New glass roving and mat for wind energy and marine.

At last month's JEC Composites Show in Paris, France, Owens Coming of Toledo, Ohio

This article is about the city in Ohio. For Toledo, Spain, see that article. For other uses, see Toledo (disambiguation).

Toledo is a city in the U.S. state of Ohio and the county seat of Lucas County^GR6. , introduced two new reinforcements made of corrosion-resistant Advantex E-glass. OC SE 1200 single-end roving is aimed at pultrusion Pultrusion is a continuous process of manufacturing of composite materials with constant cross-section whereby reinforcing fibers are pulled through a resin, possibly followed by a separate preforming system, and into a heated die, where the resin undergoes polymerization. , filament winding Filament winding is a fabrication technique for creating composite material structures. The process involves winding filaments under varying amounts of tension over a male mould or mandrel. and fabric production for wind-energy and marine markets. Owens Coming claims 11% higher shear strength For the shear strength of soil, see .

Shear strength in engineering is a term used to describe the strength of a material or component against the type of yield or structural failure where the material or component fails in shear. than competitive fibers, both dry and after 72-hr water boil. Other claimed benefits are 12% higher cyclic fatigue resistance, 25% higher laminate tensile strength in polyester resin, and 35% higher tensile strength in epoxy.

Also new is OC random continuous-filament mat 8635 for vacuum infusion of marine parts. It Is said to be the only CFM product tailored for this process. It reportedly allows up to 25% faster infusion because it provides an open allow channel while its thermoset A polymer-based liquid or powder that becomes solid when heated, placed under pressure, treated with a chemical or via radiation. The curing process creates a chemical bond that, unlike a thermoplastic, prevents the material from being remelted. See thermoplastic. binder prevents collapse under vacuum and resists "washing out." By allowing use of an all-glass reinforcement system, CFM 8635 is said to open up applications below the waterline to vacuum infusion. Tel: (419) 248-5939, www.owenscorning.com
