Abstract
The present disclosure relates to a pole shield for extending around a pole structure. The pole shield comprises a sheet of composite material forming a hollow structure having an open first end and an opposed open second end. The sheet of composite material comprises from about 0% to about 80% by weight of a reinforcement impregnated with about 20% to about 50% of a polyurethane resin composition comprising a combination of a polyol component and a polyisocyanate component. Two or more pole shields may be stacked one on top of the other to form a pole shield structure which extends the height of protection of the pole structure. The pole shield can be used for protecting a pole structure from damage, such as from fire, rain, wind, sand, ice, pests, moisture or electrical. The pole shield may also be used to provide structural support to a pole structure.
