Patent number: 8617442Abstract: A process for the bonding of a fiber-reinforced material to an injection-molding material and an article produced by the process. The process improves the bond between a fiber-reinforced starting material and a material applied by injection. A further plastics material is inserted under pressure into a fiber-reinforced plastics material. This results in interlock bonding between the further plastics material and the fibers of the fiber-reinforced plastics material. This type of bonding is substantially more stable than known bonding.Type: GrantFiled: June 14, 2010Date of Patent: December 31, 2013Assignee: Lanxess Deutschland GmbHInventor: Ulrich Dajek

Publication number: 20080292858Abstract: The invention relates to a process for the bonding of a fiber-reinforced material to an injection-molding material. The invention further relates to an article produced by the process. It is an object of the invention to improve the bond between a fiber-reinforced starting material and a material applied by injection. To achieve the object, further plastics material is inserted under pressure into a fiber-reinforced plastics material. This results in interlock bonding between the further plastics material and the fibers of the fiber-reinforced plastics material. This type of bonding is substantially more stable than the bonding known from the prior art.Type: ApplicationFiled: November 20, 2006Publication date: November 27, 2008Applicant: LANXESS DEUTSCHLAND GMBHInventor: Ulrich Dajek
