FAST-OPERATING ELECTRICAL INITIATOR HAVING A PLASTIC STRUCTURE AND GAS GENERATOR COMPRISING ONE SUCH INITIATOR

摘要

The invention relates to an electrical initiator with PTMSSUP®/SUP-type compressed pyrotechnic sheets, comprising a cap containing at least one pyrotechnic charge, a base and a resistive element. The invention is characterised in that the base is made from a composite material comprising a matrix that is formed from at least one plastic material having fibres dispersed therein, said composite material having a melting point varying between 260 and 320 °C and an axial thermal expansion coefficient of less than 30.10SUP-6/SUP KSUP-1/SUP in accordance with test ASTM E831. Optionally, the aforementioned cap can be made from the same material. The invention also relates to a gas generator comprising one such initiator.
