Adding wool to cob mixture?

Anyone have experience, opinions or advice about adding wool fiber (from cleaned sheep’s fleece) to cob mixture for walls in a small building?

Thanks!

Opinion:

It sounds like a great idea to incorporate wool, as long as it's carded and spread evenly throughout the mix.
The idea is not unlike tried and true technology, like horsehair plaster, reinforced concrete, or modern resin composites (laminated carbonfiber/fiberglass in resin).

You create the composite by combining a strong but brittle material (plaster, resin, etc.) with a flexible fiber that can bind across multiple fragments if/when there are microfractures. This holds it all together.

I have never heard of it, and would not like to say it will not work.
- It may be hard to mix in
- cob gets its strength from its size
- would you cut the wool into short lengths?

From; wool into concrete

The inclusion of sheep wool fibers to concrete mixes decreased the compressive strength. However, the addition of sheep wool fibers subsequently improved the tensile and flexural strength values of concrete, thereby improving the concrete ductility with higher energy absorption capacity. The microstructural characteristics of sheep wool fiber reinforced concrete were conformed to have good bonding and low voids. The findings of the study revealed that the addition of sheep wool fibers in the production of concrete is viable both technically and environmentally.
