  • Patent number: 8962735
    Abstract: Prepreg compositions and methods of making them from particles and a binder composition are disclosed. The methods may include placing the particles on a moving conveying belt and applying the binder composition to the particles on the moving conveying belt to form a moving mass. Alternate methods may include first placing the binder composition on the moving conveying belt and then applying the particles to the binding composition to form the moving mass. The methods may further include passing the moving mass through one or more pairs of opposed, compacting rolls, where the particles and the binder composition are pressed into further contact while passing through the compacting rolls to form the prepreg. The binder composition in the prepreg may include monomers and/or oligomers of a polymer that are capable of polymerizing into the polymer under polymerization conditions.
