1. A fiber-reinforced plastic (FRP) panel comprising:
an inner core material having a perimeter and forming at least one core channel that extends around the perimeter and inward a predetermined depth from the perimeter toward a center of the FRP panel;
a first outer wall coupled to a first side of the inner core material;
a second outer wall coupled to a second side of the inner core material opposite the first outer wall;
at least one elastic member received within the at least one core channel; and
a frame disposed between the inner core material and the at least one elastic member,
wherein an interior surface of the frame is configured to be received within the at least one core channel and an exterior surface of the frame forms at least one frame channel configured to receive the at least one elastic member,
wherein the frame comprises a first outer edge that extends between the first outer wall and the inner core material and a second outer edge that extends between the second outer wall and the inner core material to seal the perimeter of the inner core material,
wherein the at least one elastic member forms a recess extending along a top surface of the elastic member and extends inwardly from the top surface of the at least one elastic member toward a bottom surface of the at least one frame channel until contacting the bottom surface of the at least one frame channel,
wherein the recess of the at least one elastic member is configured to receive a joining member for joining to another FRP panel.
