Estimating the term…
A composite material is provided that includes at least one first material and particles. The particles have a negative coefficient of thermal expansion and the particles have a sphericity Ψ of at least 0.7. The composite material includes at least 30 vol % of the particles at a particle size of d50≤1.0 μm or at least 40 vol % of the composite material at a particle size d50>1.0 μm.
A composite material, comprising:
An adhesive bonding material, comprising a composite material including a first material and particles, the particles having a negative coefficient of thermal expansion and a sphericity of at least 0.7, wherein the particles are present in at least 30 vol % of the composite material at a particle size of d50≤1.0 μm or are present in at least 40 vol % of the composite material at a particle size d50>1.0 μm.
