A system for constructing a composite structure includes a braiding machine, a winding tool and a forming machine. The composite structure is constructed of a wound tubular braiding. The wound tubular braiding is constructed of a biaxial or triaxial tubular braid of unidirectional tape.

Disclosed is a rigid and monolithic composite under-vehicle protector containing phenolic felt and a polyurethane material applied by spraying on the phenolic felt. A production method for the under vehicle protector is also disclosed.

A single stage OPF-to-carbon preform shape forming method includes positioning an oxidized PAN fiber preform with a female forming tool, positioning a vacuum bag over the oxidized PAN fiber preform, and vacuum forming the oxidized PAN fiber preform into a shaped body. The vacuum formed shaped body (while still in the shape forming fixture) may be loaded into a carbonization furnace and carbonized. The vacuum bag may be burned away in the carbonization furnace during carbonization.

During a manufacturing method, a preform is arranged with a plurality of grips. The preform includes a stack of a plurality of layers of material. The grips are disposed along a periphery of the stack. The preform is formed into a shaped body. The forming includes pressing a die against the stack and gripping the stack with the grips during the pressing of the die. The gripping includes asynchronously gripping the stack with at least some of the grips.

Method of moulding a moulding material to form a moulded part of carbon fibre-reinforced resin matrix composite material in which a sheet moulding compound is moulded which can provide panels, for example for use as vehicle body panels, which have the combination of very low thickness, very light weight, very low warping and surface defects, and very low anisotropy with regard to localised fibre and resin distribution and their associated appearance and mechanical properties.

Provided is a method for manufacturing a fiber reinforced resin molded article capable of effectively reducing the occurrence of a preform with poor resin impregnation, and such a manufacturing device thereof. After it is detected that a predetermined amount (the same amount) of resin has been individually poured into a plurality of cavities provided in a mold, the fiber layers of preforms are impregnated (compressively filled) with resin. Pressure sensors for detecting a resin injection amount are used. When closing runners, a small gap is formed in the runners.

A mold is for press molding a metal plate and a resin material to produce a metal-resin composite. The mold includes an upper mold and a lower mold that sandwich the metal plate and the resin material. A cavity for arranging the resin material is provided by the upper mold and the lower mold. The upper mold has a recess into which the resin material leaking from the cavity is caused to flow.

An assembly for preforming a reinforced fabric sheet may have at least one frame and a plurality of gripping devices. Each gripping device of the plurality of gripping devices may be suitable for gripping an edge portion of the reinforced fabric sheet. The assembly may have a moving system with a plurality of first moving devices. The movement of each first moving device may be independent of the other first moving devices. Each gripping device of the plurality of gripping devices may be associated with a first moving device. The first moving device may be suitable for moving each gripping device of the plurality of gripping devices independently of the others.

A method for making a three-dimensional composite part with a thermoplastic matrix and continuous reinforcement. A pre-impregnated fibrous perform is obtained by three-dimensional knitting. The preform is placed on the punch or in the matrix of a tooling, defining between them a sealed closed cavity. The tooling is closed so as to apply a first pressure to the preform. The cavity is brought to the melting temperature of the polymer impregnating the preform by maintaining the first pressure. The cavity comprising the preform is cooled to a temperature suitable for demolding by maintaining the second pressure. The mold is opened and the part is demolded.
