Benefits of technology

This patent describes a method for making a structure using a reinforced thermoplastic material formed by reacting an epoxy and an amine. The structure has a random orientation of fibers, which increases its strength. The method involves heating and deforming the structure to a desired shape, and then joining it to a secondary component using heat and pressure. The secondary component can be a conductive component. The structure can be installed in a vehicle after it has been treated in a paint bake oven. The technical effects of this patent are improved strength and flexibility of the structure, as well as increased viscosity and better bonding with the secondary component.

Problems solved by technology

As a result, there is a potential for the weakening of structures, and the consequent need for stiffening or other structural reinforcement.

Abstract

A structural reinforcement for an article including a carrier (10) that includes: (i) a mass of polymeric material (12) having an outer surface; and (ii) at least one fibrous composite insert (14) or overlay (980) having an outer surface and including at least one elongated fiber arrangement (e.g., having a plurality of ordered fibers). The fibrous insert (14) or overlay (960) is envisioned to adjoin the mass of the polymeric material in a predetermined location for carrying a predetermined load that is subjected upon the predetermined location (thereby effectively providing localized reinforcement to that predetermined location). The fibrous insert (14) or overlay (960) and the mass of polymeric material (12) are of compatible materials, structures or both, for allowing the fibrous insert or overlay to be at least partially joined to the mass of the polymeric material. Disposed upon at least a portion of the carrier (10) may be a mass of activatable material (128). The fibrous insert (14) or overlay (960) may include a polymeric matrix that includes a thermoplastic epoxy.

Description

TECHNICAL FIELD[0001]The present invention relates generally to composite materials, particularly to composites having a thermoplastic epoxy polymer phase, which can be employed in a number of applications, such as in structural reinforcements and / or baffles for use in transportation vehicles.BACKGROUND[0002]There is an ongoing effort in many industries to lighten the weight of articles. In many instances, this is achieved by the selection of materials that have a lower density, thinner section thicknesses or both, as compared with prior materials or structures. As a result, there is a potential for the weakening of structures, and the consequent need for stiffening or other structural reinforcement.[0003]In the field of automotive vehicle manufacturing it is common to employ structural reinforcements within cavities of the vehicle body structure. For instance, it has become common to employ within a cavity of the vehicle body structure a relatively rigid molded polymeric carrier th...
