Embodiment Construction

[0061] The invention relates to a method of producing a substantially circular or preferably oval annular frame 10 made of composite material, said frame 10 being shown in FIG. 1 .

[0062] Preferably, the annular frame 10 obtained by carrying out the various steps of the method is configured as a fuselage equipped with an aircraft engine, still more particularly an aircraft, which in turn can advantageously be made of composite material.

[0063] refer to Figure 2A and 2B , in a first step of the method at least one tubular casing 9 of fibers of sleeve type is slid onto an assembly 8 preferably of uniform cylindrical shape and comprising at least two subassemblies 81 , 82 .

[0064] Said tubular casing 9 is advantageously composed of braided fibers, for example made of glass, polyamide or preferably carbon, either dry or pre-impregnated with polymer resin.

[0065] A tubular casing 9 made of braided carbon is particularly advantageous because the braid has controllable def...

Abstract

A method for manufacturing an annular frame made of composite material comprises the following steps: - at least two coaxial subassemblies (81) comprising at least two coaxial subassemblies (81) movable axially relative to each other , 82) slide at least one tubular housing of dry fibers (9), said grooves being arranged in the general plane of said frame; said groove (11) between the two subassemblies (81,82) and tighten said two subassemblies (81,82) so as to hold said portion (90) of the tubular housing (9) in said groove In (11); - couple the two parts (91, 92) of the housing (9) outside the slot (11) and fold the resulting coupling (93) to said two subassemblies (81, 82) on one of them to obtain a preform (15) of dry fibers; said preform (15) is solidified by polymerization.

Description

technical field [0001] The invention relates to the field of components made of composite materials comprising a reinforcement based on dry or pre-impregnated fibers in a synthetic resin matrix. Background technique [0002] The invention will be applied primarily in the field of manufacturing composite ring frames, in particular frames for portholes configured, for example, to equip fuselages of aircraft and especially aircraft, which fuselages are generally also made of composite material. [0003] Aircraft portal frames traditionally have a circular or preferably elliptical shape and said frames are not contained in a single plane; they are curved so that they can be optimally adapted to the cylindrical shape of the equipment fuselage. [0004] Porthole frames, especially in aircraft, must fulfill several functions. [0005] In one aspect, the porthole frame is configured to be secured to the equipment body and in turn allows the door opening to be secured via the gasket...
