Influence of Carbon Fiber on Burning Rate and Infrared Radiation Intensity of Mg/PTFE Infrared Composition

The influence of burning rate on the infrared radiation intensity of Mg/PTFE infrared composition was studied.The burning rate,infrared radiation intensity and quality radiation energy for Mg/PTFE infrared composition of different ratios were measured and calculated,it was obtained that the infrared radiation intensity is the largest when the ratio of Mg and PTFE is 50∶50.The different content of carbon fiber was added to Mg/PTFE composition,and the burning rate and infrared radiation intensity increase along with the content of carbon fiber increases.It was defined that the more the content of carbon fiber,the larger the thermal diffusion coefficient of composition,and than the burning rate is speeded up,the infrared radiation intensity increases by analysis.
