Glass/PET yarn blends strength & light weight. (Composites).Johns Manville's Engineered Products Group in Denver has introduced Comfil-G, a family of commingled yarns consisting of continuous glass and PET filaments. Another Comfil-G product with glass and polypropylene filaments will be introduced this year. Johns Manville says the glass/PET product can be used to produce lightweight plastic molds with improved tensile strength tensile strength Ratio of the maximum load a material can support without fracture when being stretched to the original area of a cross section of the material. When stresses less than the tensile strength are removed, a material completely or partially returns to its . It can also be used for 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. , hot-press forming, winding, and braiding. Glass/PET yarn resists temperatures up to 120 C (248 F). It also reportedly provides good paintability and adhesive bonding Adhesive bonding The process of using an adhesive to manufacture an assembly. The adhesive-bonded assembly is known as an adhesive joint, and the materials to which the adhesive adheres are known as the adherends. . Different versions are available with a range of glass content and elongation elongation, in astronomy, the angular distance between two points in the sky as measured from a third point. The elongation of a planet is usually measured as the angular distance from the sun to the planet as measured from the earth. . Tel: (303) 978-2000, www.jm.com |
