1. A method of manufacturing a multilayered material, the method comprising:
adhesively bonding a first fiber reinforced layer directly on a first surface of a foam layer; and
adhesively bonding a second fiber reinforced layer directly on a second surface of the foam layer; wherein
the first and second fiber reinforced layers comprise a crosslinked polymer and fibers
the first and second surfaces of the foam layer are opposedly disposed to each other,
the foam layer has a compressive strength of about 3.5 to about 4.5 MPa, when measured as per ASTM-D-1621-73, and a shear strength of 1.50 to about 2.15 MPa, when measured as per ASTM-C-273, and
the fibers in the first fiber reinforced layer and in the second fiber reinforced layer are milled fibers uniformly dispersed within the crosslinked polymer.
