Abstract
A pyrotechnic cutting device (14) is designed for directly cutting one or two parts (10) made form a nonmetallic material, such as a composite material. The device (14) comprises a pyrotechnic expansion tube (16), which acts on the part or parts (10) to be cut by means of a cutting member (32). This member can act in the manner of a punch or single or double shears. It can also be deformable or non-deformable. In the former case, the cutting member (32) can be integrated into the part (10) during its manufacture, particularly when said part is made from a composite material.
