This invention relates to fiber reinforced polymer ( FRP grating ), and more specifically, to fiber reinforced polymer composite panels for structural support systems and a method of manufacturing thereof This invention also relates to lightweight FRP composite panels composed of reinforced fibers and matrix resin, configured for infrastructure and constructed facilities such as elevated highway structures and wall and decking systems.

Fiberglass reinforced plastic (FRP) paneling is a durable wall covering. During the FRP installation process, the panels must be cut to fit on the wall. The composition of FRP panels requires the use of special carbide tipped saw blades to perform the cut. Proper safety equipment is essential to guard against flying debris, cuts and inhaling the FRP Pultruded profiles dust.Structural panels are continually needed in constructing and repairing walls, floors, decking, bridges, roofs, and the like. In the prior art, conventional construction materials, e.g., steel, concrete, and wood, are used for high performance deck and wall structures because such materials typically have a high load bearing capacity.

There are several disadvantages associated with using such conventional construction materials in structural panels. First, such structural panels have a short service life in that they degrade over time: steel panels corrode, concrete panels spall, and wood panels rot. Second, such structural panels tend to be very heavy in order to achieve the required load bearing capacity for the specific application. Third, such structural panels require a long time for creation and erection because they are typically built and installed on site.
Put on your safety glasses, particulate respirator and leather gloves.Stretch the tape measure along the FRP beam and place a mark along one edge of the FRP panel with the carpenter's pencil at the length you need to cut. Repeat the process to place a corresponding mark on the opposite edge of the FRP sheet.

To accommodate some of the disadvantages with conventional construction materials, the prior art includes fiber reinforced polymer ( FRP) composite materials made with a honeycomb core and an outer skin. In addition, panels made of conventional FRP composite materials have lineal profiles mainly reinforced with continuous fibers in the axial direction.

There are several disadvantages associated with using such conventional FRP materials in structural panels. First, although conventional FRP composite materials are lightweight, they lack the required load-bearing capacity to handle high performance deck and wall structures. Therefore, conventional FRP composite materials are used only for light duty floor systems and building panels. Second, conventional FRP ladder composite panels often develop moisture ingress and resin-dominated failure with respect to the honeycomb core and an outer skin. Third, the lineal profile and use of continuous fibers in the axial direction result in a reduced load bearing capacity.

Lay the FRP panel flat on a table that is large enough to support the entire length of the FRP panel.Snap a line between the two pencil marks with the chalk line.Secure the carbide circular saw blade to the circular saw.Pull the marked line over the edge of the table.Align the carbide circular saw blade with the chalk line that you snapped in the previous step, depress the trigger of the circular saw and slowly push the blade into the FRP panel.

Therefore, there is a need for a FRP composite panel that is lightweight, yet has a high load rating due to high strength to weight ratio. There is a further need for a FRP composite panel that has a long service life due to its resistance to corrosion. There is still a further need for a FRP grating composite panel that is easy and quick to erect and become operational.

There is also a need for a FRP composite deck system that is lightweight, yet can withstand the heavy loads associated with highway bridges and decking systems. The FRP composite deck systems must also have a long service life and be prefabricated to allow for easy and quick installation. Slowly push the carbide blade across the FRP panel, while keeping the blade aligned with the chalk line.Place the sharp edge of the utility against the cut edge of the FRP, tilt the blade on a 15-degree angle and drag the knife along the cut to remove any burr remaining from the cutting process. Do not push the blade along the cut--this will damage the FRP panel.
