Abstract: A degradable composite comprising a degradable matrix, a first fiber type and a second fiber type, wherein the first fiber type has a different rate of degradation to that of the second fiber type.

Abstract: A fully biodegradable fibre reinforced composite adapted for use as a medical implant which is shaped and processed by means of a resin reaction injection transfer molding process adapted for predetermining shape, physical properties and degradation profile, shaped preform and/or composition for preparation of the shaped composite, process for the production of the shaped composite comprising obtaining a shaped preform and impregnating with resin with simultaneous processing thereof, shaped composite comprising thermoplastic matrix and fibres adapted for use as a medical implant, characterised by a differential degradation of matrix with respect to fibres adapted to degrade via an intermediate shaped structure comprising residual porous matrix or residual fibre form respectively and selection of composite is made for primary growth of a preferred cell type, throughout voids created by degraded matrix or fibre respectively, according to the desired healing or reconstruction locus, the shaped composites for use

Abstract: In resin transfer molding, each mold cavity is charged initially with a hot curing resin system, then while the first resin is still uncured, successively injecting one or more resin systems which push the previous systems to the periphery of the mold. Each of said successive resin system curing at a lower temperature then the preceding system. Thus each resin system cures progressively faster than the previously injected resin system such that all resin systems cure at substantially the same point in time.
