Polyurethane fiber composite

A polyurethane fiber composite developed by Bayer Material Science is being applied to the automotive industry.

The manufacture of a lightweight sandwich component made of polyurethane fiber composite materials involves spraying a package consisting of a light honeycomb core (e.g. cardboard) and two fiber outer layers on both sides with the heat-activated 2-component polyurethane system Baypreg F and compressing it in a compression mold at approximately 130 °C. This enables components to be manufactured with weights of significantly less than three kilograms per square meter, i.e. up to 60 percent lighter than corresponding components made of conventional materials such as wood or sheet metal.

Time may tell if this has an impact (no pun intended) in the construction materials industry.
