Current research indicates that no single material is likely to provide the optimal solution under every condition.
However, several important questions remain unanswered.
Examples include:
- Which combinations of materials provide the greatest overall benefit?
- How do different materials interact over long operational periods?
- Which solutions provide the best balance between performance, durability and cost?
- Which materials remain environmentally sustainable throughout their lifecycle?
Material integration therefore remains an active engineering domain requiring continuous investigation.
