Sorry what do you mean?
The famous 'hockey stick' curve - rise in CO2/temperature levels and climate change
or the material that a hockey stick is made from?

Think in terms of spring stiffness - theres probably lots of papers/research on baseball bats = same principle.

Coefficient of restitution of the stick is higher for composites. They also tend to be stiffer. you are unlikely to find any exact compositions or manufacturing data for real sticks as companies keep that to themselves.

Also just to clarify are you taling about field or ice hockey?.

You dont need to read all of it just look for the power equation. That'll give you all the terms that count.
