However, one of the main limitations for the use of wood materials is its flammability.
The lowered flammability of wood materials enables them to be used in high-performance applications, which places emphasis on research into improving their fire retardant properties.
Experimental Materials.
After the main decomposition, mass losses of the residual materials of wood are found to be slow in the temperature range 353–410 °C (the third stage).

The nanosheet crystallites can be considered as a unique class of nanoscale materials, having an exceedingly high two-dimensionality with a molecular thickness ranging from 10nm-500nm [2-10].
Various new materials can be derived by using these nanosheets as building blocks [14].

Material Properties.
For strengthened beams, the groove was filled half way with epoxy, then the CFRP rod was placed inside the groove and epoxy was used to fill the groove to a height 5 mm away from the beam surface to give space for protective or decorative materials.
