基于碳纳米传感器的复合材料双螺栓连接结构损伤监测研究
Research on Structural Damage Monitoring of Double-bolted Composite Joints Based on Carbon Nanosensors
摘要
Abstract
With the continuous development of aviation technology,composite structures have been widely used in various complex working environments and load-bearing parts.However,composite materials are prone to initial damage during bolt connections,such as matrix cracking,fiber fracture,and delamination,leading to a decrease in structural load-bearing efficiency and an increased risk of failure.Therefore,real-time monitoring of damage to bolted connection structures during service has become particularly important.Traditional non-destructive testing methods are limited by the environment and equipment,making it difficult to monitor structural damage in real-time.This paper studies the damage process of double bolt connection structures based on carbon nanosensors.Through temperature monitoring experiments,fatigue monitoring experiments,and strain monitoring experiments of double bolt structures,the response law of the resistance change rate of carbon nanosensors under temperature changes and fatigue loads is analyzed.The research results indicate that the sensor has good effectiveness in temperature and damage measurement,providing new research ideas and methods for health monitoring of composite material structures.关键词
