结构参数对石英纤维针刺毡防隔热和力学性能的影响
Effects of Structural Parameters on Thermal Insulation and Mechanical Properties of Quartz Fiber Needled Felt
摘要
Abstract
In order to develop high-performance quartz fiber felt with good thermal insulation and mechanical properties,the effects of the thickness of quartz fiber felt on its thermal insulation performance were predicted based on the mathematical equation of heat transfer.To improve the mechanical properties of fiber felt,the influence of adding different layers of quartz fiber cloth to the fiber felt on its mechanical properties was investigated Additionally,the influence of needle-punched density on the thermal insulation and mechanical properties of quartz fiber felt was also discussed.The results show that the simulation temperature of quartz fiber felt has a good agreement with the experiment,with the calculation accuracy is up to 94.8％.The thermal insulation performance improves by about 20℃ when the thickness of the quartz fiber felt is increased by 2 mm.Adding quartz fiber cloth significantly improves the breaking strength and tearing strength of fiber felt.However,excessive needle punched density reduces its mechanical properties and damage the structure of fiber felt.关键词
