Estimating the term…
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 according to 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, a fiber-reinforced plastics material is heated locally, and further plastics material is applied by injection. This produces a particularly good coherent bond between the further plastics material and the fiber-reinforced plastics material. Ease of handling is also provided. The invention relates to a component produced according to the process and also to an apparatus for carrying out the process.
Process for the bonding of a fiber-reinforced, sheet-type, thermoplastic material to a further plastics material, said process comprising heating regions of the fiber-reinforced, sheet-type, thermoplastic material at which said further plastic material is to be bonded, but not the entirety of the fiber-reinforced, sheet-type, thermoplastic material, to temperatures above the melting point of said thermoplastic material, and injecting said further plastics material into one side said regions heated above the melting point of said thermoplastic material to press outward on the side opposite said one side.
