The low density, semi-rigid polyurethane foams of the present invention may find use in producing lightweight, rapidly erected barriers for protection of people such as soldiers, police officers and fire fighters from pursuit by adversaries. Barriers made with the inventive foam may also be used to limit access to already secured areas.

    摘要： The present disclosure is directed to a process for forming a reinforced ultraviolet (UV) radiation-curable composite. The composite may be formed by applying reinforcing layers and resin layers to a substrate. The resin composition may include an aliphatic urethane acrylate oligomer, a polyfunctional acrylate monomer, and a photoinitiator. The composite formed on the substrate may be exposed to UV radiation to cure the composite on the substrate. The composite may be characterized in that it is cured within 10 minutes of exposure to UV radiation and does not exhibit oxygen inhibition effects, such as, for example, surface tack. The reinforced UV-curable composite may find utility, for example, as a rapid field repair patch in aerospace applications, among others.
