Investigation of fracture behavior of a composite crack arrestor

Erol Sancaktar, The University of Akron


This report summarizes an investigation into the mechanical fracture of a pipeline sleeve to be utilized as a crack arrestor. The sleeve, intended for commercial use, is a filament- wound unidirectional E-glass/polyester composite as determined by our spectroscopic and microscopic analysis. The tensile stress-strain and fracture behavior of the crack arrestor are evaluated both in-situ and also by using the ASTM standards E:399-81 and E:23-82.
