材料的智能化是指能够有效地利用感知功能获取损伤信息而在最佳条件下迅速将其修复再生的功能 ,理想的智能化材料必须是将传感器功能、信息处理机功能、促动器功能综合成一体的材料。当前实用化的传感器材料有光纤、ＴｉＮｉ形状记忆合金、压电陶瓷和应变片 ,就他们的应变敏感 The intelligent material refers to the function that can effectively use the sensing function to obtain the damage information and quickly repair and regenerate it under the best conditions. The ideal intelligent material must integrate the sensor function, the information processor function and the actuator function Into one material. The current practical sensor materials are optical fibers, TiNi shape memory alloys, piezoelectric ceramics and strain gauges that are sensitive to their strain
