Mechanical part and method of manufacturing such a part

A mechanical part, comprising:

• at least two ends configured to hinge the part to other parts at each of the at least two ends;
• a central fiber preform of three-dimensional woven fabric configured to withstand compression forces to which the part is subjected in operation, said central fiber preform including an upper flange and a lower flange;
• and
• at least one peripheral fiber preform of three-dimensional woven fabric configured to withstand traction forces to which the part is subjected in operation,
• wherein said part is a lever of a landing gear brace,
• wherein at least a portion of the part includes composite material,
• wherein said at least one peripheral fiber preform surrounds said central preform so as to form two empty spaces at the respective ends of the part and between the central and peripheral preforms, said empty spaces configured to hinge to said other parts,
• wherein said at least one peripheral fiber preform abuts said upper flange and said lower flange of said central fiber perform, and
• wherein said at least one peripheral fiber preform includes at least one opening at one of the ends of the part, said at least one opening being contained within a lateral width thereof and forming a window to access a respective one of the empty spaces at the one of the ends of the part.
