Experiment Description

Research Overview

  • Carbon Fiber Reinforced Plastics (CFRP) are lightweight materials which have good mechanical properties, and are used in spacecraft antennas and telescope reflector materials. However, the degradation data of the CFRP materials after exposure to the space environment for long period was not obtained in ground experiments. Therefore, understanding the process of degradation for CFRP is very important for evaluating its use in spacecraft structural components.
  • Mirrors made of CFRP are attached to the JEM-EF facility for long duration exposure to the space environment.
  • To realize the lightweight and high-precision CFRP constructed mirrors applicable in the wavelengths from submillimeter to optical, is essential for the antennas and telescopes of the next generation of astronomical and earth observation satellites.
