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 of making a reinforced resin hose connector plug, comprising:
providing a die having a cylindrical body terminating in a first and second rounded end at opposite ends of the cylindrical body;
winding a fibrous material around the die including the first and second rounded ends while the fibrous material is tensioned, wherein the fibrous material is placed to extend in a continuous manner a multiplicity of times across a width of the rounded ends 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.

2. The method of claim 1 , wherein the die further comprises a pole connected to the cylindrical body, wherein the pole extends perpendicular to a longitudinal axis of the cylindrical body.

3. The method of claim 2 , wherein removing the plug includes cutting the cured fiber-reinforced resin plug around a circumference of the die on both sides of the pole to produce two reinforced resin plugs.

4. The method of claim 1 , wherein the fibrous material is applied before the curable resin.

5. The method of claim 1 , wherein the curable resin is applied before the fibrous material.

6. The method of claim 1 , wherein the curable resin and the fibrous material are applied together.

7. The method of claim 1 , wherein the fibrous material comprises spun filaments.

8. The method of claim 1 , wherein the fibrous material comprises a continuous filament.

9. The method of claim 1 , wherein the fibrous material is a mesh of interconnected filaments.

10. The method of claim 1 , wherein the curable resin is an elastomer.
