Title:
METHOD FOR MANUFACTURING COMPOSITE MATERIAL FOR THERMAL SHIELDS, AND COMPOSITE MATERIAL FOR THERMAL SHIELDS MANUFACTURED THEREBY
Document Type and Number:
WIPO Patent Application WO/2021/153851
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing a composite material for thermal shields, and a composite material for thermal shields manufactured thereby, the method comprising the steps of: (a) preparing a mixed powder including (i) a metal powder including a powder made of aluminum or an aluminum alloy and (ii) a polymer or ceramic powder; and (b) preparing a composite material by sintering the mixed powder by pressureless sintering or spark plasma sintering. According to the method for manufacturing a composite material for thermal shields of the present invention, as a polymer, ceramic, and/or a metal powder having relatively low thermal conductivity is combined with a metal material including aluminum through a sintering process using powder metallurgy such as pressureless sintering, spark plasma sintering, etc., it is possible to realize heterogeneous composite materials having low thermal conductivity (around 10 W/mk), and such composite materials may be applied to various materials for thermal shields.
