| abstract |
The invention concerns a method of producing composites with a high interface portion, in which a matrix of optionally surface-modified filler particles having affinity for the matrix phase and a particle size of not more than 200 nm is incorporated in an amount of at least 5 vol %, such that the filler particles are distributed in the matrix phase in a substantially agglomerate-free state. Preferably at least 30 vol % of the matrix phase of the composites produced in this way is in the form of an envelope which surrounds the filler particles and differs from the remainder of the matrix phase in terms of its structure and properties. The high portion of interfacial phases in this composite imparts to this material properties which differ significantly from those of a corresponding composite which has only a slight, or no, interface portion. |
