Unsaturated polyester(UP) inhibitor has many advantages and has been widely used in many rocket motors and gas generators,but it also has the disadvantage of high ablation rate.

The results of line ablation rate,scanning electron microscope and thermal analysis showed that the type of polyorganosiloxane affected the ablative properties of silicone rubber most;the ablative properties of phenyl silicone rubber was superior to that of vinyl silicone rubber.

The effect of varying the content of PSA pulp in the silicone rubber on its dispersion was analyzed,as well as the effect on the tensile strength,elongation at break,ablation rate and hardness of the resulting composite.

Some calculations and analysis for three examples under different ablation rates were demonstrated.

The effects of the respective content of silica aerogel and boron-phenolic resin on the properties of EPDM/NBR flexible insulation material,such as tensile strength,elongation-to-break,mass ablation rate,linear ablation rate and relative density were analyzed and compared.

The mechanical properties,linear ablative rate,smoke production and density of the EPDM/OPS heat insulation materials were determined.

Effect of laser parameters on mass ablative rate of carbon fiber reinforced composite;

The results indicate that the composite ablative mass is directly proportional to the laser radiation energy when the laser radiation intensity is greater than 10 kW/cm2;with the same laser energy radiation,the mass ablative rate at high intensity of 0.

An artificial neural network (ANN) model for research of the burning rate of modified carbon/carbon composites (C/C composites) is developed by using back propagation (BP) algorithm.
