Join us at the International Thermal Conductivity Conference (ITCC) and the International Thermal Expansion Symposium (ITES).
In the building and construction industry today, weather resistant and flame resistant materials have become fundamental. As such, silicone coated materials have been intensively researched, as they increase a given materials resistivity to heat and flames. Due to complications and time constraints when testing coating technologies in a lab setting, more enforcement has been placed on numerical methods. Based on stitching patterns, geometry models of the material and heat transfer ...
In this paper silica aerogels were synthesized using solvent exchange and surface modification of wet gels from waterglass using IPA/TMCS/n-Hexane solution. The densities, porosities, and specific surface areas were measured. Three different mixing methods were employed to determine their effect on the thermal and mechanical properties of the aerogel. Thermal conductivity testing revealed thermal conductivity readings ranging from 0.03–0.12 W/m·K....
The thermal conductivity and thermal diffusivity of SRP (sisal-reinforced polyethylene), GRP (glass-reinforced polyethylene), and GSRP (sisal/glass hybrid fibre-reinforced polyethylene) were tested from 120 to 350K. Results showed variances in thermal conductivity values with varying temperatures in materials containing different orientations of sisal fibres. Due to the anisotropic nature of the SRP fibre, there is a difference in the thermal conductivity readings from the parallel to the perpendicular direction. The GRP ...
The Transient Plane Source Method is a helpful tool to test for the thermal conductivity of homogenous materials, however researchers at both the Chalmers University of Technology and Gothenberg University have created a process to test the thermal conductivities of inhomogeneous materials. For this experiment, a thermal analyzer was used to determine the thermal conductivities of four different sample materials (polymers and Pyrex glass) – each with different sizes and defects. ...
