Experimental and modeling of thermal and dielectric properties of aluminum nitride-reinforced polybenzoxazine hybrids

Compared to traditional epoxy, polybenzoxazine resins have improved thermal, mechanical, and electrical properties. In this article, spherical aluminum nitride (AIN) was studied as a filler in bisphenol A-aniline-based polybenzoxazine (poly(BA-a)). Thermal conductivity was obtained by transient plane source method. Thermal conductivity of each composite gradually increased with enhanced filler amount. Poly(BA-a)/AIN composites also had higher thermal conductivity than systems containing epoxy/AIN....

Reaction to fire of an intumescent epoxy resin: Protection mechanisms and synergy

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 ...

A Study of Thermal Conductivity of Boron-Nitride Epoxy-Matrix Composites

Thermal conductivity of neat-epoxy resin is one of the lowest among all known solid materials. A common method of increasing thermal conductivity is through the addition of filler particles with high thermal conductivity. In this study, epoxy resin composites were studied to assess the possibility of increasing thermal conductivity for effective heat dissipation. A typical industrial liquid epoxy was used with commercial boron nitride powders PT100 and PTX25 as fillers. ...

Behavior of intumescent epoxy resins in fireproofing applications

Intumescent epoxy resins are used commercially for fireproofing because of their ability to swell. The swelling action is initiated to shelter the materials beneath the resin from any potential heat source. In this study, the thermal degradation of the intumescent epoxy resins was researched, paying close attention to the morphology of the material and the overall swelling mechanism occurring. It was determined that the thermal degradation process inherently alters the ...

Effect of nanosized carbon black on the morphology, transport, and mechanical properties of rubbery epoxy and silicone composites

Rubber carbon black (CB)/rubbery epoxy (RE) and CB/silicone composites with different types, loadings, and silane functionalization of carbon black were prepared. These composites were investigated for their electrical conductivities, and their mechanical properties. The thermal conductivity of each composite was also determined using a thermal constants analyzer. It was determined that the incorporation of carbon black into the composites increased the thermal conductivity in all of the samples. ...
