Abstract: An acoustic composite comprising a plurality of discrete air flow resistive layers layered on top of each other including a top layer and one or more lofted fibrous layers produced by a lapping process, the top layer having a specific air flow resistance that is greater than a specific air flow resistance of the one or more lofted fibrous layer.

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.

Abstract: A solid, dry to the touch at ambient temperature, heat curable, generally non-foaming structural adhesive that exhibits shape memory characteristics. The adhesive can be cured at an elevated temperature and contains a high molecular weight polymeric constituent that can be oriented such that at an elevated temperature below the curing temperature the material will shrink in one plane while increasing its thickness at a temperature in the range of from above the elevated temperature to below the curing temperature.

Abstract: An improved approach toward the electrostatic deposition of activatable adhesive formulations is disclosed. The activatable adhesive formulations are formed for transforming from a dry powder precursor layer to a precursor layer film.

Abstract: A thermohardenable structural adhesive material that upon curing has an elongation at break of at least 10% and has a glass transition temperature (Tg) of 80° C. or higher and is useful as a structural adhesive in automobiles to reduce the deformation of bonds particularly during accidents, the adhesive is dry to the touch at ambient temperature and can be melt processed at temperature below that at which thermohardening occurs. The adhesives are useful in applications requiring a combination of high strain to failure, glass transition temperature more than 80° C., high stiffness and high strength. This combination is of particular interest in the aerospace and automotive industries.

Abstract: A solid dry to the touch at ambient temperature structural adhesive which can be cured at elevated temperature and which can be molded at an intermediate temperature is provided as well as the use of the adhesive for bonding metals.

Abstract: Flexible films of thermosetting adhesive materials which are non-tacky to the touch are storage stable at room temperature and can be cured at elevated temperature with a short cure time and can be cured to produce a tough flexible adhesive layer including bonding to oily surfaces, the materials are particularly useful in bonding together dissimilar substrates.

Abstract: A heat exchanger may include at least one fluid passageway adjacent a heat transfer plate and a plurality of heat transfer elements positioned in the at least one fluid passageway and joined with the heat transfer plate. The heat transfer elements may be positioned with first spacings therebetween at an inlet end of the at least one fluid passageway. The heat transfer elements may be positioned with second spacings therebetween at an outlet end of the at least one fluid passageway. The first spacings may be smaller than the second spacings.
