Abstract:
1. A surrogate multilayered material comprising: a first fiber reinforced layer; the first reinforced layer comprising a crosslinked polymer and fibers; a second fiber reinforced layer; the second reinforced layer comprising the crosslinked polymer and the fibers; a foam layer; the foam layer disposed between the first fiber reinforced layer and the second fiber reinforced layer; where opposite faces of the foam layer are in direct contact with the first fiber reinforced layer and the second fiber reinforced layer; where 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; wherein the fibers in the first fiber reinforced layer and in the second fiber reinforced layer are milled fibers uniformly dispersed within the crosslinked polymer.
