摘要整理
连续碳纤维（CCF）因其高强度、高模量、轻质和化学稳定性等优势在众多关键应用领域具有重要前景。然而，在大多数研究和应用中，CCF主要用作承载结构部件，其优异的导电性能尚未得到充分开发。为进一步挖掘CCF的导电优势并拓展其应用潜力，本研究采用混合3D打印技术制备了一系列具有三重周期极小曲面（TPMS）孔隙结构的CCF磁电功能复合材料。基于TPMS孔隙结构设计策略，该工作展示了CCF功能复合材料的动态冲击能量吸收性能，吸收效率超过49%。通过建立动态载荷与输出电信号的关联关系，实现了动态载荷传感，与载荷的线性相关性良好，R²值高达0.99。该设计理念进一步应用于船体制造，用于吸收波浪能量并将其转换为电信号。打印的船体能够感知水波，峰值传感电流达10 µA。本研究提出的方法和见解为CCF应用领域的拓展提供了重要参考价值。
