The thermal conductivity of a mineral cast material made of epoxy-granite was determined by a steady state method, as well as by the transient plane source (TPS) method. In comparing both methods to geometric models, it was determined that both methods were able to accurately measure the thermal conductivity of the two-phase material. The material that was tested was intended to be used in machine tools, and so its thermal ...
The effective thermal conductivity of mineral cast epoxy granite materials with varying volume fractions of epoxy content was determined. This material was being studied for application as a structural material in high speed machine tools. Optimal materials for this application would have good chemical resistance and workability, a high strength-to-weight ratio, a low thermal conductivity, excellent damping properties, and they would be easy to produce. Eight samples with volume fractions ...
A novel replication technique for the fabrication of 3D microstructures was developed. A polished silicon wafer was transferred onto an epoxy composite. The thermal properties of the epoxy composite were investigated and compared to those of the pure epoxy. It was determined that not only was the thermal conductivity increased, but the epoxy composite also showed an improvement in mechanical properties over the pure epoxy....
The authors have investigated the use of silver nanomaterials as a filler in epoxy resin in an effort to identify a composite resin with a high thermal conductivity for application as a thermal interface material. It was determined that the addition of silver nanoparticle and silver nanowires both increased the thermal conductivity of the resin, but the silver nanowires caused a much more drastic increase. It was found that by ...
The reaction to fire properties of three commercial coatings designed for steel structures were investigated. The coatings in this study were covering a glass fiber-reinforced epoxy composite. It was determined that the thermal barrier effectiveness of these coatings was dependent on the degree of expansion and the thermal conductivity of the expanded char. Using these two parameters, the required thickness of a coating that can enable a structure to withstand ...
