The object of the invention is to develop inorganic-organic compound materials which overcome the disadvantages of the state of art, wherein inorganic-organic compound substances for biomedical purposes possess to a large extent specifically adjustable characteristics. Inorganic initial substances form a new solid chemical compound with organic initial substances. The inorganic initial component consists of a biocompatible silicate glass and/or a silicate glass ceramic of the system SiO.sub.2 -Al.sub.2 O.sub.3 -MgO-Na.sub.2 O/K.sub.2 O-F.sup.-, and/or a bioactive phosphate silicate glass and/or a phosphate silicate glass ceramic of the system SiO.sub.2 -Al.sub.2 O.sub.3 -MgO-Na.sub.2 O/K.sub.2 O-CaO-P.sub.2 O.sub.5 F.sup.- and/or of the system SiO.sub.2 -MgO-K.sub.2 O-F.sup.- -CaO-P.sub.2 O.sub.5, and/or a bioactive phosphate glass and/or a phosphate glass ceramic of the system P.sub.2 O.sub.5 -Al.sub.2 O.sub.Type: GrantFiled: June 12, 1986Date of Patent: March 15, 1988Assignee: Friedrich-Schiller-Universitaet JenaInventors: Werner Vogel, Guenther Heublein, Wolfram Hoeland, Manfred Boese, Karin Naumann, Gunter Carl, Juergen Vogel, Peter Wange, Jens Gummel, Peter Zinner, Eggert Beleites, Thomas Schubert

Patent number: 4727096Abstract: The invention relates to a composition of polymerizable resins reinforced with cut yarns of different lengths, such as glass yarns, and a process for its production. This composition comprises at least a representative of each of the following constituents: an unsaturated polyester, a thermoplastic polymer, a monomer liquid substance having at least a polymerizable reactive CH.sub.2 .dbd.C< group per molecule, an inert filler and optionally a thickening agent, a catalyst, an inhibitor and a releasing agent, the cut yarns being in the dispersed state in filament form for the longest ones, with the shortest yarns remaining in state of yarn formed from a multiplicity of filaments glued together. The process steps include making the mixture of the organic constituents and successively incorporating therein first the yarns previously coated with an insoluble lubricant, then the yarns coated with a lubricant which is soluble in the mixture.Type: GrantFiled: October 16, 1986Date of Patent: February 23, 1988Assignee: Vetrotex Saint-GobainInventor: Claude Choudin
