文摘
- •
Biaxial fabric prestressing of E-glass/polyester composite system was employed to enhance composite fatigue life.
- •
Optimum prestressing level can prolong fatigue life of the composite when normalized peak stress is below 0.6.
- •
Over-prestressed fabric was a critical choice and not recommended, especially for samples loaded at off-axis direction.
- •
The benefits drawn from employing the prestressing method could recede with increasing the off-axis fabric orientations.
