The brothers teamed up with Steve Chappell to create a line of pole vaulting poles made of fiberglass material. Chappell and his business partner Lane Maestretti had already been working on pole vaulting poles in Carson City, Nevada. [4] Fiberglass poles were in its infancy at the time. Together the group made the UCS Spirit vaulting pole in ...
Fiberglass (American English) or fibreglass (Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber.The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth.
It is also used to reinforce various materials, such as tent poles, pole vault poles, arrows, bows and crossbows, translucent roofing panels, automobile bodies, hockey sticks, surfboards, boat hulls, and paper honeycomb. It has been used for medical purposes in casts. Glass fiber is extensively used for making FRP tanks and vessels. [6] [26]
Fiberglass reinforced plastic grating (also known as FRP grating, glass reinforced plastic grating or fiberglass grating) is a composite material manufactured by combining a matrix of resin and fiberglass. Fiberglass grating does not corrode like steel grating and is therefore used in corrosive environments to reduce maintenance costs.

Some construction historians have mentioned the use of latillas under the vigas for carrying poles. [11] Wood cutting was an important aspect of material production. If cutting was done shorter than needed, the builders had to wait until one year later to get the same material, thus representing a problem.
Conventional 2-wire or 3-wire distribution lines have a higher power transfer capacity, but can require 7 poles per kilometre (12 poles per mile), with spans of 100 to 150 metres (110 to 160 yards). SWER's high line voltage and low current also permits the use of low-cost galvanized steel wire (historically, No. 8 fence wire). [ 9 ]
