1 COMPOSITE MATERIAL COMPRISING AT LEAST ONE FIRST MATERIAL AND PARTICLES WITH A NEGATIVE COEFFICIENT OF THERMAL EXPANSION AND ADHESIVE BONDING MATERIAL COMPRISING THE COMPOSITE MATERIAL

摘要

The present invention relates to a composite material comprising at least one first material and particles, wherein the particles have negative coefficient alpha of thermal expansion, and have sphere degree psi of at least 0.7. In addition, the composite material comprises at least 30 vol% of the particles at the particle size of d_50 = 1.0 μm or comprises at least 40 vol% of the particles at the particle size of d_50 1.0 μm.
