Paragraph starter

The research by Zhang (2009) demonstrates that the nanoscale dispersion of silicate platelets within a polymer matrix significantly enhances fire resistance by promoting the formation of a stable char layer. This char acts as a barrier, shielding the underlying material from heat and preventing the release of flammable gases, thereby reducing the overall flammability of the composite.
