Abstract The fabrication of carbon fibre-reinforced polymer (CFRP)-based shape memory alloy hybrid composite (SMAHC) beams is highly challenging because conductive carbon fibres alter the electrical characteristics of the beams when driven by an electrical current. Here, we propose and fabricate a CFRP-based SMAHC beam with embedded SMA actuators using the electrical insulation methods. We firstly implemented a self-sensing-based deflection control of the CFRP-based SMAHC beam for unit-step and sinusoidal wave targets using its resistance as a feedback signal for estimating self-sensed deflection. The results reveal that the deflection was well controlled; however, the responses were slightly delayed. Therefore, in our future studies, we will concentrate on overcoming this response delay. Nevertheless, we found that the proposed SMAHC beam is highly feasible and can form the basis for future self-sensing-based controllable CFRP composite morphing structures.

基于碳纤维增强聚合物（CFRP）的形状记忆合金混合复合梁的自感知挠度控制

摘要 碳纤维增强聚合物 (CFRP) 基形状记忆合金混合复合材料 (SMAHC) 梁的制造极具挑战性，因为导电碳纤维在电流驱动时会改变梁的电气特性。在这里，我们提出并使用电绝缘方法制造了带有嵌入式 SMA 致动器的基于 CFRP 的 SMAHC 梁。我们首先实现了基于 CFRP 的 SMAHC 光束的基于自感应的偏转控制，用于单位步长和正弦波目标，使用其电阻作为反馈信号来估计自感应偏转。结果表明，挠度得到了很好的控制；然而，答复稍有延迟。因此，在我们未来的研究中，我们将专注于克服这种响应延迟。尽管如此，
