摘要:
The present invention relates to a stack of fibrous materials including at least two unidirectional carbon fiber layers, each extending in different directions, wherein each one of the unidirectional layers is connected by means of at least one of the surfaces thereof to an adjacent web of thermoplastic fibers, at least one web being inserted between two consecutive unidirectional layers, characterized in that the link between each unidirectional layer and each adjacent web is provided by the web, by weld points which produce an intermittent overall weld, and in that said weld points also guarantee the cohesion of the stack, as well as the method for manufacturing same.

The present invention provides an intermediate material composed of an assembly of overlapping and interlaced tapes, characterized in that at least some of the tapes, preferably all of the tapes, known as veiled tapes, are composed of a series of reinforcing yarns or filaments that extend in a direction parallel to the length of the tape to form a unidirectional sheet that is associated on each of its faces with a nonwoven formed from thermoplastic fibers, said two nonwovens providing said veiled tape with cohesiveness because of their thermoplastic nature, to a production method using said material for producing composite parts, and to the composite parts obtained.
摘要:
The invention relates to an intermediate product intended for the production of a composite part in combination with a resin matrix, formed by at least two unidirectional sets of reinforcing yarns, the yams of each set extending in a different direction, whereby the sets are interlinked by means of stitching or knitting using at least one stitching or knitting yarn. The invention is characterized in that the stitching or knitting yarn has a yarn count of less than or equal to 30 dTex, preferably less than or equal to 25 dTex, in accordance with standard EN ISO 2060.

A device for placing a reinforcing tape in a tissue of the human body includes an introducer having an elongated flexible body, at each of both ends of the body, pulling means, between both ends, a cavity for receiving the tape, and, at the cavity, means for cutting the body into two portions separable by pulling exerted on the pulling means. The cutting means includes at least one aperture provided in the wall of the cavity and intended for the passage of a cutting tool. This device is applicable to the treatment of cystoceles.
摘要:
A method for producing a diffusion layer of an electrochemical device, including: superimposition of multiple unidirectional webs of carbon filaments, filaments of each web positioned parallel with, and next to, one another; needle punching of the webs, breaking a proportion of the filaments such that broken portions of the filaments are tangled with other filaments of the webs; and cutting a proportion of the multiple unidirectional webs, the carbon filaments forming one electrically conducting outer surface of the diffusion layer. The needle punching is accomplished all the way through the multiple unidirectional webs, and/or through two principal opposite faces of the multiple unidirectional webs, and/or with an impact density against the multiple unidirectional webs of between approximately 100 and 300 impacts/cm2.
