Repair of Wood Piles Using Prefabricated Fiber-Reinforced Polymer Composite Shells Roberto Lopez-Anido, M.ASCE1; Antonis P. Michael, S.M.ASCE2; Thomas C. Sandford, M.ASCE3; and Barry Goodell4 Abstract: An effective method for combined environmental protection and structural restoration of wood piles in waterfront facilities is not available.
FRP vs Wood When it comes to structural applications, Bedford’s fiberglass reinforced plastic offers significant advantages compared to timber. Unlike wood, our fiberglass shapes won’t warp, rot or decay from exposure to moisture.
Non-wood fiber segment accounted for the largest market in global natural fiber reinforced composites market. Non-wood fibers include grass fibers, leaf fibers, bast fibers, fruit fibers, and st fibers.

Three-dimensional fiberglass-reinforced polymer composites are materials with three-dimensional fiber structures that incorporate fibers in the x-direction, y-direction and z-direction. The development of three-dimensional orientations arose from industry's need to reduce fabrication costs, to increase through-thickness mechanical properties, and to improve impact damage tolerance; all were problems associated with two-dimensional fibre-reinforced polymers.
Fiber reinforced plastics are a composite material consisting of a matrix, usually a thermoset resin, and a reinforcement of fibers. Thermoset polymers used as resins in the manufacture of FRP include polyurethane, polyester, vinyl ester, epoxy, and occasionally phenol formaldehyde.
Italian extrusion machinery maker ICMA San Giorgio (San Giorgio su Legnano, Italy) was an early developer of wood-reinforced polymer products, with partner G.O.R. Applicazioni Speciali SpA. Their 1974 Woodstock process mixed polypropylene (PP) flakes with wood flour to make sheet material for auto interiors, still used today by several licensees.
Six wood-fiber-reinforced polymer (FRP) composite projects have been conducted over the past decade with three types of technologies developed at the University of Maine.
Fiber Reinforced Polymers (FRPs) have been used for seismic retrofit applications in masonry and concrete structures for many years. FRP has also been used for general restoration purposes in wood structures.
Wood plastic composite with high modulus and impact strength were manufactured by combining polyethylene (PE) or polypropylene (PP) with wood fiber (WF) using twin-screw extruder techniques. The advantage of using low melt viscosity polymer matrices is that it enhances the modulus and reduces the overall viscosity of the system.
fiber and carbon fiber, as wood fiber is a natural material and therefore its microstructure contains a lot of vessels (used for transportation of water and nitrite during the growth of the plant).
Wood flour/fiber reinforced polymer composites are commonly known as wood–plastic composite (WPC). It is composed of wood fibers from recovered sawdust (and other cellulose-based fiber fillers such as peanut hulls, bamboo, st, digestate, etc.) and waste plastics including high density polyethylene (HDPE) and polyvinyl chloride (PVC).
