A method of producing a composite structure comprising fiber reinforced material and having a longitudinal direction is described. The method comprises the following steps: a) manufacturing a first structure comprising a first cured composite part having a first thickness and a longitudinal direction with a first end, and a number of first fiber layers extending from the first end, b) manufacturing a second structure comprising a second cured composite part having a second thickness and a longitudinal direction with a second end, and a number of second fiber layers extending from the second end, and c) arranging the first structure and the second structure so that the first end faces towards the second end, and arranging the first fiber layers and the second fiber layers so that at least a part of the first fiber layers overlap at least a part of the second fiber layers in the longitudinal direction, d) supplying liquid resin in order to impregnate the first fiber layers and the second fiber layers, and e) curing the liquid resin in order to form the composite structure comprising the first cured composite part, the second cured composite part, and an intermediate composite part including the first fiber layers and the second fiber layers.

The present invention provides a method of producing a molded article, which can be perform the continuous processes and effectively impregnate a modifying material such as metal complexes in the thermoplastic resin for short period of time. The above object is achieved by providing the method of producing the thermoplastic resin molded article which includes impregnating the high-pressure fluid having a modifying material dissolved therein, in thermoplastic resin, and continuously molding the thermoplastic resin in which the modifying material has been impregnated, into the form of a film.

The present invention is a method of producing a coating liquid-impregnated reinforcing fiber fabric 1b, including allowing a reinforcing fiber fabric 1a to pass substantially vertically downward through the inside of a coating section 20 storing a coating liquid 2 to provide the reinforcing fiber fabric 1a with the coating liquid 2; wherein the coating section 20 includes a liquid pool and a narrowed section which are in communication with each other; wherein the liquid pool has a portion whose cross-sectional area decreases continuously along a running direction of the reinforcing fiber fabric 1a, wherein the narrowed section has a slit-like cross-section and has a smaller cross-sectional area than the top side of the liquid pool, and wherein the vertical height of the portion whose cross-sectional area decreases continuously in the liquid pool is 10 mm or more.

A Chinese medicine in that form of decoction slice is prepared from 11 Chinese-medicinal material through immersing them in decoction slices, immersing them in water, mixing them with water, mixing them with water, mixing them with water, mixing them with water, mixing them with water, mixing them with water, mixing them with water, mixing them with water, mixing them with water, mixing them withwater, mixing them with water, mixing them with water, mixing them with water, mixing them with water, mixing them with water, mixing them with water, mixing them with water, mixing them with water, mixing them with water, mixing them with water, mixing them with water, mixing them with water, mixing them with water, mixing them with water, mixing them, mixing them with water, mixing them, mixingthem with water, mixing them, mixing, mixing, mixing, mixing, mixing, mixing and mixing. The invention can solve the problem that when the prior Chinese medicinal decoction pieces are impregnated, Toolong impregnation time, It usually takes a long time to get there, and soaked for a long time, Chinese herbal slices are prone to decay, Traditional Chinese medicine slices usually float above the water surface when impregnated, impregnation is not complete, traditional Chinese medicine slices usually accumulate together when impregnated, affecting the impregnation effect, complicated operation,slow impregnation, low efficiency and other difficult problems, can realize the function of automatic and high-efficient impregnation of traditional Chinese medicine slices, and has the advantages ofsimple operation, rapid impregnation, high efficiency and so on.

The invention provides a liquid impregnation device, which can make liquids uniformly impregnated in particles without being limited by the types of liquids and particles and adjust the particle oil impregnation rate in a high-precision way. The liquid impregnation device (1) comprises a roller (3) accommodating the particles; a frame (2) supporting the roller (3) to freely rotate; nozzles (11, 11..) spraying oil towards the particles; oil supply pipes (12, 12...) supplying oil to the nozzles (11, 11..); an electric motor (5) driving the roller (3) to rotate; an exhaust pipe (14) reducing pressure inside the roller (3); and a cylinder (21) making the roller (3) swing in high speed. A protruding separation projection (9) protruding towards the inner side of the roller (3) is arranged inside the roller (3). Agglutination prevention walls (10a-10e) are vertically arranged on the upper surface of the separation projection (9). Agglutination prevention walls (10f-10h) are further vertically arranged on the lower surface of the separation projection (9).

The present invention aims to sufficiently impregnate each layer of a fiber substrate group composed of fiber substrates, which are used for fiber-reinforced resin molding by a resin injection method, with a resin. To successively stack a plurality of fiber substrates, each of which has arrayed fiber bundles and is a material composing a fiber-reinforced resin along with a resin, with their fiber bundles oriented in the same direction, the plurality of fiber substrates are integrated in a state where border zones between the fiber bundles adjacent to each other in an array direction are aligned with one another among the fiber substrates.

A method is described for producing a prepreg formed by applying a matrix resin to a reinforcing fiber sheet, wherein the method can effect continuous running without clogging due to generated fuzz even at a high running speed and effect efficient impregnation of the reinforcing fiber sheet with a matrix resin. A method of producing a prepreg includes allowing a reinforcing fiber sheet to pass substantially vertically downward through the inside of a coating section storing a matrix resin to obtain a matrix resin-impregnated reinforcing fiber sheet in which the matrix resin is applied to the reinforcing fiber sheet and at least heating the matrix resin-impregnated reinforcing fiber sheet, wherein the coating section includes a liquid pool and a narrowed section which are in communication with each other, wherein the liquid pool has a portion whose cross-sectional area decreases continuously along a running direction of the reinforcing fiber sheet.
