Abstract

The through‐thickness thermal conductivity of polymer composite molds has a strong effect on out‐of‐autoclave manufacturing operations. Limited thermal conductivity and variability data is available for composites made from carbon fibers that are widely used in mold and aircraft construction. This article presents in‐plane and through‐thickness thermal conductivity data for structural carbon fiber polymer composites made from three types of reinforcements. Variability is quantified in all cases. Techniques for the predictive modeling of through‐thickness transverse thermal conductivity are assessed. Effects of variations in model geometry on conductivity are quantified. Conclusive observations on variability and recommendations on modeling techniques appropriate for the different reinforcements are made. POLYM. COMPOS., 2010. Β© 2009 Society of Plastics Engineers

## Abstract The electrical and thermal conductivity of nanocarbon filled polymers were studied by adding nanocarbon fillers (thermoexfoliated graphite (TEG) and dispersed TEG (nanoTEG)) to epoxy resin (ED) or polyethylene oxide (PEO). The content of filler in composite materials (CM) was (0.5–10) w
