Abstract
The invention provides a process for producing a component of a plastics material which is strengthened and reinforced by a resin-impregnated fibrous material which adheres to a surface thereof. The surface of the component is contacted with a fibrous material impregnated with a resin in a settable state, and setting of the resin is effected, while the fibrous material is caused to ahere to the surface of the component. The plastics material is a polyolefin material, and the surface is subjected to activation thereof prior to the contacting.
Claims
1 . In the production of a component of a plastics material which is strengthened and reinforced by a resin-impregnated fibrous material which adheres to a surface thereof, by contacting said surface of the component with a fibrous material impregnated with a resin in a settable state, and effecting setting of the resin while causing the fibrous material to adhere to said surface of the component, the process which comprises using as the plastics material a polyolefin material and which includes the step, prior to the contacting, of subjecting said surface of the component to activation thereof, the activation being by surface fluorination by exposing the surface to be fluorinated to a fluorine-containing gas at a pressure of 1 - 500 KPa, at a temperature above 0°C and below the melting point of the material of the component.
2. A process as claimed in claim 1 , in which the polyethylene material is selected from polyethylenes, polypropylenes, copolymers of ethylene and propylene and blends of such polyolefins.
3. A process as claimed in any one of the preceding claims, in which the surface activation acts to provide the surface-activated component with a surface tension at 20 °C of at least 40 mN/m.
4. A process as claimed in any one of the preceding claims, in which the fluorine-containing gas forms part of a mixture with other gases, the fluorine- containing gas forming 1 -30% by volume of said mixture and the temperature being 20-100°C.
5. A process as claimed in claim 4, in which the gas mixture comprises 5 - 20% by volume of the fluorine-containing gas and 5 - 95% by volume of oxygen, so that the surface fluorination is a surface oxyfluorination. 53
A process as claimed in claim 5, in which, after said oxyfluorination, the surface is subjected to hydrolysis.
7. A process as claimed in any one of the preceding claims, in which the fibrous material is subjected to surface fluorination thereof prior to impregnation thereof with resin.
8. A process as claimed in claim 7, in which the reinforcing material has fibres which are selected from glass fibres, carbon fibres, polyester fibres, polyamide fibres, polyolefin fibres and mixtures thereof.
9. A process as claimed in any one of the preceding claims, in which the surface is subjected to degreasing prior to activation thereof.
10. A process as claimed in any one of the preceding claims, in which the surface, after activation thereof and prior to the contacting, is subjected to degreasing.
1 1 . A process as claimed in any one of claims 1 - 10 inclusive, in which causing the fibrous material to adhere to the surface of the component is by means of a resin which is different from the resin which impregnates the fibrous material, each resin being selected from epoxy resins and polyester resins
1 2. A process as claimed in any one of claims 1 - 1 1 inclusive, in which causing the fibrous material to adhere to the surface of the component is by means of a resin which is the same as the resin which impregnates the fibrous material, each resin being selected from epoxy resins and polyester resins.
1 3. A component of a plastics material which is strengthened and reinforced by a resin-impregnated fibrous material which adheres to a surface thereof, whenever produced in accordance with the process of any one of claims 1 - 12.
