A Novel Method to Quantify Self-Healing Capabilities of Fiber-Reinforced Polymers

Véronique Michaud, Amaël Maximilien Cohades, Robin Samuel Trigueira, Cecilia Scazzoli

The present work investigates a novel and practical method to evaluate the healing efficiency of carbon-reinforced polymer composites. The method should be representative of damage occurring during the lifetime of a composite part, should tend to damage th ...

Studies on Traction Separation Relations in Fracture of Layered Composites

Georgios Pappas

Layered fiber reinforced composite materials are prone to fracture in planes parallel to the direction of fibers leading to extensive delamination or intralaminar fracture. This phenomenon of crack propagation is frequently accompanied by significant incre ...
