Abstract

In this work, we investigated the possibility of improving the flexibility of sealing heat-insulating materials by introducing a reinforcing component into the composition of the material in the form of chopped oxide ceramic refractory fibers. The effect of a reinforcing component on the change in the critical bending radius of samples of fibrous material based on ceramic refractory fibers has been studied. Sample tests showed an improvement in flexibility by 12–25 %, depending on the thickness and bulk density of heat-insulating materials.
