Multi‐scale experimental investigation of porosity‐induced damage effects in filament‐wound carbon fiber reinforced epoxy composites used in hydrogen storage tanks
Porosity, measured in the range of 5%–7%, significantly affects mechanical performance, reducing Young's modulus by up to 40% between ±15° and ±30° fiber orientations and by 65% in multilayer structures.
Fiber/matrix decohesion and crack initiation due to porosity lead to the formation of transverse cracks and micro‐delaminations between layers, affecting the durability of the composite.
Optimizing fiber orientation and reducing porosity are critical to improving the mechanical performance and long‐term durability of hydrogen storage vessels.
