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: Light weight composites with high flexural strength comprise epoxy foam sandwiched between two layers of facing material have high strength and low weight and can be used to replace steel structures. The facing layer may be fibrous material especially glass or carbon fibres, the facing material is preferably embedded into the epoxy matrix. Alternatively they may be matching box structures or concentric metal tubes. The sandwich structures may be prepared by laying up the fibre; coating and/or impregnating the layer with epoxy resin, laying a layer of heat activatable foamable epoxy material, providing a further layer of the fibrous material optionally coated and/or impregnated with epoxy resin on the foamable material and healing to foam and cure the epoxy materials. Alternatively they may be formed by extrusion of the foamable material between the surface layers.

Abstract: A fibrous structure having one or more vertically lapped layers having a first surface and a second surface and a facing layer secured to the first surface of the vertically lapped layer. The fibrous structure is adapted to be used in a flooring assembly. The fibrous structure may include a mesh and/or a backing layer on the second surface of a vertically lapped layer. The fibrous structure exhibits improved performance in below room testing and/or in-room testing as compared with traditional materials of the same thickness.

Abstract: Applying heat activatable adhesive to a substrate, the adhesive is solid at ambient temperature and can be melted at a temperature below its heat activation temperature wherein the adhesive formulation is supplied to a hot melt applicator where it is heated to above its melting point and below its activation temperature and the melt viscosity of the molten adhesive is controlled so that it can be ejected from the hot melt applicator onto a substrate to provide a coherent bead that adheres to the substrate and is dry to the touch on cooling and upon activation the adhesive is capable of expanding with a volume expansion greater than about 250%.

Abstract: A structural reinforcement for a vehicle comprising: a) a carrier having a base wall from which a plurality of projections extend, the plurality of projections including at least one first projection and at least one second projection and the at least one first projection having a height greater than a height of the at least one second projection; b) an activatable material which is heat activatable and affixed to the carrier, configured to secure the carrier in a cavity of the vehicle; wherein in event of an impact, the at least one first projection and second projection are configured to deform toward the base wall and/or in a direction of an impact load in response to the impact load; and the at least one first projection is configured to receive the impact load and deform before the at least one second projection receives the impact load and deforms.

Abstract: A structural reinforcement for insertion into a cavity of a vehicle structure including a base reinforcing portion, an expandable material and a localized reinforcement is disclosed. The localized reinforcement is placed within the structural reinforcement at a location of anticipated increased deformation during vehicle impact in an effort to reduce deformation and control the load distribution post-impact.
