A surrogate multilayered material and manufacturing method thereof includes a first fiber reinforced layer, the first reinforced layer including a crosslinked polymer and fibers, and a second fiber reinforced layer, the second reinforced layer including the crosslinked polymer and the fibers. A foam layer is disposed between the first and second fiber reinforced layers. Opposite faces of the foam layer are in direct contact with the first fiber reinforced layer and the second fiber reinforced layer. 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.
