Effect of Fire-Retardant Coating and SiC Powder Filler on Thermal Properties of Green-Poxy Bio-Based Composites

In the present work, the thermal and kinetic characteristics of bio-epoxy composites under an oxidative atmosphere are investigated. The main objective is to evaluate the thermo-mechanical behavior of such materials for heat exchange purposes in aggressive/corrosive media. To this end, two parameters have been selected to describe the effect of (1) the fire-retardant coating as fire protection, and (2) the SiC powder as a filler for thermal conductivity improvement. Several samples were first manufactured by Vacuum Bag Resin Transfer Molding (VBRTM) process and then analyzed by thermogravimetric analysis under oxidative atmosphere. Comparison results highlight the proposed fire-retardant has a beneficial effect in terms of fire protection. In addition, the SiC powder charge has great potential for thermal conductivity enhancement without impacting the mass loss rates.
