Title: Chemical treatments for fibers and wire-coated composite strands for molding fiber-reinforced thermoplastic composite articles
Inventor: WOODSIDE ANDREW B
IPC: C08J5/06
Filed: 1997-08-07
Abstract: In one general aspect, the invention involves applying a chemical treatment to fibers, such as reinforcing fibers suitable for making a composite article, so as to size and/or preimpregnate the fibers. The chemical treatment has a relatively low viscosity and is substantially solvent-free and non-radiation curable. Heat energy may be employed to lower the viscosity and improve the wetting ability of the applied treatment and/or to increase the molecular weight of, or otherwise cure, the treatment with essentially no generation of solvent vapor. The treated fibers are used to form a composite strand, which may be subsequently processed in-line or off line into a composite article having fibers disposed in a polymeric matrix. Another general aspect relates to encased composite strands, in thread or pellet form, and to wire-coating methods and apparatus for making them. The strands are moldable into fiber-reinforced thermoplastic composite articles. Each strand is made from fibers, including reinforcing fibers and optionally fibers of a matrix material, that are impregnated with a chemical treatment so that the treatment is disposed between substantially all of the fibers.

Filed: 2003-11-12
Abstract: L'invention concerne un micro-actionneur bistable constitué d'une première et d'une plaquette silicium sur isolant fusionnées sur une couche de contact électrique. Un revêtement à rainure en V définit un axe optique. Une source de signal optique, collamitée dans la rainure en V, couple un signal optique à un port optique dans la rainure en V. Une surface miroir placée sur un élément de transfert bloque ou réfléchit le signal optique. L'élément de transfert présente un point de support sur sa première et seconde extrémité. Le miroir bloque ou réfléchit l'axe optique. Une structure extensible applique une force de compression entre le premier et le second point de support de l'élément de transfert, le long d'un axe de compression, ce qui permet de maintenir l'élément de transfert dans un premier état courbé et dans un second état courbé. Un signal de commande appliqué à un élément de chauffage dans la structure extensible réduit la force de compression, ce qui déclenche le second état de l'élément de transfert.
