  • Patent number: 9302349
    Abstract: There are often difficulties in producing materials that are wide and long, such as from the availability of properly dimensioned feedstock materials, processing costs, engineering challenges, and the like. As such, new methods for joining materials are needed. The present invention relates to composite materials, such as a sandwich composite, articles prepared from a composite material, and methods for preparing articles, that employ an edge joint. The edge joint may be employed for attaching the composite material to another composite material, or for attaching it to a monolithic material.

  • Patent number: 9233526
    Abstract: The invention relates to multi-layered composite materials and methods for making multi-layered composite materials having good adhesion between the layers. The adhesion between a polymer layer and a metal layer of a multi-layered composite material may be improved by a process including a step of pre-treating a surface of the metal layer prior to contacting the metal surface with the polymer layer, and by including filler particles in the polymer layer. Using this approach, it is possible to increase the peel strength by about 10% or more, by about 20% or more, by about 40% or more, or by about 100% or more, compared with an otherwise identical composite material that does not include both of these features.
