending show no degradation of properties after large deflections or repeated load/unload cycling at 3.5 V. This mechanical tolerance is a consequence ...

通过整合碳纳米管纤维，可实现耐损伤的层压结构超级电容器复合材料

结合了储能能力和结构机械性能的多功能材料的自然实施例是分层结构，类似于层压结构复合材料和电化学储能装置。通过树脂灌注的叠层来生产具有集成双电层电容存储的结构复合材料，该叠层包括用作机械增强的玻璃纤维织物，用作电极/集电器的碳纳米管无纺布以及聚合物电解质。储能层上带有孔的图案，在集成后形成类似于孔铆钉的树脂塞，用于各层之间的机械互连。有限元建模用于优化层间剪切性能上的铆钉形状和面密度。
