| 摘 要： | Static and fatigue tests under compression
load were made on impacted AS4/PEEK and T300/913C graphite/epoxy with ［45/90/-45/0］5S
stacking sequence. The comparison of the damage tolerance assessment for thermosetting and
thermoplastic composites shows that thermoplastics are more damage tolerant under
compression. Impacted thermoplastic composites have excellent compression-compression
fatigue behavior. The damage growth life is only a few percent of their total fatigue life
and no regular damage growth can be found. Some design principles for thermosetting
composite structures may still be used.
