介绍了光纤多功能传感系统在玻璃纤维/环氧树脂复合材料结构固化过程中测量温度和压力的应用。该系统采用干涉测量原理来测量温度、压力、液体折射率和其他物理参数。光纤压力和温度传感器已被用于监测复合材料拉挤成型过程。由于传感器的微型尺寸、中高温耐受性、非金属结构以及对电磁和射频信号的固有抗扰性，该系统非常适合监测各种复合材料固化过程。

THE APPLICATION OF FIBEROPTIC MULTIFUNCTION SENSING SYSTEM MEASURING TEMPERATURE AND PRESSURE DURING THE CURING OF FIBERGLASS/EPOXY COMPOSITE STRUCTURES IS DESCRIBED. THE SYSTEM EMPLOYS INTERFEROMETRIC PRINCIPLES TO MEASURE TEMPERATURE, PRESSURE, REFRACTIVE INDEX OF LIQUIDS, AND OTHER PHYSICAL PARAMETERS. FIBEROPTIC PRESSURE AND TEMPERATURE SENSORS HAVE BEEN EMPLOYED IN MONITORING COMPOSITES PULTRUSION AND MOLDING. THE SYSTEM IS IDEALLY SUITED FOR MONITORING A VARIETY OF COMPOSITE CURING PROCESSES BECAUSE OF THE SENSOR'S MICROMINIATURE SIZE, TOLERANCE OF MODERATELY HIGH TEMPERATURES, NON-METALLIC CONSTRUCTION, AND INHERENT IMMUNITY TO ELECTROMAGNETIC AND RADIO FREQUENCY SIGNALS.
