- A study on the aging phenomenon of CFRP (Carbon fiber reinforced plastic) used for satellite skin and GFRP (Glass fiber reinforced plastic) composite material used for PCB (Printed Circuit Board) due to exposure to the space environment is in progress

- Applying the acceleration technique, a study is underway to derive an acceleration model of a specimen with failure, which is a functionally unusable state due to aging
