    摘要: A porous composite suitable for filling a recess or a through-passing hole in an implant. The composite includes particles A prepared from a bioactive material and particles B prepared from a non-bioactive material or weakly bioactive material, which is sintratable with the bioactive material, such that particles A and particles B have been sintered together to a porous composite. Particles A and particles B are essentially homogeneous in size. Also disclosed is an implant which contains a core and the composite.

    摘要: This invention relates to a shapable prepreg comprising fibers and a polymeric matrix. The polymeric matrix is a multiphase matrix comprising a first matrix component consisting of a monomer or a dendrimer, and a second matrix component consisting of high molecular weight organic molecules, said second matrix component forming a sticky membrane of the prepreg with an interpenetrating polymer network (IPN) bonding to the first matrix component. Preferably, the prepreg further comprises a third matrix component consisting of high molecular weight organic molecules, said third component being distributed between the fibers.
