The authors examine the melting and crystallization behavior of a polyethylene/boron nitride composite to understand an unexpected exothermic peak when the BN content was greater than 10 wt. %. Based on these observations, an optimal annealing temperature of the composite was investigated to enhance its thermal conductivity. The appearance of the peak was determined to depend on the different nucleated capability of the different BN aggregates in local area. An annealing ...
This report is a comprehensive compilation of a variety of studies performed on rock in a borehole at a potential nuclear waste storage facility in Sweden. Density, water absorption, mineral composition and thermal properties were studied to determine the site's suitability as a safe storage area. Thermal properties are an important factor since the nuclear waste canisters will continue to give off heat in storage due to nuclear fission, and ...
Carbon nanotubes (CNTs) have extremely high thermal conductivity and can raise the thermal conductivity of a polymer matrix when used as an additive. Previous research has shown that random CNT orientation in polymer matrices gives a much lower thermal conductivity value than a specific alignment direction. This project tested the thermal conductivity of oils and polymers. Results were encouraging, with the thermal conductivity of the composites increasing linearly with the ...
In this study, the insulating properties of building materials made out of recycled plant particles were tested with both the laser flash method and the Transient Plane Source (TPS) method. The tests were conducted with aggregates of sunflower pith with particle sizes 1, 1.5, and 2.5 mm, to see how the thermal conductivity behaves with increasing air volume fraction between grains. The TPS method produced values with an increasing trend for thermal conductivity ...
Preventing steel from losing its strength during fires is crucial for safe evacuation and effective fire fighting. One of the most common protective coatings applied to steel and other construction materials today is intumescent paint. In this study, researchers created a potential new protective coating using a curable silicone base and varying volume amounts of expandable graphite between 5-25%. The key characteristic of these coatings is that they swell to ...
