Abstract

AbstractAn efficient and economical experimental apparatus has been designed and built which delivers a known radiant heat flux and simultaneously measures the in‐depth temperature profiles in polymeric materials. Test samples are maintained in a controlled environment and are heated radiantly by a silicon carbide heating element capable of producing heat fluxes up to 7.0 cal/cm2‐sec. The experimental data produced by this device are extremely accurate and therefore are suitable for use in verification of numerical models. The utility of the apparatus was demonstrated by measuring temperature profiles to approximately 1000°C in a glass‐filled phenol‐formaldehyde resin.
