Rod, method for manufacturing same and aircraft floor structure including same

Abstract

The present invention relates to a rod, an aircraft floor structure including same and a method for manufacturing said rod. The invention applies to a rod adapted to absorb mostly axial stress, in particular in the field of aeronautics. Said rod (101) includes a tubular body (102) having two ends with two heads (103) for connecting the ends to adjacent structures and which is adapted to absorb mostly axial forces, each head including a tip (105) which is widens towards the body and is adhered to the same via an adhesive interface (111). According to the invention, the rod includes at least one first seal (110) mounted radially between and against the body and the tip of each head, and axially towards the inside of the adhesive interface. The rod can be manufactured by mounting the first seal in contact with each tip and a first inner or outer surface of an end area opposite the body, and then by adhering each tip to the body by injection and suction of an adhesive (111) radially between the body and each tip and axially towards the outside of the first seal.

Description

technical field [0001] The invention relates to a connecting rod, an aviation floor structure incorporating it and a method for manufacturing the connecting rod. The invention applies generally to connecting rods adapted to primarily act on axial forces, in particular (but not exclusively) in the aerospace sector, which are advantageously configurable and can be made of composite materials. Background technique [0002] Existing composite linkages intended to act on axial forces generally have an elongated shape provided with a central body with flared end pieces at both ends for connection to structures, especially for generating traction-compression forces The ends of the ends are terminated, and the connection is usually completed by utilizing the respective connection axis of these end installations. [0003] Document WO-A1-2010 / 024994 describes a connecting rod whose composite body is assembled by adhering to its end pieces connected to the head, the body ends covered ...

AI Technical Summary

Problems solved by technology

[0004] The connecting rods described in this document have the disadvantages of relatively high quality and high manufacturing costs, not least due to the inserts required for their assembly

[0005] More generally, one of the main disadvantages of composite connecting rods known at this time is their high quality, which on the one hand is related to the process method used, usually resin transfer molding (RTM) or pre-preg compression molding using bladders, on the other hand In relation to the strengthening of these connecting rods, said strengthening is used to give them sufficient strength against impacts and any manufacturing defects, as tolerance to damage and manufacturing defects is a clearly desired characteristic of composite parts
