Thermal Conductivities of Some Polymers and Composites

Report No. ARL-TR-8298
Authors: William A Spurgeon
Date/Pages: February 2018; 48 pages
Abstract: This report presents results of measurements in the 20–100 ℃ temperature range of the thermal conductivities (Kt) of epoxies, polyurethanes, and hydrocarbons of interest to the Army. The study explores the effects of different curing agents, water absorption, glass transition temperature, and toughening. The study also explores E- and S2-glass composites of the epoxies, including effects of volume fraction of glass and fabric style. The experimental results are compared to modeled results for Kt in composites.
