Thermal Conductivity Research Paper Database Thermtest has compiled the world’s largest thermal conductivity academic paper database. All research papers are searchable by method, authors, keywords, and titles. The research paper database is dedicated to the Transient Plane Source (TPS), Transient Hot Wire (THW), Transient Line Source (TLS), and...
This article investigates the effects of two types of nanoparticles, OctaMethylOligomericSilsesquioxanes (OMPOSS) and carbon nanotubes (CNTs), in a model epoxy resin. Intumescent phosphorous-based flame-retardant (APP) was also incorporated with the CNTs. Thermal conductivity of nanocomposites was measured using a thermal analyser with the transient plane source method. Epoxy with APP and OMPOSS had increasing thermal conductivity below the glass transition temperature (Tg) but slowed above Tg. When APP and CNTs were combined, CNTs hid the effects of APP, leading to a decrease in thermal conductivity.
Carbon foams are novelty materials that have a wide range of applications such as radiators, thermal protection, and fire-resistant cores. The main carbon sources of carbon foams are sucrose, coal, coal tar pitch, and petroleum pitch, however the foams that use sucrose as their primary source have low thermal conductivity. This paper examined the thermal properties of carbon foams derived from sucrose but used graphite fillers to improve thermal conductivity. The TPS instrument measured the thermal conductivity of the carbon foam samples using the transient plane source (TPS) method. Results showed that with the addition of the crystalline graphite filler, the thermal conductivity of the carbon foam increased substantially.
Three reference passive fire protection materials were tested to determine the effect that fire exposure has on their thermophysical properties. It was determined that the thermophysical properties during fire exposure have a significant impact on the performance of the materials. The knowledge of how the properties of these materials change upon exposure to fire will aid researchers in being able to better calculate the time to failure of the object the material is protecting.
