구리입자/메타아라미드 수지 복합재료 도포 스테인리스 철판의 적외선 방사 특성

다국어 초록 (Multilingual Abstract)

As a part of studies to lower the infrared (IR) emissivity from the surface of exhaust nozzle in the turbo jet engine, stainless steel plate was coated with copper particle/meta-aramid resin composites and the IR emissivity of the plate were investigated. Binders of filler particles based on synthetic polymers generally undergo thermal decomposition before 300℃. It was found that the meta aramid resin was thermally stable after the test at 320℃, confirming the excellent thermal stability. Contents of copper particles in the composites were varied from 0 to 70% by volume. It was observed that the copper particle/meta aramid resin composites showed good adhesion after the tests at 320℃. The specimen coated with the composite containing 50 vol% of copper particles showed the lowest IR emissivity, 0.6, at 320℃.
