✦ Synopsis

TORAYCA T300 3K" is a two and a half dimensional woven carbon fiber reinforced epoxy which was developed for various applications including cryogenics. "Scaling" experiments in tension, in the shear-mode (mode II) and in the crack-opening-mode (mode I) were made at room and low temperature, in order to establish suitable sample geometries for irradiation experiments. Moreover, the interlaminar and the intralaminar shear strength as well as the ultimate tensile strength were investigated after irradiation at 340 K with a reactor spectrum up to a fast neutron fluence of 5 x IO** m-* (E>O.l MeV). The irradiated material was measured at 77 K and acoustic emission (AE) investigations were made for the tensile and the mode II samples.
