The hardness is read directly from the dial with either the R, L, M, E or K scales. The higher the number in each scale, the harder the material. R and M scales are commonly used with plastics. All it depends upon which polymer you use to make composite.

I believe measuring hRc may not be very useful to you. Further which type of reinforcement did you use (i.e. Fibre or what?) rather you may try testing strength and stiffness

Pawan Sharma

Rockwell Hardness Test of FRP Composites are performed on R and M Scale depend on the type of material, i.e. thermoplastic or thermosetting. For Thermosetting M scale and for thermoplastic R scale is used.
