This apparatus enables the student to study the characteristics of composite structures and its heat transfer ability across the composite walls by altering the combination of slabs. The apparatus consists of three slabs of different materials of same thickness. The slabs are brought together in contact. The three slabs are brass, M.S and asbestos. One surface of the slab is electrically heated and the other end is cooled, .the temperatures of the slabs are measured using thermocouples and are indicated by temperature indicator. The power Input to the heater is measured by Voltmeter and Ammeter.
