Publication number: 20110274907Abstract: Curative fibre components comprise one or more fibres for filaments of curative suitable to cure curable resins such as thermoset resin. In curative fibre components comprising a plurality of fibres of curative, the fibres can be commingled, such as twisting, to form a thread or yarn. Curative fibre components can be used to form a material in the form of a sheet, fabric, layer, textile or mat of woven or non-woven curative fibres. Curative fibre components can be used to produce composite materials such as fibre reinforced resinous composite materials. The curative fibre components can be commingled, including interwoven, stitched and layered with other fibres or fibrous materials, such as fibrous reinforcement, fibrous curable resin, fibrous thermoplastic, other non-reinforcing fibres to form composite materials, prepregs, preforms and articles.Type: ApplicationFiled: November 24, 2009Publication date: November 10, 2011Inventors: Mark Raymond Steele, Andrew Gibbs, Amy Grace Atinkson

Patent number: 8044142Abstract: This invention provides a polymer alloy comprising a polyphenylene sulfide resin and a polyphenylene ether resin. This polymer alloy can eliminate molding whitening which, upon molding, occurs on the surface of the molded product, can impart excellent surface appearance and flame retardance, and further can improve balance between heat resistance and toughness (impact strength) and mechanical strength. The resin composition comprises 45 to 99 parts by weight of a polyphenylene sulfide resin comprising (a) 0 to 96% by weight of a specific linear polyphenylene sulfide resin and (b) 100 to 4% by weight of a specific crosslinking-type polyphenylene sulfide resin. The resin composition further comprises (c) 55 to 1 part by weight of a polyphenylene ether resin. Further, the resin composition comprises (d) 1 to 20 parts by weight, based on 100 parts by weight in total of components (a) to (c), of a styrene copolymer and/or an ethylene copolymer containing any one functional group of glycidyl and oxazolyl groups.Type: GrantFiled: September 21, 2005Date of Patent: October 25, 2011Assignee: Asahi Kasei Chemicals CorporationInventors: Yoshikuni Akiyama, Minoru Sakata

Publication number: 20110224345Abstract: This invention relates to a low dielectric resin varnish composition for laminated printed circuit boards, wherein the resin composition includes (A) Dicyclo-pentadiene-Phenolic Novolac resin (abbreviated as DCPD-PN); or (B) at least one kind of dicyclopentadiene Phenolic Novolac Epoxy resins(DCPD-PNE, referred to as Resin 1); or (C) a novel Dicyclopentadiene-Dihydrobenzoxazine resin (DCPD-BX, referred to as Resin 2); or the mixture of (B) and (C), and (D) Flame retardant agent, curing agent and accelerating agent solutions. Because all of component (A) DCPD-PN, component (B) DCPD-PNE and component (C) DCPD-BX in this resin varnish composition contain a saturated multi-cyclic structure of dicyclopentadiene, the resin varnish shows lower dipole, dielectric constant (Dk), dissipation factor (Df) and moisture absorption; and via adding a brominated or phosphorus flame retardant, the composition exhibits high thermal stability characteristic.Type: ApplicationFiled: March 15, 2010Publication date: September 15, 2011Inventors: Ming Jen TZOU, June Che Lu, Yi Cheng Lin
