Abstract
A board material A board material having a flexible sheet member, and a plurality of hard strip members including a plurality of first hard strip members bonded in parallel to a first side of the flexible sheet member and second hard strip members arranged into sets and bonded in parallel to a second side of the flexible sheet members corresponding to the first hard strip members, the first hard strip members having a width in an integral multiple of the width of the second hard strip members.
Claims10
A board material comprising:
- a flexible sheet member, said flexible sheet member having a first surface and a second surface opposite to said first surface;
- and
- a plurality of hard strip members, said hard strip members including a plurality of first hard strip members bonded in parallel to the first surface of said flexible sheet member, said first hard strip members each have two bevelled end edges, and a plurality of second hard strip members arranged into sets and bonded in parallel to the second surface of said flexible sheet member corresponding to said first hard strip members, said second hard strip members each having two bevelled end edges, said first hard strip members having a width in an integral multiple of the width of said second hard strip members.
A board material comprising:
- a plurality of flexible sheet members an arranged in parallel and spaced from one another at a pitch, said flexible sheet members each having a first surface and a second surface opposite to said first surface;
- and
- a plurality of hard strip members, said hard strip members each having two bevelled end edges, said hard strip members including a plurality of long hard strip members and short hard strip members, said long hard strip members being symmetrically bonded in parallel to the first and second surfaces of said flexible sheet members, said short hard strip members being arranged in set and symmetrically bonded to the first and second surfaces of said flexible sheet members and aligned in line between each two adjacent long hard strip members, said long hard strip members having a length equal to the combined widths of said flexible sheet member plus the gap between each two adjacent flexible sheet members, said short hard strip members each having a width equal to the width of one of said flexible sheet members.
A board material comprising:
- a plurality of flexible cord members arranged in parallel and spaced from one another at a pitch;
- and
- a plurality of hard strip members, said hard strip members including long hard strip members and short hard strip members, said long hard strip members being arranged in pairs and symmetrically bonded to said flexible cord members at two opposite sides in a parallel manner, said short hard strip members being bonded to said flexible cord members at two opposite sides between each pair of said long hard strip members, said long hard strip members having a length equal to the combined widths of said flexible sheet member plus the gap between each two adjacent flexible sheet members, said short hard strip members each having a width equal to the width of one of said flexible sheet members.
