What is FRP Rebar?
FRP Rebar is produced through the process of pultrusion in which several thousand glass filaments are saturated with resin and pulled through a gauge die, then helical wrapped creating a slight bar deformation and cured under tension along several graduated temperature zones until cure is complete.
Resin matrix used for rebar should be VinylEster/Epoxy: A strong, thermal-set resin matrix with a stiff vinyl epoxy "backbone". Vinyl-Ester is a highly durable system, recommended for excellent structural integrity & high alkali resistant properties. Polyester Resin is a less expensive resin matrix that is less durable & has weaker chemical resistance. Polyester matrix rebar is sometimes used in applications that are less critical for corrosion protection & strength, often for temporary structures or solely for Non-Conductive & Non-Magnetic properties.
**Kodiak FRP Rebar can be ordered with silicate impregnation for superior pullout resistance. Kodiak's coated GFRP & BFRP rebar has helical ribs as well as hard silicate impregnation formed in process instead of a cured bar that's then coated as a secondary process like some others on the market.
American History of FRP Rebar
Kodiak FRP Rebar is the first FRP rebar made in the USA, from which Testing & application standards as used in ACI440 were set. The Mckinleyville Bride of Buffalo Creel was first vehicular bridge in the U.S. using only GFRP concrete reinforcement (WV Mckinleyville bridge 1996) for the U.S. Federal Highway Department with The University Of West Virginia's Dr. Hota GangaRao
FRP Rebar is the "Hybrid" concrete reinforcement noted for its high tensile strength, light weight , Non-Corrosive, & Non-Conductive properties. KODIAK GFRP rebar was the first structurally viable FRP rebar developed & produced in the United States. 1982, Leroy applied his extensive knowledge in structural plastics & years of experience in the field of plastics pultrusion moved with the idea of industry change for infrastructure sustainability. 1984, Leroy Heston stepped forth with Kodiak Fiberglass Rebar, as the most effective solution to the US’s crumbling bridge infrastructure. Over time, chloride salts used to de-ice bridges slowly penetrate bridge concrete to its steel reinforcement. When chlorides chemically react to steel rebar, rust is formed expanding as it reacts. The expansion of rust exerts tremendous internal pressure from the inside of the concrete structure eventually causing the concrete to crack, ultimately causing structural failure shortening the working life of the structure

Responsible Building with Kodiak FRP Rebar – Sustainable Infrastructure for the Future of America
Use of advanced materials in design is the key to building green...Sustainable Building!
There is not a legitimate argument in the facts. Infrastructure development using Kodiak FRP rebar is the most economical option. Anything less is recklessly short sighted cost analysis projection. Ignoring service life cost projections is a display of defiance to fiscal logic, an adolescent mentality that we just cant afford as a society in progress. Kodiak GFRP reinforcement cost is fractionally higher on front end budget calculation. Analyzation of cost to service life savings when accounted, convert to an astronomical fiscal return on program investment.
Too often, critical working life cost analysis is dismissed or minimized carelessly with short sighted budget politics over-ruling or ignoring the best interests of the peoples national infrastructure longevity & sustainability. Save a buck today & kick the can, spend 5 times as much next time to demolish & rebuilt again, ...and Again.
Now is the time for responsible planning. Its time to scrutinize service life projections critical to long term value engineering with use of high quality, efficient materials for the infrastructure of our country, our home.
The Carbon footprint of steel in production is much higher than that of FRP rebar production, even without consideration of the footprint left by demolition & rehabilitation time & time again. Not to mention the carbon offset provided in the ability to use less concrete in the initial structure by a thoroughly strategized engineering design.
