The fracture degree shows a slight fluctuation around 1% at different temperatures, while the fracture complexity shows an increasing trend with the rise of temperature.

The sentences
The fracture fractal dimension showed a decreasing trend with the rise of temperature, which is rational because at a lower temperature, especially lower than the glass transition temperature of the binder, the brittleness of binder is enhanced, so more transgranular and trans-particle fracture will occur; while at a higher temperature, especially higher than the glass transition temperature of the binder, the viscosity of the binder is enhanced so more intergranular and inter-particle fracture will occur.
