COMPOSITE PIPE STRUCTURES HAVING HIGH CONTAINMENT AND AXIAL STRENGTH

摘要

Composite laminated fiber reinforced plastic pipe (1) having improved resistance to micro-cracking and delamination is disclosed. The pipe is composed of a plurality of laminated layers (2, 3, 4) forming the pipe wall structure, including an outer axial bearing layer containing reinforcing continuous fibers (5) embedded in a thermoset resin binder and disposed at an angle of 0 DEG up to +/- 30 DEG with respect to the longitudinal pipe axis and an inner layer in contact with the inner surface of the outer layer in containing reinforcing continuous fibers embedded in a thermoset resin binder and disposed at an angle of greater than +/- 30 DEG with respect to the longitudinal pipe axis.
