摘要

The conclusions are as follows: It has been found that the phenomenon decreasing of residual fatigue bending strength in the case of impacted-side compression appear greater than those in the case of impacted-side tension for the orthotropic composite laminates. In the case of impacted-side compression, fracture is propagated from the transverse crack generated near the impact point. At approximately 0.2% of moisture content, the phenomens of rapid strength decrease appear and the strength variations do not occur at a moisture content of over 0.2%. It is thought that impact-induced damages and hygrothermals have an affect on the phenomena of residual fatigue strength decrease to some degree.
