There is a need for a FRP composite panel
This invention relates to fiber reinforced polymer ( FRP), and more specifically, to lightweight fiber reinforced polymer composite decks for structural support systems and to a method of manufacturing said FRP grating . The lightweight FRP composite decks are composed of reinforced fibers and matrix resin, configured for infrastructure and constructed facilities such as elevated highway structures and wall and decking systems.
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 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.
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 composite panel that is easy and quick to erect and become operational.
There is also a need for a FRP manufacturer 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.
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 dust.
Stretch the tape measure along the FRP sheet 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 beam .
The present invention solves the problems associated with conventional structural panels by providing a fiber reinforced polymer ( FRP) composite panel. A FRP composite panel comprises a plurality of components, joined through a shear key system that provides an extensive bonding surface and a mechanical interlock. Each component is further comprised of a plurality of cells, each cell having four or more sides wherein at least two adjacent sides intersect at an obtuse angle, offset from ninety (90) degrees.
The fiber architecture of the components comprises multiple layers of multi-axial stitched fabrics, unidirectional rovings, woven cloth, and mats used as reinforcements. The fiber architecture develops fiber continuity between the cell components and provides adequate fiber reinforcement along main stress paths.
The cross sectional cellular shape and fiber architecture of the FRP ladder of the present invention provide distinct advantages over the prior art. First, the FRP composite panels of the present invention provide a lightweight, strong and durable structure that will not corrode like steel, spall like concrete, or rot like wood. Therefore, the panels of the present invention have a long service life and a reduced maintenance cost due to these fatigue and corrosion resistant properties.
Lay the FRP panel flat on a table that is large enough to support the entire length of the FRP panel.
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.
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 .
Second, the FRP composite panels of the present invention have enhanced load bearing and interlocking capacity as compared to conventional FRP floor systems and building panes. The high load ratings are due to the high strength to weight ratio of the panels, resulting in a panel of the present invention having 3 to 4 times the load capacity of a reinforced concrete deck with only twenty percent (20%) of the weight. Further, stiffness of an FRP composite panel in the direction perpendicular to traffic is adequate to provide the transverse load distribution to supporting beams.
Third, the fiber architecture of the present invention is reinforced with heavy multi-axial stitched fabrics, continuous rovings woven cloth and mats resulting in superior mechanical properties as compared to existing FRP composite lineal profiles. In addition, the composite fiber architecture overcomes the problems associated to moisture ingress and resin-dominated failure observed in panels with honeycomb core and outer skins.
