DOPAMINE-COATED UHMWPE/HYDROGEN-RICH BENZOXAZINE COMPOSITES FOR SPACE RADIATION SHIELDING

J.-H. Cha¹, C.-G. Kim¹; ¹KAIST, South Korea

Recently, COTS(commercial off-the-shelf) is being used as an electronic device for high performance and low cost of satellites. However, COTS is vulnerable to cosmic radiation. UHMWPE/hydrogen-rich benzoxazine composite(UHC) has excellent cosmic radiation shielding performance. A study was conducted to improve the mechanical properties of UHC and prove that it can be used as a satellite material.
