Emissivity of silicone rubber
WebDec 4, 2024 · The thermal emissivity is ∼0.88 independent of moisture content for the fabrics polyester, cotton, and nylon, while acrylic shows a pronounced increase in thermal emissivity as moisture content increases, ranging from ɛ ∼ 0.81 at low humidity conditions to ɛ ∼ 0.88 under high humidity conditions. In this work, emissivity measurements ... Webpresent the emissivity values measured for some of these materials. There is much of interest in the possible use of carbon fiber reinforced silicon carbide composite materials for hot structures and thermal protection systems [1, 2]. Emissivity measurements made on C/SiC during the NGLT program will be compared to more recent measurements.
