Definitions
- the present patent application relates to the field of the fa b io n d e p e cies e n m ate ri a u x com posites, in particular for aeronautics.
- pre-impregnated plies of resin can be used, or resin transfer methods can be used.
- RTM Resin Transfer Molding
- This technique consists in placing a preform constituted by a ply assembly inside an enclosed mold, in which resin is injected under pressure. This resin thus progresses through the folds, and gradually fills all the gaps available. Once this filling is completed, the temperature of the mold is raised so as to harden the resin.
- T-pieces that is to say pieces comprising two sections 1, 2 substantially perpendicular to each other, as can be seen in FIGS. 1 and 2 below. attached.
- Such parts can be used especially for the manufacture of beams.
- a substantially plane stack A a substantially plane stack A
- two stacks substantially L, B and C the latter two being joined so as to define the foot of the T.
- This resin mass devoid of fibers, is a weak point of the part obtained in fine: it can indeed be at the origin of a delamination of the surrounding folds, and limits the resistance to tensile stresses tending to separate the stacks B and C of the stack A (arrow 5 in FIGS. 1 and 2).
- the first solution is to pre-fill the junction area of the three stacks of a set of fibers held together: this solution, called “nail head" with respect to the shape of the cross section of said junction area , causes many difficulties in the context of an industrial process.
- the added fibers can move during the resin injection, and finally occupy positions that are not optimal with respect to resistance to external forces.
- the second solution is to sew between them the stacks A, B, C in their junction area, as can be seen in Figure 2 (stitches 7).
- This solution has the disadvantage of being able to be implemented only before introduction of the preform constituted by the stacks A, B, C on the RTM mold, the latter comprising in particular two metal cores preventing passage of the needles. sewing at the appropriate places.
- this seaming solution in practice makes it possible to increase only slightly the resistance to tensile stresses tending to separate the stacks B and C from the stack A.
- the present invention is thus particularly intended to provide a method of manufacturing a composite T-piece by resin transfer molding, that it is easily industrial isable and has a resistance improved vis-à-vis efforts to separate the two sides of the T from each other.
- This object of the invention is achieved with a method of manufacturing a T composite part by resin transfer molding, comprising the steps of:
- the orientation of the fibers forming the loops perpendicularly to the fold plane stack, and the passage of these fibers in the parts of the L-shaped stack of folds which are substantially perpendicular to the fold plane stack is that is, in fact in the foot of the T, offers a particularly remarkable resistance with respect to the efforts that tend to pull the L-shaped stacks of the plane stack.
- said flat stack and said L-shaped stacks are assembled prior to the introduction of the preform between the two cores of the molding tool;
- said L-shaped stacks are assembled, introduced between the two cores of the molding tool, and covered with said plane stack;
- first and a second group of loops are formed, the length and inclination of said first group of loops with respect to the direction perpendicular to said plane stack being greater than those of said second group of loops.
- the present invention also relates to a composite part obtained from the aforementioned method.
- FIG. 1 is a cross-sectional view of a composite part of the prior art, as described in the preamble of the present description,
- FIG. 2 is a perspective view of this same piece
- FIG. 3 is a sectional view of a composite part during manufacture with the process of the present invention
- FIG. 4 is a cross-sectional view of this part once manufactured.
- FIG. 5 is a cross-sectional view of another part manufactured with the method according to the invention.
- identical or similar references denote identical or similar members or sets of members.
- the parts of the stack of folds L, B and C which are substantially perpendicular to the stack of folds A, are placed between the two metal cores M1 and M2 of the molding apparatus M.
- fold plane stack A can be assembled to the two stack of L, B and C folds prior to the introduction of the preform thus formed between the two cores M1 and M2.
- these fibers are brought inside the plane stack of folds A from the free face 11 of the latter, the fiber is penetrated inside the respective part 81, 82 of each stack of folds L, B and C, the loop b is made inside this part, then the fiber is removed by the free face 1 1 of the stacking fold plane A, near the entry point of this fiber in this stack.
- the general direction of the fiber, outside the loop B, is substantially perpendicular to the plane stack A, as can be seen in FIG. This operation is repeated as many times as necessary, so as to obtain a plurality of fibers each defining loops b1, b2, b3 formed inside the portions 81 and 82 of the L, B and C stacks. fibers having a general direction substantially perpendicular to the plane stack A.
- This resin will in particular be positioned around the fibers forming the loops b1, b2, b3.
- the molding tool M is subjected to a rise in temperature, allowing the rapid polymerization of this resin.
- the fibers forming the loops b1, b2, b3 make it possible to achieve a very strong reinforcement of the junction zone of the three stackings of folds A, B, C.
- these fibers make it possible to obtain excellent tearing resistance of the L, B and C folds with respect to the stack of A folds.
- these loops can be made with carbon wire, and be spaced at a pitch of 3 mm from each other, penetrating to about fifty millimeters inside the parts 81 and 82 of the Stacking of folds in L, B and C.
- the folds forming the stacks A, B and C may be formed of satin carbon.
- the stack A may comprise for example 20 plies, and the stacks B and C 5 folds each.
- FIG. 5 shows an embodiment in which the junction between the stackings of folds A, B, C is further reinforced compared with the embodiment of FIG. 4.
- a first group of loops b1, b2, b3 and a second group of loops b4, b5 are provided, the length 11 and the inclination a1 of the first group of loops b1, b2, b3 relative to one another. at the perpendicular direction P to the plane stack A being greater than those 12, a2 of the second group of loops b4, b5.
