A Study of Metal-Ceramic Composite Foams Combustibility

This paper presents a study of the non-combustibility of cast metal-ceramic composite foams, specified in PN-EN ISO 1182: 2010 (Reaction to fire tests for products - Non-combustibility test). It was explained why foams with AlSi11 warp and SiC reinforcement are non-flammable. The paper describes relationship between the compressive stress values and compression strain values for three foams - aluminium foam, AlSi11/SiC composite foam, not subjected to flammability test, and AlSi11/SiC composite foam, subjected to flammability test. No difference between strength of combustible and incombustible foams was found. This study aims to determine the fire-fighting features of the materials described herein, which can be used, among many, in naval industry.
