supplier– Applicator and
Architectural Finishes
Who is Composites Advantage, LLC ?
FRP is a strengthening tool
Conventional strengthening tools– Concrete enlargement (shotcrete),
underpinning, post tensioning, steel platesFiber-reinforced polymers (FRP)
– A composite system (carbon/glass fabric + epoxy matrix) used to augment another composite system (concrete + rebar)
Formats: “wrap”, prefab: dowel bars, plates, strips
FRP provides on the outside what concrete is missing inside (e.g. hoop steel for columns).
Strengthening applications
Change of use…increased live/wheel loads– Installation of heavy machinery– expansion of existing facilities
Construction or design defects Code changes…new design criteria
– legislature driven Seismic retrofit Blast protection Deterioration remediation
For concrete columns, beams, slabs, walls
Fiber composites
Fabric can be custom cut at project site
Easy to handle and install

Fabric ManufacturingFabric Manufacturing
Spools of fibers are combined into fabrics and pre-cured strips
Key FRP concepts
Confinement – Columns
Think of a weightlifter’s waist belt
FRP keeps column rebar from buckling
Added tensile strength– Underside of beams
Shear strength– Walls
Adds in and out-of-plane strength
From military to construction
History of FRP for construction
Mid 1980s– EU and Japan begin FRP research and development
Late 80s, early 90s– Funding for US universities begins
Leverage technology developed during the Cold War FHWA, CalTrans*, DARPA UCSD, UofM/Rolla, Penn State, Brown University, North
Carolina State, University of Arizona

FRP’s benefits Engineering benefits
– Very high tensile strength (10-14x steel) but also ductile (complements concrete’s properties)
– Very corrosion resistant Architectural and construction benefits
– Easier to apply/install– Lightweight, thin, unnoticeable – Minimal structure/tenant intrusion & disruption
Economic benefits – Low installation costs – Great, tangible, ROI FRP works.
It’s been reviewed, validated, approved, documented and
incorporated worldwide.
Building owner benefits
Shorter projects
Lower cost
Safe and effective
Much less tenant disruption
Industry/Agency/Peer acceptance
Installation expertise
Proper usage (structural engineering) Safety & insurance (look for qualified contractors) Installation environment (doing your homework) Demolition Surface preparation Proper installation techniques
– Keen attention to detail QA/QC (core competence)
– Samples collection and mgt. Finishing (virtually any finish can be applied)
FRP benefit: ROICase Study
$18.5M D/B Renovation Project: “BEQ-26”
• San Diego based Navy barracks underwent renovation, including seismic.
• Original plan called for shotcrete for strengthening.• Through collaborative efforts, FRP was VE’d in its place• Navy benefits:
• 60% less demolition (landfill)• 50% less disruption• no loss of square footage space• Navy saved $500,000 and 9months (roughly a 36 mo prjt)
• Project was 1 of 21 nominees for the 2002 Charles Pankow Award for Innovation
Next steps
Composites Advantage, LLC. can meet with you or your SE/architect to discuss FRP’s benefits in more detail– VE analysis– Free consultation
Information is available in CD or print formFor projects already spec’d or on the street,
we are ready to do the work
