Despite its fragility, poor thermal properties, and high water sorption rates, polymethyl methacrylate (PMMA) is commonly used in denture fabrication. This study aimed to examine how the addition of Aluminum oxide nanoparticles affected the properties of PMMA. A thermal constant analyzer measured the thermal properties of the Al2O3 nanoparticles using the transient plane source (TPS) method. Results showed that the thermal conductivity and thermal diffusivity of acrylic resin improved ...
Adding conductive fillers to polymer resins improves the thermal conductivity of the polymers. In this study, Thermocarb TC-300 synthetic graphite and Fortafil 243 carbon fiber were added to Vectra A950RX liquid crystal polymer (LCP) to produce anisotropic single and multiple filler composites. A Thermal Constants Analyzer measured the thermal conductivity of the composites using the transient plane source (TPS) technique. The formulations that contained Thermocarb fillers had higher in- and ...
The authors set out to prepare cellular vitreous carbon (CVC) foams with varying thermal and physical properties. This was accomplished by using tannin-based resin modified by different isocyanates in varying amounts. Three different experimental procedures were used to prepare foams with different physical and thermal properties. Physical properties of the foams studied include density, as well as pore volume, pore size and cell diameter. The transient plane source (TPS) technique ...
Thermal interface resistance results from small gaps and surface geometry mismatches between two materials that make up a composite. Thermal interface resistance is present in most any material that is comprised of two or more components. In the field of thermal interface materials, the majority of novel materials are composites, and thus are subject to thermal interface resistance and thermal boundary resistance (thermal discontinuity at a perfectly bonded interface of ...
