1. A downhole hydraulic frac tool for use in a hydraulic fracturing system, the frac tool comprising:
a dissolvable frac tool member that includes a water-dissolvable composition, the composition including:
a water-soluble thermoplastic polymer; and
water-soluble bulk metallic glass (BMG) particles, wherein:
the BMG particles are embedded within a matrix of the water-soluble thermoplastic polymer,
the BMG particles have a greater tensile strength than a tensile strength the water-soluble thermoplastic polymer,
the BMG particles have a higher fracture toughness than a fracture toughness the water-soluble thermoplastic polymer, and
the BMG particles have an average size in a range of 50 to 100 nm.
