  • Publication number: 20170037221
    Abstract: The present disclosure provides a composition for preparing a lightweight transparent composite, a method of preparing a composite using the same, and a composite prepared by the method. The lightweight transparent composite having excellent impact resistance, scratch resistance, weather resistance, and high hardness can be prepared by thermally curing a mixture of a glass fiber reinforcement having a refractive index of 1.4 to 1.6 and a curable resin having a deviation in refractive index of ?0.005 to +0.005 from the glass fiber reinforcement. When the lightweight transparent composite is applied to transparent windows for automobiles, the lightweight transparent composite can be useful in enhancing fuel efficiency, achieving easier handling characteristics due to reduction in vehicle center of gravity, and improving juddering and dimensional stability even during car driving due to excellent hardness.

  • Publication number: 20160222208
    Abstract: The present invention relates to a thermoplastic resin composition and a molded article manufactured using the thermoplastic resin composition. Particularly, the thermoplastic resin composition may be reinforced with the carbon fiber. Accordingly, the thermoplastic resin composition may be obtained by mixing a carbon fiber, a silane-based coupling agent and a thermoplastic elastomer to a polyamide-6 polymer having low specific gravity, such that weight thereof may be reduced and economical efficiency may be improved. Further, parts assembly efficiency and stability of the injection molded product from the thermoplastic resin composition of the present invention may be improved by minimizing deformation after injection molding due to improved rigidity, durability and dimensional stability thereof. The thermoplastic resin composition may be used for parts of vehicle exterior material such as a panorama sunroof frame.
