Abstract
A system and method of a structural panel includes a first outer sheet and a second outer sheet, the first outer sheet and second outer sheet including a polygon shape; a core arrangement sandwiched between the first outer sheet and the second outer sheet, the core arrangement comprising two or more discrete members arranged adjacent each other, the discrete members shaped or structured to reduce crack initiation and propagation within the core arrangement.
Claims23
A structural panel comprising;
- a first outer sheet and a second outer sheet, the first outer sheet and second outer sheet comprise a polygon shape,
- a core arrangement sandwiched between the first outer sheet and the second outer sheet,
- the core arrangement comprising a plurality of rigid cylindrical tubes arranged adjacent each other, wherein the plurality of rigid cylindrical tubes are discrete members separated from each other;
- and
- a plurality of adhesive spots applied along the discrete members, between the adjacent discrete members, and between the discrete members and the first and second outer sheets so as to connect the plurality of rigid cylindrical tubes, the first outer sheet and the second outer sheet to form the structural panel, and wherein the plurality of adhesive spots are evenly spaced apart;
- wherein the plurality of adhesive spots are further arranged to separate each of the plurality of rigid cylindrical tubes from an adjacent cylindrical tube, the first outer sheet and the second outer sheet so as to reduce crack initiation and continuous propagation of the crack within the core arrangement.
