    • PURPOSE: A method for fabricating a needle-punched carbon composite is provided to prevent delamination or crack of layers and to save production cost. CONSTITUTION: A method for fabricating a needle-punched carbon composite comprises: a step of preparing a fiber layer of a predetermined thickness using a heat resistant fiber(S101); a step of laminating the prepared fiber layers and needle-punching while compressing the fiber layers to tight the fiber layers(S102); a step of performing thermal treatment of the fiber reinforcing material(S103); and a step of filling the fiber reinforcing material with a carbon ingredient(S104). The heat resistant fiber is an oxidized-polyacrylonitrile fiber. The fiber layer has a form of a woven fabric, a non-woven fabric, a knitted fabric, a multiaxial warp knitted fabric, a unidirectional fabric, or a web.

    • PURPOSE: A multi-layer ceramic panel and a process for producing the same are provided to differently configure the structure of foam by differently controlling the cooling temperatures at the upper and lower part when one mixture is sintered. CONSTITUTION: A method for producing a multi-layer ceramic panel comprises the steps of: applying a mixture consisting of waste glass, water glass, and trivalent alcohol in a constant thickness and width; heating the mixture; when cooling the mixture, heating the lower part of the mixture to emit the heat from an indirect heating unit; forming a vehicle noise absorbing panel section(100) at the upper part of the mixture and a sound absorbing panel section(200) at the lower part of the mixture by differently configuring the foam density and cooling rate.
    • 目的:提供一种多层陶瓷板及其制造方法,以通过在烧结一种混合物时不同地控制上部和下部的冷却温度来不同地配置泡沫结构。 构成:多层陶瓷面板的制造方法,其特征在于,包括以下步骤:将由玻璃,水玻璃,三价醇构成的混合物以恒定的厚度和宽度进行涂布; 加热混合物; 当混合物冷却时,加热混合物的下部以从间接加热单元发出热量; 通过不同地配置泡沫密度和冷却速率,在混合物的上部形成车辆噪声吸收板部分(100)和混合物下部的吸声板部分(200)。
