Abrégé

The invention relates to an energy absorption buffer comprising a hollow part (52, 54) constructed of a composite material and extending in a longitudinal direction, said composite material comprising a matrix made of thermoplastic material and a fibrous strengthening material embedded into said matrix made of thermoplastic material, said hollow part (52, 54) being able to compress irreversibly in said longitudinal direction in order to absorb the impact energy. Said fibrous strengthening material is a textile material having slivers of fibres that extend in the three spatial directions.

Abrégé

The invention relates to a method and device for tightening a screwed assembly. The tightening device comprises: drive means (44) intended to turn a nut (32), and measurement means (48) for measuring the couple of the forces (torque) used in tightening the nut (32) in relation to a threaded rod, in order to be able to reach a limit torque value (CSI) corresponding to a given axial tension (Fv) on said threaded rod. According to the invention, the device comprises: a specific elastic element (34) intended to be deformed when the nut (32) is turned with respect to the threaded rod (26); recording means (50) for simultaneously recording the amplitude of the angle through which the nut (32) is turned and the magnitude of the tightening torque; and calculation means (54) for calculating the aforementioned limit tightening torque (CSI) during tightening.

Abrégé

The present invention relates to a device for the reversible assembly of two parts (2 and 3). Said device is characterized in that it consists of at least one means (1) having at least one active region incorporating a composite material with a continuous and controlled deformation under the effect of an adjustable temperature variation of at least one active layer of said composite material and inducing, in each region of said means (1) having such an active region, a deformation of corresponding direction and corresponding amplitude that results in the two parts (2 and 3) being secured together or disengaged from one another.
