Abstract:
Presented are fiber-reinforced polymer (FRP) sandwich structures, methods for making/using such FRP sandwich structures, and motor vehicles with a vehicle component fabricated from a compression molded thermoset or thermoplastic FRP sandwich structure. A multidimensional composite sandwich structure includes first and second (skin) layers formed from a thermoset of thermoplastic polymer matrix, such as resin or nylon, filled with a fiber reinforcing material, such as chopped carbon fibers. A third (core) layer, which is encased between the first and second skin layers, is formed from a thermoset/thermoplastic polymer matrix filled with a fiber reinforcing material and a filler material, such as hollow glass microspheres. The first, second and third layers have respective rheological flow properties that are substantially similar such that all three layers flow in unison at a predetermined compression molding pressure. These layers may be formed from the same thermoset/thermoplastic polymer material, and include the same fiber reinforcing material.

Claim (Index 1):
A multidimensional composite sandwich structure, comprising:\n a first layer formed from a first polymer matrix and including a first fiber reinforcing material embedded within the first polymer matrix; a second layer formed from a second polymer matrix and including a second fiber reinforcing material embedded within the second polymer matrix; and a third layer disposed between the first and second layers, the third layer formed from a third polymer matrix and including a third fiber reinforcing material embedded within the third polymer matrix, and a filler material interspersed within the third polymer matrix, wherein the first and second fiber reinforcing materials each includes a fiber sheet with a plurality of perforations having an average width or diameter of about 10 to 100 microns and an average density of about 100-1000 perforations per square meter of the fiber sheet, and wherein the filler material includes at least 50% by volume of hollow microspheres having an average diameter of about 10 to 100 microns.
