Abstract

The present invention relates to a process for the production of reinforced plastics components. The process includes a) provision of at least one reinforcing material in a cavity of a molding device, b) provision of at least one starting material in a container, c) insertion of the container into the molding device, d) introduction of the at least one starting material from the container into the cavity, wherein the at least one starting material penetrates at least to some extent through the at least one reinforcing material, e) hardening of the at least one starting material with the at least one reinforcing material to give a reinforced plastics component, and f) demolding of the reinforced plastics component. The invention further relates to a device and to an assembly for the production of reinforced plastics components.

First claim

The invention claimed is:

1. A process for the production of reinforced plastics components, comprising the following steps:
a) providing at least one reinforcing material in a cavity of a molding device,
b) providing at least one starting material in a container, wherein the at least one starting material is both stored and transported in the container,
c) inserting the container into the molding device,
d) introducing the at least one starting material from the container directly into the cavity, wherein the at least one starting material passes through a mixing unit, wherein the at least one starting material penetrates at least to some extent through the at least one reinforcing material provided in the cavity,
e) hardening of the at least one starting material with the at least one reinforcing material to give a reinforced plastics component, and
f) demolding of the reinforced plastics component;
wherein the at least one reinforcing material has a surface modification that is chemically and/or physically adapted to the at least one starting material.

2. The process according to claim 1 wherein, in step b), at least one first starting material is provided in a first container and one second starting material is provided in a second container.

3. The process according to claim 2 wherein, before step d), at least the first starting material from the first container, or from a first chamber of the container, and the second starting material from the second container, or from a second chamber of the container, are mixed with one another in a mixing unit.

4. The process according to claim 1 , wherein the volume of the at least one starting material corresponds to the unoccupied volume of the cavity of the molding device.

5. The process according to claim 1 wherein, before step c), in step d), or before step e), the at least one starting material is one of thermally activated, chemically activated, and mechanically activated.

6. The process according to claim 1 , wherein the at least one starting material additionally comprises at least one of an activator and a catalyst.

7. The process according to claim 2 , wherein the first starting material in the first container additionally comprises an activator.

8. The process according to claim 1 wherein, in step c), at least one of at least one activator and at least one catalyst is added to the at least one starting material.

9. The process according to claim 1 , wherein the introducing in step d) is achieved by a piston, by reduced pressure in the cavity, or by a squeeze roll which acts on the at least one starting material in the container.

10. The process according to claim 1 , wherein the container is selected from the group consisting of tubular bag, double-chamber bag, cartridge, capsule, drum, beaker, cylinder, vessel, pad and combinations thereof.

11. The process according to claim 1 , wherein the at least one starting material provided in step b) comprises caprolactam.

12. A device for the production of reinforced plastics components, comprising:
at least one cavity of a molding device to receive a reinforcing material,
a reception device to receive at least one container for at least one starting material, wherein the container is configured for storage, transport and introduction of the at least one starting material into the cavity,
a delivery device for the delivery of the at least one starting material from the container directly into the cavity, and
for the at least one starting material, a mixing unit arranged between the reception device and the cavity, wherein the mixing unit is integrated into the at least one container.

13. The device according to claim 12 , wherein the reception device comprises at least one device for the activation of the at least one starting material in the at least one container.

14. The device according to claim 12 , comprising at least one first cavity and one second cavity of the molding device wherein the volume of the at least one first cavity differs from that of the at least one second cavity.

15. An assembly for the production of reinforced plastics components, comprising:
i) at least one reinforcing material in a cavity of a molding device,
ii) at least one starting material in at least one container, wherein the container is configured for storage, transport, and introduction of the at least one starting material from the container directly into the cavity, and
iii) at least one of at least one activator effective for the at least one starting material, and at least one catalyst effective for the at least one starting material,
wherein the at least one reinforcing material has a surface modification that is at least one of chemically appropriate and physically appropriate for the at least one starting material.

16. The process according to claim 2 , wherein the second starting material in the second container additionally comprises a catalyst.
