“…This behavior is due to the hardening of the resin ( Fig. 4) and is caused by degradation of the interfacia l strength bet ween fiber and resin as pH concentration increases (K im and Lim, 1992 ;Kim and Lim , 1997).…”

“…Failure of Glass Fiber Reinforced Plastics (GFRP) in ocean structures such as floating structures, harbor facilities, yachts and minesweepers occurs due to the combined action of service load and sea water, but the study of their fracture behavior in sea water is unusual (Kim and Lim, 1997). Therefore, the purpose of this study is to describe a mode of fatigue crack growth behavior of GFRP in air and sea water.…”

This paper evaluates the fatigue fracture behavior of a chopped strand glass mat/polyester composite both in air and sea water. Bending fatigue(R=-I) was performed on dry and wet specimens, that is respectively in air and sea water. Where the pH concentration of sea water was controlled to 6. 0, 8. 2, 10. 0 and the wet specimens were immersed in the sea waters for 4 months. Throughout the tests, fatigue cracks both in the dry and wet specimens, tested in the air or sea water, occurred at the beginning of the cycle, followed by either of two regions: one decreasing and the other increasing as the crack growth rate increases.

In order to investigate the corrosion fatigue characteristics in the weld of multi-pass welded A106 Gr B steel pipe, corrosion fatigue tests were performed under the various stress ratios and 3.5 wt% NaCI solution at room temperature. The corrosion fatigue characteristic curves were represented using crack closure concept. The obtained results are as follows; when the load frequency is 1.0 Hz, the crack opening point is transited in the region of Kmax=20 -32 MPa'm 1/z. In the low stress intensity factor range, the crack opening point is higher than that in air. However, in the high stress intensity factor range, it is lower than that in air. In the cases of 0.1 Hz and 0.01 Hz, the crack opening point gradually decreases to Kr~n with Kmax increase.
