Hi everyone,

I would like to know which of these combinations is correct.

reinforcing materials or reinforcement materials

A friend and I were discussing this and it concerns flexible supportive/strengthening materials, for example, used in shoes .
With this hint what would you consider to be correct?
I know my choice, what is yours and why.

Neither are incorrect. Reason: you can use either and still make sense.
