Hollow high strength glass fiber
It is new reinforcement material. It is high strength, light weight 20-30% lighter than solid glass fiber, high rigidity, low dielectric constant, low thermal conductivity, better in thermal insulation. It is used in decorating plates inside plane, as nonstructural material for skin. It is not only lighten dead weight, but also improve stealth property of plane. It is allowed good transmit of electromagnetic wave so that plane are difficult to be found by radars.
