Abstract:
1. A method of forming a composite material comprising: (a) forming a first lattice construction from a plurality of solid particles, said construction being formed so as to have one or more gaps between the particles, said gaps being at least partially filled with a first fluid material; (b) partially displacing the first fluid material with an invading fluid material such that the invading fluid material partially penetrates the gaps in the lattice construction; (c) at least partially solidifying the invading fluid material which penetrated the gaps in the lattice construction to form a composite material; and, (d) removing at least a portion of the solid particles from the composite material, thereby forming at the location of the removed portion one or more pores in the solidified invading material, wherein a portion of the first fluid is not displaced by the invading fluid; and at least partially solidifying the first fluid material.
