Title: Measurement of the thermal conductivity of composites using heat flow sensors
Abstract: Abstract A thermal conductivity measuring apparatus that uses heat flow sensors to measure the heat flux through samples was constructed of inexpensive materials. This device was used to measure the thermal conductivity ( k ) of two composites used in the space program that consist of fibrous or granular components embedded in a resin matrix. The k ‐values that were determined ranged from 0.035 to 0.059 Btu/h‐ft 2 ‐°F/ft (−163 to 553°F) and 0.029 to 0.035 Btu/h‐ft 2 ‐°F/ft (77 to 212°F). Thermal conductivity values of the composites conformed to the rule of mixture. The accuracy of the system was found to be comparable to the guarded hotplate and it requires neither a skilled operator nor extensive maintenance.
