## Summary

Combining wood with another reinforcement creates a new material balance. A hybrid label is not evidence that the mixture captures every benefit of both ingredients without compromise.

## Technical context

Fibre identity, length distribution and orientation matter alongside the polymer and additives. Replacing a portion of wood changes the recipe and may affect processing. Comparisons should identify which quantities are held constant.

## What to measure and document

Define the intended benefit before choosing a hybrid. Compare controlled formulations at a consistent basis and measure relevant trade-offs. Document any additional handling and occupational controls required by the introduced reinforcement.

## Implications for development and specification

For product selection, require evidence for the actual hybrid profile and its connections. Do not transfer a result from a laboratory plaque to a commercial board with different geometry. Research novelty and suitability for an architect's project are separate questions.
