Abstract
: Moisture absorption and desorption by a matrix resin, and the resulting deformation, havea criticaladverseeffect on theshapestabilityofcarbon fiber reinforced plastic space struc-tures. This study evaluates the effect of the moisture content in prepreg sheets on the life-cycle behavioroftheprepreg-basedcarbonfiberreinforcedplastic.Afterevaluating themoistureabsorption and desorption characteristics oftheprepreg sheets,thecure-induced strain and themoisture absorption and desorption deformation were measured using embedded optical fiber sensors. Furthermore,in order to investigatetherelationship between themoistureabsorption and desorp-tionbehaviorsandthechemicalstructureofthematrix resin,theresinstructurewasanalyzedusing Fouriertransform infrared spectroscopy.Becauseabsorption and desorption aredependent on the matrix resin, two types of resin were evaluated, an epoxy resin and a low moisture absorption cyanateresin.Finally,recommendationsformanufacturing andoperationaremadewithrespectto maintaining thelong-term shapestabilityofcarbon fiber reinforced plasticspacestructures.
