Abstract
The present invention relates to a connecting rod made of composite material, especially for internal-combustion engines, the composite material being formed by a reinforcement embedded in a cured material, and the connecting rod (A) comprising, along the longitudinal extension (X--X) of the connecting rod, a central shank (B) extended respectively, at its two ends, by a connecting-rod big end (C) and a connecting-rod small end (D). According to the invention, the connecting rod (A) is produced entirely as a single component made of composite material and the reinforcement of the composite material comprises superposed plies of crossed straight filling yarns, the filling yarns, which extend parallel to the longitudinal extension (X--X) of the connecting rod (A), constituting at least twice the volume percentage of the filling yarns which extend in each of the directions other than the longitudinal extension (X--X) of the connecting rod (A), and binding yarns pass through the superposed plies.
