Abstract

A tooling to enable variation in radius of molded continuous fiber reinforced polymer curved components which includes a first tooling surface formed on a first tooling member which may be formed of sprung material, a second tooling surface formed on a second tooling member which may be formed of sprung material. The first tooling surface and the second tooling surface are positioned to lie one over the other to form a gap therebetween for receiving a supply of continuous fiber reinforced polymer. The first tooling surface and the second tooling surface are movable towards and away from each other to modify the size of the gap therebetween and thereby modify the amount of compression applied by the first and second tooling surfaces on the continuous fiber reinforced polymer positioned therebetween. A mechanism is engaged with the first tooling member to modify a curvature of the first tooling surface.

First claim

The invention claimed is:

1. A tooling to enable variation in radius of molded continuous fiber reinforced polymer curved components comprising:
a first tooling surface formed on a first tooling member,
a second tooling surface formed on a second tooling member,
the first tooling surface and the second tooling surface being positioned to lie one over the other to form a gap therebetween for receiving a supply of continuous fiber reinforced polymer,
the first tooling surface and the second tooling surface being movable towards and away from each other to modify a size of the gap therebetween and thereby modify the amount of compression applied by the first and second tooling surfaces on the continuous fiber reinforced polymer positioned therebetween, and
a mechanism engaged with the first tooling member to modify a curvature of the first tooling surface,
wherein the mechanism comprises a first pin extending through the first member located along a length of the first member and a second pin extending through the first member located along the length, spaced from the first pin, wherein the second pin is movable towards and away from the first pin to cause a greater or lesser degrees of bending of the first member and first tooling surface dependent upon movement of the second pin towards and away from the first pin.

2. The tooling according to claim 1 , wherein the mechanism further comprises a first pin extending through the second member located along a length of the second member and a second pin extending through the second member located along the length, spaced from the first pin, wherein the second pin is movable towards and away from the first pin to cause a greater or lesser degrees of bending of the second member and second tooling surface dependent upon movement of the second pin towards and away from the first pin.

3. The tooling according to claim 1 , wherein the first tooling member is formed of sprung material.

4. The tooling according to claim 1 , wherein the second tooling member is formed of sprung material.

5. A tooling to enable variation in radius of molded continuous fiber reinforced polymer curved components comprising:
a first tooling surface formed on a first tooling member, the first tooling member having a first pin therethrough located along a length of the member and a second pin therethrough located along the length, spaced from the first pin,
a second tooling surface formed on a second tooling member, the second tooling member having a first pin therethrough located along a length of the member and a second pin therethrough located along the length, spaced from the first pin,
the first tooling surface and the second tooling surface being positioned to lie one over the other to form a gap therebetween for receiving a supply of continuous fiber reinforced polymer,
the first tooling surface and the second tooling surface being movable towards and away from each other to modify a size of the gap therebetween and thereby modify an amount of compression applied by the first and second tooling surfaces on the continuous fiber reinforced polymer positioned therebetween,
the second pin of each tooling surface being movable towards and away from the first pin of each tooling surface to cause a greater or lesser degree of bending of each of the tooling members and tooling surfaces dependent upon the movement of the second pins towards and away from the first pins.

6. The tooling according to claim 5 , wherein the first pin of the first tooling member and the first pin of the second tooling member are fixed in place and not movable.

7. The tooling according to claim 5 , wherein the first pin of the first tooling member and the first pin of the second tooling member are movable towards and away from the second pin of the first tooling member and the second tooling member, respectively.

8. The tooling according to claim 5 , wherein the first tooling member is formed of sprung material.

9. The tooling according to claim 5 , wherein the second tooling member is formed of sprung material.
