摘要:
There is disclosed a method of applying activatable material to a member of an article of manufacture such as an automotive vehicle. According the method, the activatable material is provided to an applicator followed by applying the activatable material to the member. Preferably, the activatable material is applied in a condition that makes the material suitable for allowing further processing or assembly of the member, the article of manufacture or both.
摘要:
A member is balanced by determining a target location at which weight is needed to counter an imbalance. A weighted adhesive is applied to the target location to then balance the member.
摘要:
An energy management system and device for use in an automotive frame, rail, or other structural component of an automotive vehicle. The frame or rail having a cavity or exposed surface capable of supporting at least one member. The member having an interior portion and an exterior portion with the interior portion being defined by at least one trigger or step change to the geometry of the inner portion to target and direct axial bending of the system. A reinforcing material, such as a polymer-based expandable material, is disposed along the exterior portion of a member prior to final assembly of the vehicle by the vehicle manufacturer. The system is activated as the vehicle undergoes the final vehicle assembly process and paint operation which activates and transforms the reinforcing material to expand, bond and structurally adhere the frame rail to mange, direct, and/or absorb energy in the event of an impact to the vehicle from an applied load or an external force.
摘要:
A reinforced magnetic hot patch has an attached rigid backing. The hot patch expands and flows when heated to seal an opening in a structural member. A non-planar magnetic hot patch is also provided.
摘要:
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.
摘要:
An adhesive formulation comprising i) an adduct of an epoxy resin and an elastomer, ii) a phenoxy resin; a core/shell polymer; iv) a curing agent which provides a structural adhesive with improved low temperature impact strength particularly useful for bonding metal especially in the automotive industry.
摘要:
An epoxy/elastomer adduct, a method of forming the adduct and materials and articles incorporating the adduct are disclosed. The adduct preferably includes up to about 60% by weight of an elastomeric component, up to about 90% by weight of an epoxy component and optionally one or more additives.
摘要:
An automotive vehicle frame reinforcement system has a skeleton member designed to be secured to a vehicle frame, such as a roof or pillar section. An expandable material, such as an epoxy-based reinforcing foam, is disposed on the skeleton member. Once the system is attached to the frame, the foam expands and cures during an automobile assembly operation, bonding the reinforcement system to the frame. As a result, the reinforcement system provides enhanced load distribution over the vehicle frame without adding excessive weight.
摘要:
Methods and apparatuses are disclosed for applying melt flowable materials to components of articles of manufacture. The methods and apparatuses disclosed herein are concerned with formation of appropriate flowable materials, control over the manner in which the flowable materials are applied, treatment of the components prior to application of the flowable materials and the like. Moreover, the apparatuses and methods may be particularly suited for applying flowable materials to surfaces and components found in automotive, aerospace, and marine vehicles.
摘要:
A partition for forming a barrier in a channel has a molded resin-based plate and a plurality of thermally expandable pellets attached to one side of the plate. The partition is secured in place in the channel by mounting brackets. As heat is applied, a blowing agent in the pellets is activated and the pellets expand to many times their original volume. The resultant foam seals the gap between the plate and the surrounding structure and further secures the plate in place. The partition is particularly useful in forming a sound/water/air barrier in an automotive cavity.
