Feel free to have a look at our videos for a look at some actual fabrication. But, briefly EasyPreg is heated to a core temperature of 400°F, activating the resin; EasyPreg is then immediately formed (usually by vacuum) over a mold. When EasyPreg has cooled to 100°F the resin has set and the molding process is complete. Fabrication is completed no differently than with any other composite process. Glossary of Terms Twill - A type of weave in which the warp and/or weft strands are woven a minimum of 2 over/2 under. This yields a herringbone or diaganol pattern in the fabric. Twill is used in composites to provide the strongest fabric in all directions while allowing sufficient moldability of the fabric over the mold. Weft- In weaving, the fill or horizontal strands that are woven across the warp strands. Warp-In weaving, the set of lengthwise strands through which the weft strands are woven. Satin - A type of weave in which the warp and/or weft strands are woven a minimum of 4 over/4 under. In composite fabrication satin is used to provide more rigidity in one direction more than another without adding weight to the device. Carbon Fiber - (also called graphite fiber) a material consisting of extremely thin fibers about 0.0002–0.0004 inches (0.005–0.010 mm) in diameter and composed mostly of carbon atoms. The carbon atoms are bonded together in microscopic crystals that are more or less aligned parallel to the long axis of the fiber. The crystal alignment makes the fiber incredibly strong for its size. Several thousand carbon fibers are twisted together to form a yarn, which may be used by itself or woven into a fabric. Carbon fiber has many different weave patterns and can be combined with a plastic resin and wound or molded to form composite materials such as carbon fiber reinforced plastic (also referenced as carbon fiber) to provide a high strength-to-weight ratio material. Fiberglass - is material made from extremely fine fibers of glass. It is used as a reinforcing agent for many polymer products; the resulting composite material, properly known as fiber-reinforced polymer (FRP) or glass-reinforced plastic (GRP), is called "fiberglass" in popular usage. Kevlar - is Dupont's registered trademark for a light, strong para-aramid synthetic fiber, related to other aramids such as Nomex and Technora. In O&P it can be used in combination with carbn fiber and/or fiberglass to add flexibility to a device without risking fracture of the device. |
