Abstract

Abstract Translated from French Article en polymère d'acide lactique utilisable notamment comme prothèse biodégradable présentant à 23°C un module de rigidité en traction supérieur à 5000 MPa et une résilience en traction supérieure à 500 kJ/m² et un retrait thermique inférieur à 15 % à 130°C. L'article est réalisé par forgeage d'une ébauche à une température comprise entre 80 et 170°C, avec un taux d'étirage de 200 à 1000 %. Article in lactic acid polymer usable in particular as a biodegradable prosthesis having at 23 ° C a tensile stiffness modulus greater than 5000 MPa and a tensile resilience greater than 500 kJ / m² and a thermal shrinkage less than 15% at 130 ° C . The article is produced by forging a blank at a temperature between 80 and 170 ° C, with a drawing rate of 200 to 1000%.
