Introduction

The carbon-ceramic PIP sintering furnace developed by Yuanhang Industrial Furnace is a new type of ultra-high temperature equipment, primarily used for the sintering and preparation of carbon-ceramic composites and carbon/carbon composites.

PIP Method (Polymer Infiltration and Pyrolysis): An organic polymer precursor is dissolved or melted, then impregnated into the fiber preform under vacuum or pressure. After drying and solidification, high-temperature sintering pyrolysis is performed. This process offers significant advantages, including relatively low preparation temperatures, the ability to form complex large-scale components, and excellent material properties.
