Abstract
Composite materials include a steel matrix with reinforcing carbon fiber integrated into the matrix. The composite materials have substantially lower density than steel, and are expected to have appreciable strength. Methods for forming composite steel composites includes combining a reinforcing carbon fiber component, such as a woven polymer, with steel nanoparticles and sintering the steel nanoparticles in order to form a steel matrix with reinforcing carbon fiber integrated therein.
Claims13
A composite material comprising:
- a continuous matrix of sintered metal nanoparticles selected from the group consisting of steel and titanium;
- and
- at least one reinforcing carbon fiber that is at least partially encapsulated within the continuous matrix.
A composite material comprising:
- at least one reinforcing fiber structure comprising a combination of carbon fiber and ceramic fiber;
- and
- a continuous steel matrix, of sintered steel nanoparticles, disposed around the at least one reinforcing fiber structure.
