Composite Curing Process Nondestructive Evaluation
Abstract
The objective of this program was to develop nondestructive evaluation techniques that can be used for in-process monitoring of the 350F carbon/epoxy cure cycle. The techniques developed should have the capability of measuring composite material properties that can be used as a real time measure of the state of composite cure. Fluorescence Optrode and Acoustic Waveguide sensors were selected for development as cure-monitoring techniques. Miniature pressure sensors were also evaluated for tracking laminate resin hydrostatic pressures. Development efforts undertaken to establish optimum sensor responses, evaluate sensor-laminate interface methods, establish factory-capable data acquisition and presentation systems, determine sensor response-material property relationships, and demonstrate sensor capability for monitoring typical autoclave composite cure cycles are described. Keywords: Composite; Cure cycle; Monitoring techniques; Cure parameter; Cure sensor; Fluorescence optrode; Acoustic waveguide; Pressure sensor; Data presentation.
