Abstract
Method which is intended for producing an endless semi-finished product and having the following steps: feeding a silicone tube and a separate internal conductor, wherein the internal conductor runs in a first interior space formed by the silicone tube; encasing the fed silicone tube by production of an endless fibre tube, which encloses the silicone tube from the outside. The silicone tube is expanded so that a gap is formed between the silicone tube and the endless fibre tube. A matrix material is feed into the gap connecting the silicone tube and the endless fibre tube by virtue of the matrix material being cured.
Claims9
A method for producing a continuous semifinished product, which comprises:
- supplying a silicone hose and a separate inner conductor in a first step, wherein the inner conductor runs in a first interior space formed by the silicone hose, wherein the silicone hose is produced by extrusion and wherein the separate inner conductor is introduced into the first interior space formed by the silicone hose;
- subsequently in a second step after the first step, encasing the silicone hose by producing a continuous fiber hose that encloses the silicone hose and the separate inner conductor on the outside;
- spreading open the silicone hose by a mechanical spreading device comprising a plurality of rolls distributed over a circumference which can bear against an inner side of the silicone hose, so that a gap is reduced between the silicone hose and the continuous fiber hose;
- supplying a matrix material into the gap;
- and
- bonding the silicone hose and the continuous fiber hose by hardening the matrix material.
A device for producing a continuous semifinished product, comprising:
- a conveying device for supplying a silicone hose and a separate inner conductor arranged inside the silicone hose, wherein the inner conductor runs in a first interior space formed by the silicone hose, wherein the silicone hose is produced by extrusion and wherein the separate inner conductor is introduced into the first interior space formed by the silicone hose;
- a bonding device for bonding a plurality of fibers to form a continuous fiber hose, and for encasing the silicone hose with the continuous fiber hose, the continuous fiber hose enclosing the silicone hose and the separate inner conductor on the outside;
- a mechanical spreading device, comprising a plurality of rolls distributed over a circumference which can bear against an inner side of the silicone hose, for opening out the silicone hose so that a gap is reduced between the continuous fiber hose and the silicone hose;
- a supplying device for supplying a liquid bonding agent into the gap;
- and
- a crosslinking device for crosslinking the bonding agent and for bonding the silicone hose to the continuous fiber hose.
