ASSEMBLY HAVING TEMPERATURE-DEPENDENT SELF-TIGHTENING CONNECTION Russian patent published in 2018 - IPC F16B19/05 F16B19/10 

FIELD: machine building.

SUBSTANCE: invention relates to assembly (100) comprising first and second parts (10, 20) made of composite material and are held against one another by at least one fastening system (50) comprising rivet (30) that has countersunk head (31), from which there extends shank (32) that has widened end (320) and washer (40) that engages with widened end (320) of shank (32) of rivet (30), wherein head (31) of rivet (30) bears against countersunk hole (12) made in first part (10), said washer (40) bearing against second part (20). Washer (40) has, on its surface (43) further from its surface (42) bearing against second part (20), portion (430) with a conical shape. Washer (40) also has central countersunk hole (410) on the surface of which widened end (320) of shank (32) of rivet (30) rests.

EFFECT: invention aims to propose a solution for the assembly of parts made of composite material using one or more fastening systems that have a higher coefficient of thermal expansion to the coefficient of thermal expansion of the composite material parts, the fastening system at little or no impact on the aerodynamic performance of the assembly.
