METHOD FOR PRODUCING COMPOSITE SHEET AND COMPOSITE SHEET

摘要

PROBLEM TO BE SOLVED: To obtain a composite sheet which has a high degree of orientation of a fibrous filler in the thickness direction of the sheet even when the content of the filler is high, or the filler has a high aspect ratio and is high in anisotropic thermal or electric conductivity in the thickness direction of the sheet and excellent in heat resistance, durability. mechanical strength, and adhesion to a heating element. SOLUTION: In a method for producing the composite sheet. while a composition for the sheet comprising the magnetic fibrous filler (A) and a binder (B) which can be cured by heat and/or light is rolled into a sheet. and the filler is oriented in the thickness direction of the sheet by applying a magnetic field to the sheet in the thickness direction of the sheet. the sheet is cured or semi- cured by heat and/or light.
