Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for improving the physical, chemical, and structural properties of materials, such as polymer composites, often require the addition of reinforcement particles, which complicates the manufacturing process and increases costs. Additionally, these methods struggle to achieve high enough shear rates and hydrostatic pressures to fully delaminate or disentangle reinforcement particles like graphene or carbon nanotubes.
Innovation Solution
A system and method that utilize upper kinematic pairs with mechanical elements in contact with a material in a fluid state, applying high relative velocities and contact pressures to generate extremely high hydrodynamic pressures and shear rates, effectively delaminating, disentangling, and fragmenting particles without the need for reinforcement particles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If reinforcement particles are added to improve material properties, then physical and structural properties are improved, but manufacturing complexity and production costs increase
Solution Approach 1:
The invention extracts and eliminates the reinforcement particles from the composite material system, treating only the matrix material with high shear rates and hydrostatic pressures. This removes the need for adding separate reinforcement components while still achieving improved material properties through direct modification of the matrix material structure.
Solution Approach 2:
The invention applies extreme parameter conditions (high shear rates up to 10^9 s^-1 and hydrostatic pressures up to 6 GPa) to the matrix material to fundamentally change its physical and structural properties. These parameter changes enable the matrix material itself to achieve enhanced strength and performance characteristics without requiring reinforcement particles.
2Ease of manufacture
If conventional mixing methods are used, then manufacturing process is simple, but shear rates and hydrostatic pressures are insufficient to delaminate or disentangle reinforcement particles
Solution Approach 1:
The invention replaces conventional mechanical mixing systems with a high-pressure homogenization system that generates extreme shear rates and hydrostatic pressures. This substitution enables complete delamination and disentanglement of reinforcement particles (when used) or fundamental restructuring of the matrix material, achieving manufacturing precision that conventional methods cannot attain.
Solution Approach 2:
The invention dramatically changes the operating parameters from conventional mixing conditions to extreme conditions with shear rates up to 10^9 s^-1 and hydrostatic pressures up to 6 GPa. These parameter changes enable complete delamination of stacked sheets and full disentanglement of linear nanoparticles, achieving the manufacturing precision required for high-performance composites.
3Manufacturing precision
If high shear rates and hydrostatic pressures are applied to delaminate reinforcement particles, then particle dispersion quality improves, but the need for reinforcement particles increases production costs
Solution Approach 1:
The invention extracts and eliminates the reinforcement particles from the system, applying the high shear rates and hydrostatic pressures directly to the matrix material. This achieves the desired dispersion quality and structural improvement without the need to purchase and process expensive reinforcement particles like carbon nanotubes or graphene.
Solution Approach 2:
The invention enables the matrix material to self-organize and self-structure under extreme shear rates and hydrostatic pressures, creating improved physical and structural properties intrinsically. The material serves itself to achieve the enhancement that would otherwise require expensive reinforcement particles, eliminating the need for external reinforcement additives.
