Abstract: The present application relates to a composite material and a method for molding the same. Firstly, components to be pressed is disposed in a gas-isolation element, and located between two pressing plates. Next, a plate is disposed based on a location of a prepreg element of the components, and then a hot pressing step is performed. After the hot pressing step, a cooling step is performed, thereby producing the composite material of the present application. A dimension of the composite material can be easily adjusted to meet requirements of various applications.

Abstract: The present application relates to a mold for carbon fiber composite material. The mold comprises a first mold, a second mold, a frame mold and a plurality of stopping mold. The frame mold is disposed between the first mold and the second mold, and the stopping mold is disposed between the first mold and the frame mold. An enclosing space is defined by the frame mold, and protruding portions of the first mold and the second mold are protruded into the space. The stopping mold is pressed against the first mold and the frame mold. The carbon fiber composite material with a corresponding thickness can be conveniently produced with the mold of the present application by replacing the stopping mold, thereby being suitable to various fields of the application.

Abstract: A method of manufacturing resin composition includes following operations. A nano-particle filler, a micro-inorganic particle, and a resin are stirred and mixed to form a mixture. The mixture is centrifuged at a high speed to form an upper layer mixing liquid and a lower layer mixing liquid. The upper layer mixing liquid is taken out and obtains the resin composition.

Abstract: The present invention relates to carbon fiber composites and a method for producing the same. By reducing specific transition metal ions with a specific concentration, the method for producing the carbon fiber composites can form nanoparticles of a transition metal on an outer surface of a titanium dioxide layer encapsulating a carbon fiber to produce the carbon fiber composites. The nanoparticles of the transition metal directionally contact the titanium dioxide layer, so that the carbon fiber composites have synergistically photocatalytic activity.

Abstract: A manufacturing method for an antibacterial fiber includes the following steps. A dipping step is performed to soak a conductive fiber in a solution, in which the solution includes an ionic compound, and the ionic compound includes a metal cation. An oxidation step is performed by using the conductive fiber as an anode, such that an antibacterial material produced by the solution is adhered to a surface of the conductive fiber, in which the antibacterial material includes a metal oxide.

Abstract: A method and an apparatus for manufacturing pre-preg are described. In this method, a fiber bundle of a fiber bundle roll is transferred to a wiping wheel and is flattened by several rollers. These rollers are arranged in sequence between the fiber bundle roll and the wiping wheel and are separated from each other. The fiber bundle is transferred by using the wiping wheel to impregnate the fiber bundle with a resin on a wheel surface of the wiping wheel. A tension of the fiber bundle on the rollers and the wiping wheel is controlled by using a tension controller during the transfer of the fiber bundle by the roller and the wiping wheel. The fiber bundle impregnated with the resin is wound by using a winding roller.
