Internal friction and Young's modulus have been studied on glass cloth reinforced plastics in the temperature range of 130 to 350 K. The temperature dependence of internal friction shows difference between the matrices. The strain amplitude dependences are also measured on variously fatigued specimens. The degree of fracture in interlaminar can closely relate to the strain amplitude dependences.
