Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If triallyl isocyanurate (TAIC) or triallyl cyanurate (TAC) is used as a cross-linking agent, then thermal resistance and chemical resistance are improved, but fluidity deteriorates causing runback during impregnation
Solution Approach 1:
The patent modifies the molecular structure of the cross-linking agent by introducing a bulky substituent group at the 5-position of the isocyanurate ring. This structural parameter change reduces fluidity and prevents runback while maintaining the cross-linking functionality and thermal resistance properties of the TAIC/TAC compounds.
Solution Approach 2:
The invention creates a composite cross-linking agent that combines the reactive diallyl isocyanurate structure with a bulky substituent group. This composite structure integrates the beneficial cross-linking properties with the steric hindrance needed to control fluidity, achieving both thermal resistance and processability.
2Reliability
If TAIC or TAC monomers are used as cross-linking agents, then cross-linking efficiency is improved, but evaporation occurs causing environmental pollution and inconsistent laminate properties
Solution Approach 1:
The patent changes the volatility parameter of the cross-linking agent by introducing a bulky substituent group with higher boiling point. This reduces evaporation during the impregnation and hot-pressing processes, eliminating environmental pollution and ensuring consistent laminate properties while preserving cross-linking efficiency.
3Strength
If TAIC or TAC is used as cross-linking agent, then peel strength can be achieved, but processing stability deteriorates due to high fluidity
Solution Approach 1:
The patent modifies the viscosity and fluidity parameters of the cross-linking agent through structural modification. The bulky substituent group increases viscosity to prevent runback during processing, improving processing stability while the diallyl isocyanurate structure maintains cross-linking efficiency and peel strength.
4Ease of manufacture
If cross-linking agents with high fluidity are used, then impregnation can proceed, but runback occurs making mass production difficult
Solution Approach 1:
The patent optimizes the viscosity parameter of the cross-linking agent by introducing a bulky substituent group. This creates a balanced fluidity that allows complete impregnation of reinforcing materials while preventing runback, enabling stable mass production and continuous manufacturing processes.
