Abstract

The application of fluoropolymers in highenergy-release pyrotechnic compositions is common in the space and defense areas. Pyrotechnic compositions of magnesium/Teflon/Viton are widely used in military flaresand pyrogen igniters for igniting the solid propellant of a rocket motor. Pyrotechnic components are considered highrisk products as they may cause catastrophic accidents if initiated or ignited inadvertently. To reduce the hazards involved in the handling, storage and transportation of these devices, the magnesium/Teflon/Viton composition was subjected to various sensitivity tests, DSC and had its stability and compatibility tested with other materials. This composition obtained satisfactory results in all the tests, which qualifies it as safe for production, handling, use, storage and transportation.

Author Biography

Luciana de Barros, Instituto de Aeronáutica e Espaço

Luciana de Barros was born on February 28, 1982. She graduated as a technician in chemistry at the Instituto Pentágono de Ensino in Santo André, São Paulo. She is a Chemical Engineer from the Universidade de São Paulo and is a pyrotechnic team member of the Instituto de Aeronáutcia e Espaço since 2004. She began working on her Master of Space Science and Technology in 2014, with the purpose to bring more knowledge and safety for the pyrotechnic field applied to space vehicles.
