Bovine pericardium (BP) has been used as leaflets of prosthetic heart valves. The are sutured on metallic stents and can survive 400 million flaps (~10-year life span), unaffected by the suture holes. This flaw-insensitive fatigue resistance is unmatched synthetic leaflets. We show that endurance strength BP under cyclic stretch insensitive to cuts long 1 centimeter, about two orders magnitude longer than a thermoplastic polyurethane (TPU). results from high collagen fibers soft matrix...
This study focuses on the microscopic processes of crack growth in a composite knitted fabric and soft matrix course direction under both monotonic cyclic stretching.
