High Pressure Mixing Method (HPMM) for High Performance Epoxy Naoncomposites    

Increases the fracture toughness and water absorption resistance without altering the glass transition temperature.


Epoxy materials have industrial applications in various fields ranging from aeronautics, aerospace, automobile, sports equipment, adhesives and sealants, wood products, pipes, boats and reservoirs, trains, and even insulation resins for insulators in electrical lines.

Since most epoxy resins that are currently used are brittle, ongoing projects aim at enhancing the toughness of these materials as well as to improve their barrier resistance performance such as flammability resistance and water resistance. Enhancement in matrix fracture toughness, however, is usually at the expense of mechanical and thermal properties, such as stiffness, strength and glass transition temperature. Therefore, there is a need to develop new composites with higher fracture toughness without jeopardizing other equally important parameters.

The High Pressure Mixing Method (HPMM) indeed increases the fracture toughness and water absorption resistance without altering the glass transition temperature.
This technology entails a nanoclay dispersing technique whereby the novelty resides in the utilization of mechanical shear force together with collision against obstacles and cavitation to produce instability in the clay aggregates thereby resulting in enhanced exfoliation.

Primary Application of the Technology

Used for nanocomposite materials, adhesives, sealants amongst numerous other applications. These materials are in turn used by manufacturers of aircrafts, automobiles, sports equipment, and components for pipes, boats, reservoirs, etc.

Competitive Advantage

 Higher modulus
 Increased fracture toughness
 Decreased gas permeability and flammability
 Exceptional temporal stability of composite mixture before the curing process
 Competitive price
 Fulfills all industrial, environmental and regulatory requirements

Comments on Deal Structure, Potential Terms and Restrictions

Ideally looking for strategic partnership with resin producers for making composite materials.

The seller may consider selling these patents individually.

Additional Information

High temperature resins used in aerospace have been tested with the HPMM and have shown fracture toughness enhancement of 560%. Scaling for industrial production has also been successfully studied.

Class 523: Synthetic Resins Or Natural Rubbers -- Part Of The Class 520 Series

Part of the Class 520 Series - some general types of subject matter include: Solid synthetic resins, per se, regardless of utility; processes of preparing a synthetic resin involving a chemical reaction; reactable compositions which form a product; processes of purifying a solid synthetic resin or composition containing a synthetic resin by a chemical or physical process; process of reclaiming or recovering a solid synthetic resin; processes of treating a synthetic resin or specified intermediate condensation product with a reactant, or product thereof; blends of solid synthetic resins, processes of preparing or treating such blends; chemically reacted solid synthetic resins or processes of preparing; potentially reactable compositions which contain a solid synthetic resin or SICP and products of such a reaction, or processes of preparing; room vulcanizable potentially reactive compositions which merely require moisture and which are usually activated by heat and/or pressure to form a product; compositions of a nonreactant material and a solid synthetic resin or SICP; compositions containing a structurally defined material which is dispersed in a matrix which is not identified by overall dimension or some structure or processes of preparing; single-layered products containing a solid synthetic resin or composition thereof reciting no structure or dimension, or a fiber, filament, etc., which is no more than the material from which it is made, nonstructured single-layered web or sheet is encompassed; particles or a powder, per se, of a solid synthetic resin or composition thereof for which particles or powder no dimensions are recited; reactable compositions which form a product proper for this class and contain a photoinitiator or photosensitizer which are activated by wave energy or processes of preparing.

Subclass 440: Designated nonreactive material (DNRM) has numerically specified characteristics, e.g., particle size, density, etc., other than viscosity, m.p., b.p., molec. wt., chemical composition or percentage range
Subclass 443: Silicon
Subclass 466: Inorganic SI-O bond DNRM

Class 366: Agitating

Apparatus for, and corresponding methods of operating on fluid, viscous, plastic, or fluent particulate material solely for causing portions of the material to move irregularly with respect to each other so as to intermix. The material may be in motion or at rest immediately before agitation.
