SiliconesLes silicones, ou polysiloxanes, sont des composés inorganiques formés d'une chaine silicium-oxygène (...-Si-O-Si-O-Si-O-...) sur laquelle des groupes se fixent, sur les atomes de silicium. Certains groupes organiques peuvent être utilisés pour relier entre elles plusieurs de ces chaines (...-Si-O-...). Le type le plus courant est le poly(diméthylsiloxane) linéaire ou PDMS. Le second groupe en importance de matériaux en silicone est celui des résines de silicone, formées par des oligosiloxanes ramifiés ou en forme de cage (wiki).

| Résumé : |
A novel composite structure consisting of load-optimized liquid silicone components and braided 2D structures will serve as an artificial cruciate ligament implant in the future. The development of this implant is a joint research project with partners from the Clinic for Accident and Reconstructive Surgery at the University Hospital of Aachen, Germany, as well as the Institute of Textile Technology and the Institute of Plastics Processing (IKV) at RTWH Aachen University. |

- Braiding structures improve the mechanical strength
- Good abrasion behavior due to LSR coating
- Evaluation of the mechanical properties of the artificial cruciate ligament
- FIGURES : 1. The artificial cruciate ligament consists of an LSR core braided with a 2-dimensional structure and an LSR coating - 2. Force-strain curves for braided structures without coating according to the hysteresis tests. The braid with LSR core meets the minimum requirements for strength and stiffness - 3. Test stand with frame and additional scrubbing position. The adaptation of the Benchlenbert test characterizes the abrasion behavior of the coated structures - 4. Micrographs of the artificial cruciate ligament after the abrasion test. Incontrast to the coated specimen, the braid in the uncoated speciment is severely damaged - 5. Comparison of the mechanical properties of the new artificial cruciate ligament with the native human cruciate ligament. The impregnation is inadequate with the three-fiber braid the two-fiber braid is much better |
