Thermal Expansion of Glass Fabric-Epoxy Composites at Cryogenic Temperatures

摘要: Thermal expansion is a crucial parameter for the selection of material to be used along with any other materials in cryogenic system. This paper presents analysis such data obtained by very precisely controlled experimental setup using 3‐terminal capacitance method. The measurements are carried out E‐glass fabric‐epoxy samples 32.5%, 35.2%, 39.2% and 48.9% fibre concentration at perpendicular fabric direction. results show that coefficient thermal (α) decreases increase but increases temperature. At 30K, α about 32% when from 32.5% 300K, it 50%. Quantitative comparison composites done stainless steel epoxy. It observed concentration, 6% 50% 45.6% 72.6% 30K 250K respectively. An attempt made prepare composite wi...
