Composition fiber glass utility pole
First Claim
1. A hollow pultruded fiber glass utility pole comprising:
- (a) a center section comprising fiber glass oriented at an angle to a center axis, the center section comprising from 5% to 15% of a total diameter of the utility pole;
(b) a mid-section surrounding the center section, the mid-section comprising fiber glass oriented parallel to the center axis, the mid-section comprising 70% to 90% of the total diameter of the utility pole; and
(c) an outer section surrounding the mid-section, the outer section comprising fiber glass oriented at an angle to a center axis, the outer section comprising 5% to 15% of the total diameter of the utility polewherein the center, mid- and outer sections of the hollow pultruded fiber glass utility pole are pulled through a continuous pulling device.
