Publication number: 20080199668Abstract: The process according to the invention comprises: a step in which chopped filaments and discontinuous PVOH fibers are dispersed in a process water, followed by a step in which a bed is formed in a forming device by passing the dispersion over a forming cloth through which the process water is drained, the filaments and fibers being retained on said cloth, followed by a heat treatment step in a stoving device. The PVOH fibers impart rigidity to the bed of fibers being formed.

Patent number: 7069628Abstract: A plant for the manufacture of mats formed of continuous yarns originating from bobbins and thrown onto a conveyor belt. The plant includes at least one bobbin supported on a spindle, a guide for guiding a fiber bundle leaving the bobbin, a mechanism for pulling the fiber bundle, and a mechanism for throwing the yarns that make up the fiber bundle onto the conveyor belt. The guide for guiding, the mechanism for pulling, and the mechanism for throwing the fiber bundle are fixed, located in the continuation of one another and at one and a same level. The throwing mechanism includes a swinging arm for throwing the yarn transversely to the conveyor belt and the guide is arranged such that the fiber bundle is paid out from the bobbin from the outside.Type: GrantFiled: March 20, 2002Date of Patent: July 4, 2006Assignee: Saint-Gobain Vetrotex France S.A.Inventors: Michel Droux, François Roederer, Manuela Astro, Filippo Mauri

Publication number: 20050250403Abstract: The invention relates to a mat comprising discontinuous natural fibers and discontinuous glass fibers, and to the fibrous structures that can be produced using said mat, said structures being intended to reinforce composites. The presence of natural fibers in the mat gives the latter the property of being easy to handle, especially by eliminating the annoying tendency of mats made exclusively of glass fiber to wrinkle uncontrollably. In addition, the mechanical properties of the final composite are remarkable, in particular with regard to the tensile modulus and flexural modulus.Type: ApplicationFiled: February 27, 2003Publication date: November 10, 2005Applicant: Saint-Gobain Vetrotex France S.A.Inventors: Michel Droux, Francois Roederer, Francois Vinet

Publication number: 20050244624Abstract: The invention relates to a process for manufacturing a chopped strand mat that can be used for the reinforcement of thermosetting resins. The process comprises a step of dispersing strands, that are chopped and dried after sizing with a sizing liquid comprising an organosilane and a film former, in a white water, then a step of forming a web by passing the dispersion over a forming wire, through which the white water is drained, the strands being retained on said wire, then a step of applying a binder and then a heat treatment step. Chopped strand mats with a uniform mass per unit area of generally between 50 and 1100 g/m2 are obtained. A few chopped strands are broken down into filaments within the mat.Type: ApplicationFiled: March 5, 2003Publication date: November 3, 2005Inventor: Michel Droux
