Effect of Matrix Properties on Quasi‐Static and Fatigue Properties of Thermosetting Polyurethane and Its GFRP Composites

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 5, Page 1929-1943, May 2026.
ABSTRACT In this study, the influence of resin cross‐link density on thermomechanical properties and fatigue behavior of polyurethane resins and glass fiber‐reinforced polyurethane (PUR‐GFRP) composites was investigated. This material is a candidate for renewable energy applications like rotor blades in wind turbines.
