Metals vs. composite materials

Comparison of fatigue strength

Metals and composites behave differently

under fatigue loading.

Composite materials exhibit a better resistance to fatigue compared to metals.

Comparison of fatigue strength of different composites Due to the variety

Comparison of fatigue strength of different composites

Due to the variety

of configurations (types of fiber, resin and lay up) composites are not totally sheltered from fatigue damage.
