The present invention relates to a composite material comprising biocompatible and bioresorbable glass, a biocom-patible and bioresorbable matrix polymer and a coupling agent capable of forming covalent bonds. The composite is characterized in that it further comprises a compatibilizer, wherein at least 10 % of the structural units of the compatibilizer are identical to the structural units of the matrix polymer, and the molecular weight of the compatibilizer is less than 30000 g/mol. The invention also relates to the use of this composite, to a medical device comprising said composite and to a method for preparing the composite.
