Abstract
The effect of temperature on fatigue properties of a plain weave glass fabric reinforced plastics(GFRP)under tension/ torsion biaxial loading was studied. Fatigue tests were conducted at several terperatures between -23 and 60°C. The biaxial loads were proportinally applied to specimens. Although the static strength of GFRP at elevated terperature was lower than that at room and low terperatures below 0°C, the fatigue life at 60°C was longest when the specimens were subjected to a tension/torsion biaxial stress combination whose maximum cyclic stress normalized by the static strength at each temperature was constant for all tests.The primary fatigue damage at elevated temperature was meta-delamination occurring at cross-over points between wefts and warps. No meta-delamination was observed in the specimens tested at temperatures below 0°C while matrix cracks propagating across fiber bundles were formed. The modulus decay of GFRP in shear was greatly influenced by internal fatigue damage such as meta-delamination and matrix cracking more than the modulus decay in tension.
