Research on Strain Gauge Protecting-Process to Measurement Data Accuracy of Composite Material Structure

Abstract:

With the extensive application of composite materials in aircraft structure, the test technologies of strain gauge are more important. But the installed strain gauge must to be protected against some influence. Because the protecting-process of strain gauge affected the strain measuring results of composite structure. In this paper, the composite (T700/LT-03A) was selected to made specimens, and the three different protective agents: protective glue, protective grume and protective grummet were adopted. In order to identify influence of the different protecting processes on the measuring data accuracy, comparison of repeatability and linearity before-and-after measured strain data are served as test standard. The compared test results show that the different strain protecting processes adopted in strength test can make different results of the measuring data accuracy.
