  • Publication number: 20120214910
    Abstract: The present invention relates to reed composite which can be used as building material, method for manufacturing the composite, and building material using the composite. More specifically, the present invention relates to reed composite which comprises 55 to 75 wt % of reed stalk having a particle size of 40 to 180 mesh wherein its joints are removed and 25 to 45 wt % of thermoplastic polymer impregnated into fibers of the reed stalk, thereby being eco-friendly and having higher strength and no swelling. Further, reed used as raw material of the composite according to the present invention has many advantages as interior and exterior material since it has similar texture and pattern to natural wood and a higher weight than cornstalk, bagasse or rice straw which are non-wood materials. Moreover, the composite of the present invention can be used as various building materials such as interior material, exterior finishing material and landscaping material.

  • Publication number: 20120094105
    Abstract: Disclosed are a bagasse composite, a method for preparing the composite, and an interior material using the same. More particularly, the composite includes 55-75 wt % of fibers and 25-45 wt % of thermoplastic polymer, wherein the fibers are obtained from bagasse and have a particle size of 40-120 mesh, and a length to diameter ratio of 3:1 to 5:1. Thus, the composite shows a high strength, and is not swelled. Also, the disclosed composite has similar natural texture and patterns to natural wood, and can be used for manufacturing a product capable of substituting for various interior materials and treated wood.
