Abstract

A method includes providing a die having a cylindrical body terminating in a rounded end, wrapping a fibrous material around the die while the fibrous material is tensioned, wherein the fibrous material is placed to extend in a continuous manner across the width of the rounded end of the body and to opposite sides of the cylindrical body, applying a curable resin on the die, curing the resin, and removing a reinforced cured resin plug from the die.

First claim

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. A method for closing a barbed conduit connector termination of a vehicle, comprising:
placing a plug made from a reinforced resin on a barbed conduit connector termination on a vehicle, wherein the plug comprises a hollow cylindrical body and a rounded end portion having a curvature in the radial direction, wherein the hollow cylindrical body is closed by the rounded end portion on one end, and the cylindrical body has an open opposite end, wherein the hollow cylindrical body and rounded end portion are continuously joined, wherein the plug comprises tensioned fibrous material that extends in a continuous manner from one side of the cylindrical body in a lengthwise manner along the body, then across the width of the rounded end, and then to an opposite side of the cylindrical body in a lengthwise manner along the body;
placing the open end over the barbed conduit connector termination, wherein the hollow cylindrical body fits juxtaposed outside on the barbed conduit connector termination; and
placing a clamp on the plug that compresses the cylindrical body to the barbed conduit connector termination.

2. The method of claim 1 , wherein a pressure inside the barbed conduit connector termination applies a force on an inside surface of the rounded end, and the force is transferred via the fibrous material to a body portion being compressed by the clamp.

3. The method of claim 1 , wherein the barbed conduit connector termination is a hose barb.

4. The method of claim 1 , wherein a pressure inside the plug is 50 psig or more.

5. The method of claim 1 , wherein the fibrous material comprises a plurality of discrete filaments, at least one or more extending in a continuous manner across the width of the rounded end and to the sides of the body.

6. The method of claim 1 , wherein the fibrous material comprises a mesh.

7. The method of claim 1 , wherein the plug comprises more than one layer, each layer having tensioned fibrous material and resin.

8. The method of claim 1 , wherein the plug comprises at least one layer having a cured resin, and further comprises the fibrous material within the resin.

9. The method of claim 1 , wherein the plug is made from an elastomer.

10. The method of claim 9 , wherein the elastomer is silicone rubber, butyl rubber, ethylene propylene rubber, ethylene propylene diene rubber, polyisoprene rubber, polybutadiene rubber, or nitrile rubber.
