Abstract

A method of applying an open-work reinforcement member 12 to the surface of a plastic material 10 wherein said reinforcement member is embedded in the plastics material by the application of ultrasonic vibrations and mechanical pressure. In addition to serving as a reinforcement, the member 15 may also be utilised to join two pieces 13, 14 of plastics material together. It may also be adapted to serve some further purpose for example by carrying an eyelet 29 or a stud 18 which forms part of a two-part coupling. <IMAGE>

Description

SPECIFICATION Reinforcing or joining plastics materials This invention concerns reinforcing or joining plastcis materials by menas of an open-work reinforcement member which is embedded in the plastics material either where local reinforcement is required, or for the purpose of joining two pieces of such material in abutting relation. It will be understood that the reinforcement may be required at the site of a joint or elsewhere, or it may serve to establish such a joint.
The present invention resides in a method of providing a reinforcement to a plastic material, particularly but not essentially at the site of a joint in such material, comprising the steps of applying an open-work reinforcement member to the surface of a plastic material at the site of the desired reinforcement and applying ultrasonic vibrations and mechanical pressure to the reinforcement member so as to cause the latter to become embedded in the plastics material.
The reinforcement member may be applied across a joint previously formed by ultrasonic welding or otherwise, or it may be applied to an unjointed region where reinforcement is required. However, the reinforcement member may additionally serve to establish a joint between two abutting pieces of plastics material by being embedded in both pieces of material, preferably simultaneously, but alternatively sequentially.
Additionally, the reinforcement member may also be designed to serve a further purpose, for example it may carry, or be formed integrally with, one part of a two-part fastening so as to enable the plastics material to which it is secured to be fastened to some other member by means of the two-part fastening. In this case, reinforcement is normally desirable at the site of such a fastening, and in accordance with this aspect of the invention the fastening element is attached to the plastics mate rival, together with an integral reinforcement member.
The advantage of employing an ultrasonic technique is that there is effectively no risk of overheating the plastics material as in a case where the reinforcement member itself is heated and applied to a thermoplastic material. It will be appreciated that if a pre-heated reinforcement member is to be applied to a thermoplastics material, the temperature of the reinforcement member must be very carefully controlled to avoid damage to that material. In practice, it is likely that the temperature of such a pre-heated reinforcement member will be dependent on the length of time for which it is exposed to a source of heat. If it is heated too long, the temperature will then be possibly high enough to damage the thermoplastic material, or if is is heated not long enough, the temperature may not be sufficient for it to be securely ambedded in the thermoplastic material.In addition, consideration must be given to the thermal capacity of the thermal reinforcement member. Lightweight elements of low thermal capacity may have to be heated to an unacceptably high temperature if they are to carry sufficient thermal energy to enable the embedding operation to be performed. Whilst this drawback would be overcome by applying heat, or additional heat, to the reinforcement member after it is applied to the thermoplastics material, there is again a necessity for very accurate control in order to avoid damage to the thermoplastic material.
However, by contrast, in accordance with the present invention the application of ultrasonic techniques largely overcomes these drawbacks. The only limitation on the material of which the reinforcement member is made is that it must be capable of transmitting ultrasonic vibrations from a suitable transducer into the plastic material into which it is to be embedded. Thus, it effectively requires to be more rigid that the material in which it is to be embedded, and if it is to serve as a reinforcement, this is a desirable property.
Thus, in accordance with the invention the reinforcement member may be made of a suitable metal member, such as a perforated metal sheet, woven wire mesh. or the like, or it may be formed of suitable plastics material, for example in the form of a moulded grid.
To carry out the method in accordance with the invention it is only necessarg to lay the reinforcement member on the plastic material at the site where the reinforcement is required, and then apply directly to the reinforcement member the end face of the output element of a suitable ultrasonic transducer, the shape and size of the end face preferably being generally in correspondence with the shape and size of the reinforcement member so as to apply ultrsonic energy uniformly thereto over substantially the whole of its area. The ultrasonic energy intrn- duced into the plastics material in this way causes it to soften so that the application of mechanical pressure to the reinforcement member embeds it into the plastics material.
As mentioned previously, the reinforcement member may comprise a substantially flat perforated sheet of metal or suitable plastics material which is applied to a flat body of plastics material which is to be reinforced. Such body may for example comprise a generally flat tray-like structure which requires reinforcement to give it additional rigidity or load bearing capacity. Alternatively, the plastics body may comprise two members joined together in abutting or overlapping relation by ultrasonic or other means, and the reinforcement member may be applied along the length of the joint so as to provide local reinforcement at the site of the joint. In a further possibility, the reinforcement member may be utilised to join two adjacent plastic members together, with our without simultaneous welding of the abutting edges of the plastic members.
The reinforcement member may be a simple rectangular plate-like form, or it may comprise an elongated strip. Alternatively, the reinforcement member may be in the form of a circular disc. If desired, in eithr case, the reinforcement member may itself be shaped so as to imrpvoe its rigidity, for example by being formed or provided with one or more strengthening ribs which extend generally perpendicularly from the plate-like part which is actually to be embedded in the plastics material.
Additionally, the reinforcement member may carry one or more studs or other similar members which may, for example, form part of a fastening device to enable the body to which the reinforcement is attached to be releasably or otherwise secured to some other component. In a further particular example, the reinforcement member could take the form of a round disc or rectangular plate having one or more eyelets therein, so that the eyelets are secured to the plastics material and the latter is simultaneously reinforced. It will be understood that the plastics material may or may not itself be apertured at the site of the eyelets before the reinforcement member is applied.
Additionally, the reinforcement member could be of non-planar form where appropriate, e.g. curved for reinforcement of a plastics member of cylindrical shape, or of angle shape for use at a corner.
Moreover, the plastics material to which the reinforcement is applied could form part of a laminated or other composite material including a non-plastic component.
The invention will now be described by way of example with reference to the accompany drawings wherein Figure 1 shows a shallow tray of plastics material which is centrally reinforced; Figure 2 shows a joint in a length of shallow plastics trough formed from two or more pieces; Figure 3 shows a stud secured to one corner of a rectangular panel member; Figure 4 shows a semi-cylindrical component which is reinforced longitudinally; Figure 5 shows part of an angle section member which is reinforced internally; Figure 6shows part of a longitudinal strip provided with a reinforcement member; and Figure 7 shows one corner of a flexible plastic sheet provided with a reinforced eyelet.
Referring to the accompanying drawings, Figure 1 shows a shallow rectangulartray 10, the base 11 of which has been reinforced by means of a rectangular grid 12 embedded in the plastics material from which the tray is formed so that the base is thereby reinforced and its load bearing capacity is increased.
In Figure 2, a similar rectangular mesh 15 is shown joinging together two shallow channel sections 13 and 14 mde of platics material. In this case, the ends of the sections 13 and 14 are presented in abutting relation, and the two sectjions are secured in such relation by means of the grid 15. Additionally, the abutting edges of the sections 13 and 14 may be directly secured together by any suitable means such as ultrasonic welding.
In Figure 3, a stud 18 is shown secured to one corner of a composite panel 16 having a facing layer oftheremo-plastic material 17. The stud 18 includes an integral disc-like flange 19 which is formed with a plurality of apertures and is imbedded in the plastics facing layer of the panel 16.
In Figure 4 a semi-cylindrical plastics component 20 is reinforced by means of a curved piece of wire mesh 21 embedded therein where required.
In Figure 5, an angle section member 22 is internally reinforced by means of a piece of mesh 23 formed to angle shape. The angle section member 22 may be formed from two flat strips joined together in mutually perpendicular relation by menas of the mesh 23.
Figure 6 shows an elongated strip 24 of plastics material which is reinforced at a point intermediate its ends by a specially shaped piece of wire mesh 25.
This includes a central longitudinal web 26 which extends perpendicularly from the adjacent parts which are embedded in the trip 24 so as to provide additional longitudinal reinforcement against bending.
Finally, Figure 7 shows a sheet of plastics material 27 which is provided with an eyelet 28 comprising a metal ring 29 in the centre of a disc 30 of wire mesh which is ermbedded in the sheet 27.
In all the above illustrated embodiments, the reinforcementijoining members are embedded in the plastics material by placing each member in the desired position and then engaging same with the operative end face of an appropriately shaped output element of a suitable ultrasonic transducer, the size and shape of the end face preferably being generally in correspondence with the size and shape of the reinforcement member so as to apply ultrasonic energy substantially uniformly thereto over the whole of its area. At the same time mechanical pressure is applied to the reinforcement member by means of said output element, whereby the reinforcement member is securely embedded into the softened plastics material.
