摘要： Disclosed is a brake friction material for stainless steel brake discs, as a non-asbestos-based organic friction material not including asbestos. The brake friction material can enhance braking characteristics and wear resistance of a stainless steel brake disc. The brake friction material for stainless steel discs comprises a fiber base, a binder, a filler and a friction modifier. In particular, the friction modifier is included in an amount of about 10 to 22% by volume based on the total volume of the brake friction material composition and comprises zirconium oxide (ZrO2), iron oxide (FeO), graphite (C), tin (Sn) powder and alumina (Al2O3).

摘要： This invention relates to a paper friction material and a method of manufacturing the same, wherein the paper friction material is configured such that dispersibility and bondability are increased between a filler and a matrix. The paper friction material which is suitable for use in a vehicle, includes a friction base including pulp and a coating layer formed on the friction base using a mixture of latex and a functional material. The OH reactive group of the pulp and the aromatic ring of the latex are hydrogen-bonded so that the friction base and the coating layer are coupled with each other.

摘要： An apparatus for displaying a floating image is disclosed. The apparatus includes a light source that extends in a planar direction and emits light for realizing the floating image, a collecting lens, which extends parallel to the light source and refracts the light, a reflective plate, which faces the collecting lens and reflects the light that is refracted at the collective lens, and a dihedral reflector array, which extends in a planar direction and includes mirrors extending in directions intersecting each other, where a first surface of the dihedral reflector array facing the reflective plate such that the reflected light is incident on the first surface, and the reflected light is emitted from a second surface of the dihedral reflector array by being reflected by the mirrors, thereby realizing the floating image at a position spaced apart from the second surface.
