...Guillermo Ramirez; Michael D. Engelhardt; Timothy J. Fowler This paper proposes a method for determining endurance limits to leakage for fiberglass pipes under internal pressure using acoustic emission signals and static pressure tests. Results are presented from a series of cyclic internal...

... and fiber orientation. Load versus tensile strain behavior for 0 and 90 deg oriented fiber specimens fabricated with 411–350 resin is shown in Fig. 12 . 12 Load versus micro-strain, 411–350 oriented fiber specimens A total of 22 nominally identical fiberglass specimens were tested...
