graphitefilled
Graphite-filled refers to composite materials in which graphite or graphite-derived fillers are dispersed within a base matrix to impart desirable properties. The term is commonly applied to polymer matrices (thermoplastics or thermosets), but can also describe metal or ceramic matrices. Fillers include natural graphite flakes, synthetic graphite, or graphene nanoplatelets. The graphite provides layered carbon structures that promote electrical and thermal conduction as well as solid lubrication.
In polymer matrices, graphite fillers form conductive networks once a percolation threshold is reached, increasing electrical
Processing methods for graphite-filled composites include melt mixing, solution blending, extrusion, and compression molding. Nanoscale fillers
Applications include automotive components such as bearings and seals, piston rings, and bushings; electrical contacts and
Limitations include potential reductions in mechanical strength at high graphite load, increased density, cost considerations, and,
