Abstract

A carbon fiber tubular pole and method of construction thereof. The pole includes a left in place lightweight mandrel, preferably formed of tubular polyvinylchloride or cardboard, which substantially reduces cost of manufacture. A socket is formed in the carbon fiber tubular pole for receiving an adjacent carbon fiber tubular pole.

Claims (12)

1. A carbon fiber coupling for coupling tubular poles, comprising:

a carbon fiber tubular pole having a narrow cylindrical portion and an enlarged cylindrical portion with an intermediate tapered portion located therebetween;

said carbon fiber tubular pole being formed from a tubular carbon fiber sleeve and a second sleeve disposed to tightly conform against said tubular carbon fiber sleeve;

a resin bonding said tubular carbon fiber sleeve to said second sleeve for providing a unitary carbon fiber tubular pole;

an integral socket formed by said enlarged cylindrical portion of said carbon fiber tubular pole for providing a coupling for receiving a narrow cylindrical portion of a second carbon fiber tubular pole; and

said second sleeve being a fiberglass sleeve.

2. A carbon fiber coupling for coupling tubular poles, comprising:

a carbon fiber tubular pole having a narrow cylindrical portion and an enlarged cylindrical portion with an intermediate tapered portion located therebetween;

said carbon fiber tubular pole being formed from a tubular carbon fiber sleeve and a second fiberglass sleeve disposed to tightly conform against said tubular carbon fiber sleeve;

a resin bonding said tubular carbon fiber sleeve to said second sleeve for providing a unitary carbon fiber tubular pole;

an integral socket formed by said enlarged cylindrical portion of said carbon fiber tubular pole for providing a coupling for receiving a narrow cylindrical portion of second carbon fiber tubular pole; and

said narrow cylindrical portion of said carbon fiber tubular pole being curved for providing a curved carbon fiber tubular pole connector.
