Title:
COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2007/049748
Kind Code:
A1
Abstract:
A composite material containing carbon fiber structures of a novel structure
which have properties desirable for fillers for composite materials and, when
added in a small amount, can improve physical properties including electrical
properties, mechanical properties, and thermal properties without impairing
the properties of the matrix. The carbon fiber structures each has a three-dimensional
network form constituted of carbon fibers with an outer diameter of 15-100 nm
and has a granular part which bonds the carbon fibers to one another and from which
the carbon fibers project, the granular part having been formed in the course
of growth of the carbon fibers. The carbon fiber structures contain boron. The
composite material is obtained by incorporating the carbon fiber structures
into a matrix in an amount of 0.001-30 mass% based on the whole composition.
