【摘要】 为了对光纤进行金属嵌入式封装,对T2紫铜与1100(L4)纯铝进行了超声波焊接试验,在焊接过程中进行了光纤传感器的嵌入试验.嵌入的光纤传感器分别选用裸光纤、化学镀层保护光纤、化学镀+电镀层保护光纤,对嵌入效果进行了比较.采用拉伸试验的方法对嵌入强度进行了测试;采用光检测计检测了嵌入后的光强损失.结果表明,纯铝箔可以做为光纤传感器金属封装的基体材料;化学镀加电镀的方法可以作为光纤保护方法;电镀光纤超声嵌入铝箔后光强损失0.22 dB;金属化光纤嵌入铝箔拉伸力达到45 N.更多还原

【Abstract】 For embedding fiber sensor in metal,ultrasonic welding of T2 copper and 1100(L4) aluminium were carried out,and the fiber sensor was embedded in copper and aluminium foil.For selecting the protection method for the fiber sensor,the embedded fiber sensors with bare fiber,fiber with chemical plating coat and fiber with chemical-electro plating coat were tested respectively.The embedding strength of the fiber was evaluated by the tensile test and the light intensity loss of the embedded fiber was evaluated by the light detector.The results show that aluminium foil could be used for embedding the fiber sensor.Chemical-electro plating method could be used as the protection method for the fiber sensor.The average embedding strength was 45 N and the light intensity loss was 0.22 dB.更多还原
