Natural rubber/graphene (NR/GE) composites were prepared by ultrasonically-assisted latex mining and an in situ reduction process, followed by latex coagulation to obtain the masterbatch. It was determined that this method of preparing the NR/GE composites resulted in an increase in tensile strength when compared to conventional direct mixing. A variety of properties of the composites were investigated, including: thermal conductivity, thermal diffusivity, specific heat, maximum torque, crosslink ...
Microencapsulated phase change materials (MPCMs) are excellent materials for the storage of thermal energy, and through their dispersal into a carrier fluid, microencapsulated phase change slurries (MPCS) can be prepared. These slurries exhibit both excellent thermal energy storage and heat transfer properties. A series of MPCS were prepared for this research and subsequently tested for thermal conductivity and specific heat. Other methods of quantification include DSC, TGA, rheometry, and infrared ...
The goal of this study was to obtain information on thermal properties of three types of concrete over a wide temperature range (20°C to 800°C). The three types of concrete are: high-strength concrete (HSC), self-consolidating concrete (SCC) and fly-ash concrete (FAC). The thermal data collected included thermal conductivity, specific heat and thermal expansion of the concrete samples using the TPS method. The effect of steel, propylene and other hybrid fibers ...
The thermal and mechanical properties of 4 different types of concrete were studied in the temperature range of 20°C to 800°C. Thermal properties studied include: thermal conductivity, specific heat and thermal expansion. Data generated from the testing of these samples using the TPS method were used in order to generate simplified expressions of thermal and mechanical properties as a function of time....
The thermal properties of a series of treated and untreated oil palm fiber-reinforced composites were tested at room temperature and atmospheric pressure using the TPS method. Treatment of the composites with varying methods resulted in increases in thermal conductivity, porosity and pore sizes depending on the treatment method used. The dependence of thermal conductivity on temperature was also studied and it was found that the maximum thermal conductivity was at ...
