A method of manufacturing a composite material for thermal shields, and a composite material manufactured by the method are proposed. The method may include preparing a mixed powder including (i) a metal powder including a powder of aluminum or aluminum alloy and (ii) a polymer or ceramic powder. The method may also include sintering the mixed powder through pressureless sintering or spark plasma sintering to produce a composite material. According to the present disclosure, a powder of polymer, ceramic, and/or metal which have a relatively low level of thermal conductivity can be compounded with a metal material including aluminum through a sintering process of powder metallurgy, such as pressureless sintering or spark plasma sintering. Thus, a heterogeneous composite material with a low-level thermal conductivity (10 W/mk or less) can be obtained, and the composite material can be used as a material for various thermal shields.

An apparatus includes a first electrode exhibiting a first Seebeck coefficient, a second electrode exhibiting a second Seebeck coefficient greater than the first Seebeck coefficient, and particles between the first and second electrodes exhibiting a third Seebeck coefficient between the first and second Seebeck coefficients. An alternating current power supply is electrically connected to the first and second electrodes. Heat is generated due to the Peltier effect at a junction between the first electrode and the particles and at a junction between the second electrode and the particles. Heat is removed due to the Peltier effect at the junction between the first electrode and the particles and at the junction between the second electrode and the particles. The particles are densified due to heating and cooling phase transitions between a higher-temperature solid phase and a lower-temperature solid phase while compressing the particles.
