Join us at the International Thermal Conductivity Conference (ITCC) and the International Thermal Expansion Symposium (ITES).
Composite materials are materials made of reinforcing substances that are set in a matrix of polymers, ceramics or metals. This experiment measured the thermal conductivity of wood and ceramics, and explored the factors that influence the thermal conductivity. The Transient Plane Source (TPS) method was used because test times are relatively short compared to steady state techniques, and transient methods are not limited by the size, shape, or state of ...
The thermal conductivity of thin, high-conducting ceramic bars—commonly used in mechanical tensile testing—is measured using a variant of the short transient hot-strip technique. As with similar contact transient methods, the influence from the thermal contact resistance between the sensor and the sample is accurately recorded and filtered out from the analysis—a specific advantage that enables sensitive measurements of the bulk properties of the sample material. The present ...
Phenolic resin impregnation was combined with liquid silicon infiltration to create a carbon/silicon carbide composite. The potential application for this material is in disc brakes in vehicles due to their oxidation resistance and friction behaviour. The density of the composite was altered until a final value of 2.10g/cm3 was achieved. The thermal conductivity of the composite was measured using the TPS method, and was determined to be 48.72 W/...
This paper discussed the creation of ceramic foams with various amounts of agar added. The foams used fly ash as the raw material in order to make them more environmentally friendly. The authors hoped that this successful use of fly ash could help to recycle that vast amounts of it that are produced each year. The effect of the various agar additions on the thermal conductivity of the foams was ...
Zeolites are highly insulative, porous minerals. Due to their insulating nature, heat transfer and therefore thermal conductivity is greatly impacted. With the help of a transient plane source (TPS) thermal constants analyzer, researchers tested the ability of zeolites to conduct heat when containing thermally conductive additives. This research mainly focused on metallic, ceramic and carbonaceous additives. The research conducted has shed light on the design of new porous composites experiencing ...
