Claims24
A laminate sandwich structure comprising a core which comprises carbon foam having two opposed major surfaces and a ratio of compressive strength to density of at least about 7000 psi/g/cc, wherein at least about 90% of the pore volume of the pores of the carbon foam has a diameter of between about 10 and about 150 microns and at least about 1% of the pore volume of the pores has a diameter of between about 0.8 and about 3.5 microns.
A laminate sandwich structure comprising a carbon foam core having two opposed major surfaces and having a pore distribution such that at least about 90% of the pore volume of the pores has a diameter of between about 10 and about 150 microns and at least about 1% of the pore volume of the pores has a diameter of between about 0.8 and about 3.5 microns, wherein the structure further comprises a facesheet positioned on at least one of the major surfaces of the core.
