Abstract: The present teachings contemplate a method that includes a step of providing a first amount of esterified reaction product of an acid and an epoxy-based material. The esterified reaction product may be further reacted an epoxy resin to form a polymeric epoxy. The resulting material may have a generally linear backbone, foaming and curing capability and flame retardant properties.

Abstract: The present teachings contemplate a method comprising providing a first and second substrate, locating an initiator onto a surface of the first or second substrate, the initiator including a substance for initiating polymerization of a polymerizable adhesive, locating the polymerizable adhesive onto a surface of the first and second substrate, the adhesive including a monofunctional, difunctional, or multifunctional methylene malonate, or cyanoacrylate, and contacting first and second substrate.

Abstract: A multi-layer composition to be located onto a substrate. The composition comprises a bi-layer construction, including a first layer and a second layer, the first layer having a high elastic modulus and tensile strength in comparison to the second layer. The second layer includes a blowing agent such that, when cured, the first layer is spaced away from the substrate. The compositions of the first layer and second layer are similar, thus enabling the reconstitution of scrap into usable material for forming another multi-layer reinforcement.

Abstract: The present teachings generally provide for a reinforcing patch for stiffening vehicle panels. The reinforcing patch may be fabric free (e.g., free of any reinforcing layer). The reinforcing patch may be cut into small shapes, complex shapes, or both. The stiffening material may be free of a mesh or a fabric, which may allow the reinforcing patch material to be easily produced and easily reprocessed. The reinforcing patch may include one or more reinforcing particulates in combination with one or more discontinuous fiber components to obtain stiffness comparable to traditional patches which include a mesh/fabric layer.
