ABSTRACT:
A method of forming a pin-reinforced foam core sandwich structure (10) including placing first and second face sheets (12), (14) on opposite sides of a foam core (16), the foam core (16) having at least one low density sublayer (28), an optional high density foam sublayer (26), and a plurality of Z-pins (20) positioned therein. The combination of the foam core (16) and face sheets (12), (14) forming a preliminary structure. Autoclave curing the preliminary structure according to a particular temperature and pressure regime, to crush the at least one low density sublayer (28) and to force the plurality of Z-pins (20) into the first and second face sheets (12), (14). Also provided is a pin-reinforced foam core sandwich structure (10) formed by the above process. In a second embodiment, all, or a portion, of the foam core (16) is removed using a solvent to dissolve the foam core (16), but not the Z-pins, to create a column structure (40).
