Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thermosetting resin compositions do not adequately form cured products with high enough toughness for applications requiring enhanced mechanical strength.
Innovation Solution
A thermosetting resin composition containing a first resin and resin particles with an amide bond, featuring specific functional groups and viscosity ranges, is used to enhance the toughness of the cured product.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If an epoxy resin composition containing resin particles with polyamide resin is used to increase toughness, then the toughness of the cured product is improved, but the mechanical strength and overall performance remain insufficient for high-demanding applications
Solution Approach 1:
The patent applies parameter changes by precisely controlling the second functional group content (25-190 mmol/kg) and relative viscosity (1.50-2.50) of the second resin. These parameter optimizations enable the resin particles to form stronger interfacial bonds with the first resin, significantly improving both toughness and mechanical strength simultaneously
Solution Approach 2:
The patent uses composite materials by combining the first thermosetting resin with resin particles containing the second resin having amide bonds and specific functional groups. This composite structure creates a synergistic effect where the interface between the two materials is strengthened through chemical bonding, resulting in enhanced overall mechanical properties
