For pre-cast concrete, ready mix concrete and monolithic refractories fibers provide an excellent secondary reinforcing result for plastic-shrinkage, crack control and increased impact resistance.
Polyester and Nylon fibers are commonly used in refractory for investment casting slurries. The addition of fiber to the slurry provides reinforcement in the shell construction by adding permeability during shell firing.
Synthetic fiber flocks such as Nylon and Polyester, are used in thermoplastic polymer applications and Natural fibers such as Cotton & Cellulose in thermosetting polymers, The synthetic -fibers are also used for the construction of modeling clays for improved performance during firing.
