Laminated wood products

A layered sheet-like product comprising:

• two sheets of wood, each having grooves on one surface and flexible means bonded between said sheets on the surface of said sheets opposite said grooves, said grooves and said flexible means forming hinge-like connections at said grooves, said sheets and said flexible means adhered together, said wood sheets being compressed around said flexible means to lock said flexible means in place and form a unitary product.

A corrugated wood structure comprising:

• a core and at least one facing skin adhered to said core, said core including at least two sheets of wood bearing parallel grooves on each said sheet at predetermined registering locations for facilitating bending of said sheet and flexible means bonded between said sheets opposite said grooves, said grooves and said flexible means forming hinge-like connections at said grooves, said core being formed by bending said sheet along said grooves into a series of consecutively inverted equilateral triangular shaped sections, each of said sections having an apex in which grooves from two adjacent triangles meet.

A honeycomb structure comprising:

• (a) a core comprised of a plurality of strip-like members, said members being comprised of two strips of wood having a flexible layer bonded therebetween, said flexible layer having a form such that said two strips may be adhered, directly one to the other around portions of the flexible layer, with said flexible material therebetween, said strips including a plurality of grooves substantially perpendicular to their longitudinal direction for facilitating bending at said grooves, said strip-like members being bent to form alternate high and low surfaces, adjacent bent strip-like members being adhered to one another at said grooves forming an array of cells;
• and
• (b) at least one facing adhered to one side of said array.
