Composite thermoplastic sheets including natural fibers: no. 7,431,980; Daniel Woodman, Venkat Raghavendran and John McHugh, assignors to Azdel, Inc., Forest, VA.Composite Thermoplastic A polymer material that turns to liquid when heated and becomes solid when cooled. There are more than 40 types of thermoplastics, including acrylic, polypropylene, polycarbonate and polyethylene. Sheets Including Natural Fibers: No. 7,431,980; Daniel Woodman, Venkat Raghavendran and John McHugh, assignors to Azdel, Inc., Forest, VA. Filed 11/8/04. Issued 10/7/08. A thermoplastic composite sheet material has been issued a patent. It comprises a permeable core with a thermoplastic resin material reinforced with a web of reinforcing fibers and discontinuous natural fibers. The permeable core has a density from about 0.1 gm/cc to about 1.8 gm/cc. The permeable core includes a surface region. The composite sheet is moldable into predetermined pre·de·ter·mine v. pre·de·ter·mined, pre·de·ter·min·ing, pre·de·ter·mines v.tr. 1. To determine, decide, or establish in advance: shapes. The natural fibers are selected from a group consisting of kenaf Noun 1. kenaf - fiber from an East Indian plant Hibiscus cannabinus deccan hemp bimli, bimli hemp, Bombay hemp, Hibiscus cannabinus, kanaf, kenaf, Indian hemp, deccan hemp - valuable fiber plant of East Indies now widespread in cultivation fibers, jute fibers, flax fibers, hemp hemp, common name for a tall annual herb (Cannabis sativa) of the family Cannabinaceae, native to Asia but now widespread because of its formerly large-scale cultivation for the bast fiber (also called hemp) and for the drugs it yields. fibers, sisal fibers, coir fibers and mixtures thereof. |
