ABSTRACT:
A completely bioabsorbable reinforced composite material for use in medical implants and a method for making same. The composite material comprises a hybrid yarn of intimately co-mingled reinforcement fibers of a crystalline polymer and matrix fibers of a polymer having a glass transition temperature below the melting point of the crystalline polymer. The hybrid yarn is heated under pressure to a processing temperature between the glass transition temperature of the matrix fibers and the melting point of the crystalline polymer to form a continuous matrix with reinforcing fibers of crystalline polymer. The composite material may be formed by a two step consolidation process.
