目的是开发一种监控方法，以控制在役玻璃/树脂材料的损坏，从而实现预防性维护。在制造过程中，碳纤维电阻传感器直接引入复合材料内部。在复合材料结构加载过程中，碳纤维的伸长和断裂导致电阻的增加，并对其进行监测。最后对传感器的电气响应进行建模，以开发实时损伤监测系统。统计函数（Weibull，Sigmoid）用于描述碳纤维的连续失效现象。该概念在承受双轴载荷的复合管上得到了验证。

The aim is to develop a monitoring method for controlling the damage of glass/resin materials in-service for a purpose of preventive maintenance. Carbon fiber resistive sensors are introduced directly inside composite materials during manufacturing. The increase of their electric resistance, caused by elongation and then rupture of carbon filaments during loading of the composite structure, is monitored. Finally the sensors electric response is modeled in order to develop a real time damage monitoring system. Statistic functions (Weibull, Sigmoid) are implemented to describe successive failure phenomenon of carbon filaments. The concept is validated on composite pipes subjected to biaxial loading.
