• the powder reinforced composite material has a diameter less than 0.8 mm, and has a volume ratio of 10%-70%;
• the powder reinforced composite material is selected from a ceramic powder material, a powder material or a magnetic powder material;
• the ceramic powder material of the powder reinforced composite material contains more than 10% of a component that is selected from at least one of a group including oxide or nitride;
• the powder material of the powder reinforced composite material contains more than 10% of a component that is selected from at least one of a group including titanate, niobium compound, barium compound, strontium compound, tantalum compound, yttrium compound, or ferroelectric;
• and
• the magnetic powder material of the powder reinforced composite material contains more than 10% of a component that is selected from at least one of a group including neodymium-iron-boron compound or samarium-cobalt compound.
