Název v původním jazyce
Measurement of thermal expansion coefficients of unidirectional composites using strain gages
Popis výsledku v původním jazyce
The article focuses on a determination of a coefficient of thermal expansion (CTE) of unidirectional thick-walled carbon composite specimens. The CTE were determined using two measurement methods. Both methods are based on a measurement of thermal outputof resistance strain gages, installed on a stress-free specimen, which is subjected to the temperature change. The first method uses single strain gage, which is bonded to a specimen made of test material. Value of CTE is refined from measured thermal output using corrective equations. The second method uses a pair of strain gages, with one bonded to a specimen from a reference material, and the second to a specimen from the tested material. The specimen's CTE can be then calculated from the differencein expansion coefficients, which is equal to the unit difference in thermal output. Measured values of CTE were compared with values calculated analytically.
