Portable panel construction and method for making the same
View Patent ↗Disclosed herein is a portable panel having numerous favorable characteristics. The panel comprises a core having a length, a width, a first side and a second side. A first fiber layer is attached to the first side while a second fiber layer is attached to the second side. A first polyurethane layer is impregnated in the first fiber layer while a second polyurethane layer is impregnated into the second fiber layer. A first skin is attached to the first polyurethane layer while a second skin is attached to the second polyurethane layer. The panel can be used in the manufacture of tables, flooring, risers, stages, bleachers, and the like.
1. A method of constructing a panel comprising:
a) providing a frame;
b) placing a core within the frame;
c) attaching a first fiber layer to a first side of the core and a first side of the frame;
d) attaching a second fiber layer to a second side of the core and a second side of the frame;
e) impregnating a first polyurethane layer in the first fiber layer;
f) attaching a first skin to the first polyurethane layer and the frame, the first skin and frame constraining the first polyurethane layer as it cures;
g) impregnating a second polyurethane layer in the second fiber layer; and
h) attaching a second skin to the second polyurethane layer and the frame, the second skin and frame constraining the second polyurethane layer as it cures.
2. The method of claim 1 , wherein the frame forms the perimeter of the panel.
3. The method of claim 1 , wherein the method is performed without a mold.
4. A method of constructing a panel comprising:
a) providing a frame having an open bottom and an open top;
b) placing a core within the frame to expose the core through the open bottom and the open top;
c) attaching a first fiber layer to a first side of the core and a first side of the frame;
d) attaching a second fiber layer to a second side of the core and a second side of the frame;
e) impregnating a first polyurethane layer in the first fiber layer;
f) attaching a first skin to the first polyurethane layer and the frame, the first skin and frame constraining the first polyurethane layer as it cures;
g) impregnating a second polyurethane layer in the second fiber layer;
h) attaching a second skin to the second polyurethane layer and the frame, the second skin and frame constraining the second polyurethane layer as it cures; and
i) integrating the frame with the core and layers by performing steps e)-h).
5. The method of claim 1 , wherein the frame forms the perimeter of the panel.
6. The method of claim 1 , wherein the method is performed without a mold.
