  • Patent number: 10508204
    Abstract: Photo-protected microcapsules containing a photopolymer composition are dispersed in an epoxy coating to form an autonomic self-healing material. The capsule shell wall is formulated to protect the photopolymer composition from electromagnetic radiation exposure prior to rupture of the capsule shell, so that the photopolymer composition (e.g., a UV curable epoxy resin) remains active until triggered by damage to the capsule shell. Carbon black pigment is a suitable UV protector for the capsules. Upon sufficient damage to a region of the coating, the capsules will rupture and the photopolymer composition will fill and cure in and/or around the damaged region in the presence of electromagnetic radiation, achieving autonomic healing of the damaged coating.

  • Patent number: 10363708
    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.
