Possible mechanism of creep under internal pressure in laminated rings made of composite material

  • Published:
Polymer Mechanics Aims and scope

Abstract

The authors discuss the deformative susceptibility of a ring made of spirally arranged armature layers and a polymer binder. They show that in prolonged stress on these rings by internal pressure under conditions of a highly pliable matrix additional deformation may occur, caused by sliding of the coils.
