Effects of Hybrid Fibre Reinforcement on Fire Resistance Performance and Char Morphology of Intumescent Coating

摘要: Recent researches of fire retardant intumescent coatings reinforced by single Rockwool and glass wool fibre at various weight percentages lengths showed some improvements to the mechanical properties char produced. Therefore, in this research fibres were combined together coating formulation several study their effects towards resistance performance morphology. The hybrid subjected two types tests; Bunsen burner 1000°C electric furnace 800°C for 1 hour, respectively. Steel temperature coated samples during test was recorded determine performance. Thermal stability chars determined Thermogravimetric Analysis (TGA). morphology then examined using Scanning Electron Microscopy (SEM) Energy Dispersive Spectrometry (EDS) conducted obtain elemental composition samples. This concluded that long-hybrid 12-mm length 0.6% fibre-weight produced top performing formulation. form survived elevated temperature, hence helped provide structure strengthen with highest steel 197°C.
