Abstract：Objective The effect of lunar dust adhesion performance by fiber surface characteristics were investigated for the lunar dust adhesion mitigation of spacesuits.Methods In this research,an adhesion test method under ultraviolet ray radiation in vacuum was developed to measure the adhesion quantity of simulated lunar dust on fiber materials.Based on the microscopic image of the fiber sample after test,the influence of conductive and surface energy characteristics of the fiber materials on the lunar dust adhesion performance was studied.Results The simulated lunar dust were activated under ultraviolet ray radiation,which induced an increase of the adhesion quantity of simulated lunar dust on fiber materials;Lower surface energy or higher conductive characteristics of the fiber was both beneficial to reduce the adhesion quantity of simulated lunar dust.Conclusion The static electric forces were likely to be the major forces between the fiber and the lunar dust under ultraviolet ray radiation in vacuum.In addition to reducing surface energy,improving conductive characteristics of the fiber was more beneficial to reduce the adhesion quantity of simulated lunar dust.
