Fatigue behavior of unidirectional fiber‐reinforced pultruded composites with high volume fiber fraction

Pultrusion is a high-volume manufacturing process for fiber-reinforced polymer (FRP) composites ensuring high strength and quality products. However, research studies are very limited on the fatigue behavior of these products, especially with unidirectional fiber alignment. This study investigates pultruded glass FRP (GFRP) volume fraction ( V f = 65 % $$ {V}_f=65\% ). Tension–tension loading was applied different levels stress, frequency, gripping condition until failure. Results showed that {V}_f have significantly low life cycle. Moreover, increasing frequency better resistance, while tabs geometry has insignificant effect dog-bone shaped specimens. Comparison available literature GFRP lower performance than those . A capacity reduction factor also proposed as function
