COMPOSITE MATERIAL AND FILLER THEREFOR

摘要

A composite material comprises a matrix (4) and a filler (5). The filler has at least one mat (1) consisting of fibres and fine granular additive (3) dispersed on and affixed to the mat. The fibres and the additive have heat resistance sufficient to withstand heating temperatures at which they are respectively composited with the matrix. The additive has a density different from that of the matrix.
