LASER TREATED HYBRID COMPOSITE MATERIAL FOR FIRE RESISTANCE APPLICATIONS

HYBRID COMPOSITE MATERIAL IS PREPARED FOR FIRE RESISTANCE PURPOSES, THE MATERIAL DECREASE FIRE RATE AND ELIMINATE MECHANICAL FAILURE. SOME HIGH MELTING POINT COMPOUNDS AND OXIDES ARE MIXED WITH SHORT FIBERS AND FABRICATED. EASY FABRICATION OF THE HYBRID COMPOSITE TO INTRICATE SHAPES IS ACHIEVED BY THE TRANSFORMATION OF THERMOPLASTIC TO THERMOSET. THE PROCESS IS DONE BY BOTH LASER AND CHEMICAL TREATMENT. THE DIFFERENT COMPOUNDS ABSORB THE LASER BEAM AND A SIGNIFICANT IMPROVEMENT IN THE MECHANICAL PROPERTIES IS RECORDED DUE TO CROSS LINKING
