A vacuum port base comprises an upper face, a lower face, a first channel, and a second channel. The upper face is configured to interface with a vacuum port. The lower face is configured to interface with a surface of a tool. The first channel formed in the lower face is configured to receive an edge breather. The second channel formed within the vacuum port base is configured to receive the vacuum port such that the vacuum port is in fluid communication with the first channel and the edge breather to remove gases from a composite structure.

An RTM molding device and an RTM molding method which enable resin impregnation of even large members and thick members without causing non-impregnated regions or fiber wrinkle, and yield a molded body having superior toughness and excellent precision. In the RTM molding device, a surface molding layer, which is disposed between a fiber-reinforced base material and a molding die, has a plurality of through-holes formed therein, and has sufficient rigidity that the thickness does not substantially change under the pressure inside the cavity when the inside of the cavity is placed under reduced pressure, and a resin diffusion portion, which is located on the side of the surface molding layer opposite the fiber-reinforced base material, and comprises a resin flow path formed so as to connect with the plurality of through-holes of the surface molding layer, are provided on at least one surface of the fiber-reinforced base material.

A resin supply material is used for molding a fiber-reinforced resin and includes a continuous porous material and a resin. The continuous porous material has a bending resistance Grt of 10 mN.Math.cm or more at 23 C., and a bending resistance ratio Gr of 0.7 or less, the bending resistance ratio Gr being expressed by the formula:

Gr=Gmt/Grt Gmt: bending resistance of continuous porous material at 70 C.

A connecting port arrangement for use in an apparatus for producing a composite material component comprising a base member attached to a surface of a foil adapted to seal a mold of the apparatus for producing a composite material component. The base member is provided with a channel extending therethrough. The connecting port arrangement further comprises a punch member adapted to be inserted into the channel formed in the base member and provided with a cutting device suitable to cut at least one opening into the foil.

An actuatable flow media for the control of a flow rate of a liquid through the flow media, the actuatable flow media comprising a base having at least one cavity formed therein, at least one aperture formed in the cavity defining a liquid flow path for the entry of liquid into or exit of liquid from the flow media; a flexible membrane arranged in spaced relation with the base and defining a liquid flow path through the flow media; and an elastically deformable element arranged in the cavity and extending between the base and the flexible membrane for actuation between at least a first configuration in which the element is substantially undeformed and the liquid flow path through the at least one aperture is open and a second configuration in which the element is substantially deformed and the liquid flow path through the at least one aperture is closed.

A method for the production of plastic parts, in particular of composite parts, utilizes at least two components to be mixed in a mixing chamber and a cavity formed between a first and a second mold half of a molding tool. The cavity comprises a mold part section and a sprue section, and the sprue section or the mold part section is used as mixing chamber.

A mold for a production device for production of fiber-reinforced components by means of an injection process is provided. The mold has a mold surface to form a surface of the fiber-reinforced component, the mold surface having a first partial area and a second partial area and in which the mold has an injection area for injection of matrix material into fibrous material situated on the mold surface through the second partial area of the mold surface and evacuation area for evacuation of a mold volume bounded by the mold through the first partial area of the mold surface.

The invention relates to a curing mold (10) for manufacturing a turbomachine component made of composite material from a preform (200), comprising: a first and a second body (11, 12) defining an air gap receiving the preform; at least one primary channel (21) arranged in the first and/or the second body; an injection member (22) of a pressurized fluid in the primary channels; at least one secondary channel (23), in which a piston (24) slides, which delimits, on the one hand, a first chamber (26) in communication with the or a primary channel and, on the other hand, a second chamber (27) in communication with the air gap, and which is designed to compress thermosetting resin which has entered the second chamber from the preform in the air gap, so as to put the preform under hydrostatic pressure.

A system is disclosed herein. The system includes a mold including a cavity, the cavity configured to receive a preform having a three-dimensional woven fabric and a port formed through the mold and into the cavity, wherein the port is configured to introduce a mixture of a resin and a hardener into the cavity, the resin filling the cavity and penetrating into the preform

A tool for fabricating a control surface is disclosed. In various embodiments, the tool includes a first block defining a longitudinal direction running between a leading edge end and a trailing edge end; a first sidewall spaced a first lateral distance from the first block to form a first closeout channel running in the longitudinal direction between the first block and the first sidewall; and a second sidewall configured to form a second closeout channel running in the longitudinal direction, the second closeout channel disposed laterally opposite the tool from the first closeout channel.
