Abstract

The present invention relates to a method for the manufacture of fibre-reinforced plastic components in moulds (13), in conjunction with which moulding material in the form of fibres impregnated with resin, after pressing or blowing into the moulds (13) and after hardening and cooling for a certain period in the mould, are removed as finished components. The moulds (13) are transported continuously on an endless track (1) between an input station (2) at which the moulding material is introduced into the mould and an ejection station (3) at which the finished component is ejected from the mould. Characteristic of the invention is that the transport speed of the moulds between the aforementioned stations (2; 3) is selected so that the transport period for a single mould is approximately the same as the hardening and cooling period for the eventual component in the mould. The reinforcing fibres are arranged in a bundle (4a) and are conveyed at the transport speed towards the input station (2). The fibre bundle (4a) is impregnated successively with the resin, is pre-heated, and is introduced into the input station (2) and into an opened mould (13). The mould is closed, and the moulding pressure or the blowing pressure is applied, whereupon the component is ejected at the ejection station (3) after the aforementioned hardening and cooling.

Description

Method and arrangement for the manufacture of components from fibre—composite materials in moulds
The present invention relates to a method for the manufacture of components from fibre—composite materials in moulds, in conjunction with which a moulding material consisting of fibres impregnated with resin, after pressing or blowing into the moulds and after hardening and cooling for a certain period in the moulds, is removed as finished components, and in conjunction with which the moulds are transported continuously on an endless track between an input station at which the moulding material is introduced into the mould and an ejection station at which the finished component is ejected from the mould. The invention also relates to an arrangement for the manufacture of components from fibre— omposite materials in moulds by the blowing or pressing of a moulding material in the form of resin—impregnated fibres, comprising transport devices so arranged as to transport the moulds at a certain speed between an input station at which the moulding material is introduced into a mould and an ejection station at which the finished components are ejected from the mould.
Introduction
Two types of fibre—composite materials are encountered: reinforced plastics, in which glass fibres, often of relatively short length, reinforce a plastic material; and so—called advanced fibre—composites, in which long fibres, preferably made of glass, carbon or polyamide, joined together by a plastic, give the material its principal characteristics.
Components manufactured from the reinforced plastics can be produced relatively efficiently, although they do not exhibit such good characteristics as components made from the advanced f bre—composites. The methods of producing the advanced fibre—composites are, with certain execeptions, slow and costly. The exceptions are the fibre—winding and profile-drawing operations. However, these methods impose severe restrictions on the choice of geometry available in conjunction with the manufacture of the components. Rather more freedom in the choice of geometry is allowed by the pull— oulding process, although this requires the cross—sectional area of the components to be maintained constant.
The fibre— omposite materials permit the manufacture of components with potentially very good characteristics with regard to high rigidity, high rupture limit, and low weight. In order to be of any interest, however, the material characteristics which are typical of the advanced fibre— omposites must be' capable of being utilized. The manufacture of components must be possible rapidly and in large series. The method of manufacture must permit the greatest possible freedom in the choice of geometry for the components.
The object of the present invention is to make such a rational method of production possible. This is achieved by the transport speed of the moulds between the aforementioned stations being selected so that the transport period for a single mould is approximately the same as the hardening and cooling period for the eventual component in the mould, by the reinforcing fibres being arranged in a bundle and being conveyed at the transport speed towards the input station, by the fibre bundle being impregnated successively with the resin, thus producing the moulding material, by the thus produced moulding material being pre—heated, by the pre—heated moulding material being introduced with the fibre bundle unbroken into the input station and into an opened mould, by the mould being closed, and by the pressing or blowing pressure being applied, whereupon the component is ejected at the ejection station after the aforementioned hardening and cooling.
A manufacturing arrangement which operates in the manner in accordance with the invention is characterized in that the aforementioned transport devices are so arranged as to produce a transport speed such that the transport period for a single mould between the input station and the ejection station is approximately the same as the hardening and cooling period for the eventual component in the mould, and in that the arrangement additionally comprises: devices so arranged as to open the mould prior to ejection of the plastic component at the ejection station and as to close the mould after the moulding material has been introduced into the mould, and as to generate the necessary pressure inside the mould during the moulding operation; a stock of reinforcing fibres in the form of threads; devices so executed as to arrange the reinforcing fibres into a bundle and as to transport the fibre bundle towards "the input station; devices so arranged as to impregnate the fibre bundle with the resin and as to pre—heat the thus impregnated bundle of fibres, and as to introduce a suitable length of the impregnated- and pre—heated fibre bundle into an opened mould at the input station; and devices for the application of a moulding or blowing pressure inside the mould.
In accordance with a first particular characteristic feature of the invention at least one part of the bundle of fibres is utilized for the transport of the moulding material, thereby economizing on the cost and the space required for transport devices of a more conventional kind. The desired continuity of manufacture is also achieved.
In accordance with a second particular characteristic feature of the invention the bundle of fibres is imparted with an appropriate cross—section having regard for the section of the component, and before arriving at each mould, a core or a pre—form is introduced into the bundle of fibres and is transported with it, preferably after the bundle of fibres has been impregnated. This means that every individual component is afforded the optimum distribution between plastic and fibre reinforcement, having regard for its varying cross—section. The method in accordance with the invention for the manufacture of a component from fibre—composite materials will be appreciated from the following description of an arrangement which operates in the manner to which the invention relates, with reference to the accompanying drawing, in which Fig. 1 illustrates schematically an arrangement for the manufacture of components from f bre—composite materials in the manner to which the invention relates. Fig. 2 illustrates schematically a cross—section through a component. i e
Fibre raw material in the form of fibres, roving or woven fabric fs* kept in a fibre store 4. A fibre bundle, generally designated as 4a, runs out from coils 4b or similar in the fibre store 4, and is so arranged as to run in an appropriate fashion having regard
15 for the shape of the component which is to be manufactured, into a fibre alignment device 5 and on to a coring station 10, at which the bundle 4a, if necessary for the component which is to be manufactured, is provided with a core, bubble or fibre pre-mould. The fibre bundle 4a is impregnated beforehand with a resin in an
20 impregnation bath 6. The fibre bundle and the resin are toghether designated as the moulding material. This is pre—heated at a pre—heating station 7. The thus pre— eated moulding material is then introduced into an input station, generally designated as 2, and into moulds 13 which, by means of transport devices 1, are
25 transported at a certain average speed between the input station 2 and an ejection station 3 at which the finished components are ejected.
The aforementioned transport device 1 consists of two transport 30 tracks 1a, 1b, which transport mould halves 13a and 13b, and which, between the input station 2 and the ejection station 3, run in parallel with the respective mould halves joined together, as illustrated schematically in Fig. 1.
35 Devices are also present which are so arranged as to close the mould halves 13a, 13b after the moulding material has been introduced into the mould, and as to open the mould prior to ejection of the finished component. These devices are of a conventional kind and have accordingly been omitted from the drawing and are not described in any greater detail here.
5
Before reaching the input station 2, each mould half 13a, 13b passes pre—heating stations 14a, 14b at which the mould halves are brought to an appropriate temperature.
-|Q The invention is characterized partly in that the average speed of the transport tracks 1a, 1b is selected so that the transport period for a mould 13 between the input station 2 and the ejection station 3 is approximately the same as the hardening and cooling period for the eventual component in the mould. The invention is
15 also characterized in that the transport tracks 1a, 1b interact with at least a part of the. fibre bundle 4a in connection with the transport of the moulding material. Arranged before or after the ejection station 3 is a cutting stage 11 for cutting the fibre bundle 4a so that the finished components are separated from one 0 another. This cutting stage can be entirely omitted, if desired, for example if it is appropriate for the subsequent installation of the components for the components to be arranged in a strip one after the other.
25 A compressed air source 8 of a conventional kind is provided for the application of moulding or blowing pressure inside each mould. The aforementioned pressure has the task of producing positive pressure inside the moulds, so that the components are sufficiently free from pores after hardening. As previously
30 mentioned, certain components require a core, a pre—form or a bubble, which is introduced into the fibre bundle 4a at the station 6. For the purpose of producing a foam core, a foam source 9 of a conventional kind is connected to the input station 2. An air core is produced by a bubble, for example made of plastic
35 film, which is applied at the station 10 and is inflated with air from the compressed air source 8. Fig. 2 illustrates a component 12 in a mould 13. The component has a core 15, for example of air or foam, and is attached to the adjacent components (not shown in the Figure) by means of the fibre bundle 4a.
