Mike got it right. Phenol-formaldehyde resin, binding any number of filler materials, linen, paper, cotton, and glass. Phenol is the part that smells like (old fashioned) Lysol or Lifebuoy soap.
I'd worry more about the glass dust than the resin -- yes, phenol and formaldehyde are toxic, but the glass can do a major number on your lungs. Positive ventilation is the best route.
And glass-filled Micarta will chew up HSS tools. Better to use carbide if you're working a lot of it.
