Definitions
- the present invention relates generally to the field of shipbuilding. It relates more particularly to a method for manufacturing reinforced / stiffened plates by stiffening elements comprising laminated composite materials and the plate obtained by the method.
- the reinforced plates are intended for the realization of vessel walls. More specifically, the invention relates to a method of stiffening plates for producing vessel walls and comprising laminated composite materials.
- the flat areas must be reinforced or stiffened / stiffened, these terms being considered equivalent in the context of the invention, to withstand the stresses experienced by the ship.
- This also applies to interior partitions which are preferably made of relatively light materials, especially composite materials, in order to reduce the weight of the ship.
- the internal partition walls in particular those consisting of separating plates between two levels of the ship (typically the floors and bridges), must more particularly be reinforced because they are substantially horizontal and loads and constraints that they undergo and which are essentially applied along a perpendicular to the surface of the panel constituting the plate.
- stiffening elements on the underside of the panel of the plate.
- a network of stiffeners comprising foam or wood forms that are covered with one or more layers of fiber / resin composite is manufactured on site directly on the panel itself. These layers come back extra thickness on the panel to stiffen, on either side of the base of the foam or wood form.
- This "made-to-measure" method is relatively long and tedious because you have to install shapes on the panel and then cover them with composite.
- this method leads to leaving in the plate foreign materials to those of the composite consisting of layers of fibers and resin.
- Aircraft in the field of aviation are known for reinforcing walls by US-4,786,343, US-2012/282441 and US-2007/277470.
- the reinforced plate produced no longer includes the "foreign" materials which served as a form in the traditional method described above and which do not participate in the mechanical strength of the assembly. It is therefore possible to make reinforced sheets of composite material consisting exclusively of stacks of resin-impregnated fiber plies and therefore without any "foreign" material which would only be there to give the stiffener shape.
- the invention relates to a method of stiffening plates for the production of vessel walls and comprising laminated composite materials, the laminated composite materials being constituted by stacks of resin impregnated fiber webs.
- At least one elongated profile made of laminated composite material having a cross-section of a shape determined along its length is manufactured beforehand, the profile produced beforehand and obtained being rigid because of the polymerization / solidification of the resin having impregnated the layers fibers that the profile has, and, on the other hand, it implements a panel having two main faces and having at least on the surface of at least one of its two main faces a laminated composite material, the resin having impregnated the sheets of fibers that comprises the panel being polymerized / solidified, and
- said at least one profile made beforehand is assembled and fastened together on one of the main faces of said panel, the main face of the panel receiving the profile comprising laminated composite material, and the profile manufactured beforehand has a cross section of determined shape which comprises three parts. in continuity: two soles and a core, the two soles and the core being substantially straight in cross section of the profile, the core being connected to the soles along its two opposite lateral edges, and the two soles and the core are extended longitudinally in three distinct planes, the plane on which extends the soul crossing the two separate planes on which the soles extend, the two planes on which extend the two soles being parallel to each other and crossing the plane on which extends the core with an angle of about 90 °, each sole having two main faces, a main inner side side of the core and a free external main face opposite to the previous one, one of the two soles of the profile made beforehand being applied by its free external main face on the panel.
- a preformed section is used, the two soles of which are on the same lateral side of the core, the cross section of the section being U-shaped,
- a preformed section is used, the two flanges of which are on opposite lateral sides of the core, the cross section of the section being Z-shaped,
- a preformed section is used, the two flanges of which are astride the two lateral edges of the core, the cross section of the section being H-shaped,
- the preformed H-section is the result of the combination during its prior manufacture of two U shapes of composite material arranged soul-to-core,
- the two U-shaped shapes of composite material are two U-shaped profiles previously made and therefore rigid and which are fixed together,
- the two H forms of composite material are two previously made H-sections, which are thus rigid and which are fastened together,
- a complementary layer of complementary fiber plies is added to the free external main face of at least the sole which is not intended to be applied to the panel ,
- the plies of complementary fibers further continuously extend over the inner main face of the sole of the H-profile on both sides of the core, the plies being folded around the sole,
- the plies of complementary fibers further continuously extend over the inner main face of the sole of the H-profile while continuing on both sides of the core, the plies being folded around the sole and continuing on the soul,
- complementary layers of complementary fiber plies are added to the two free outer main faces of the two flanges of the H-profile during its prior manufacture
- panels are produced whose stacks of surface fiber plies comprise zones without resin or with unpolymerized resin, the said zones being intended to receive the profile manufactured beforehand,
- the sections produced beforehand are twisted
- the profiles manufactured beforehand are bypassed in their length
- the sections produced beforehand are twisted along their main axis / their length, the plates are flat,
- the plates are bypassed
- the panels are substantially planar and the profiles manufactured beforehand are straight longitudinally,
- the plates are intended for internal walls of ships or walls at interfaces between the outside and the inside of the ships,
- the plates are intended for dividing walls between two levels of the ship
- the dividing wall plates between two levels of the ship are substantially horizontal
- the plates are intended for dividing walls between two zones of the same level of the ship
- the separating wall plates between two zones of the same level of the ship are substantially vertical
- the plates are intended for communication walls extended between two levels of the ship and in particular form an access staircase from one level to the next,
- the previously manufactured sections are fixed to the panels by at least one of the following techniques: bonding or mechanical clamping, the bonding being carried out with or without the addition of additional plies of fibers, the mechanical tightening being chosen from screwing, bolting, riveting, the bonding being in particular vacuum bonding,
- the composite material comprises glass and / or carbon fibers and / or polymers and / or any other type of reinforcing fiber used in the composite field, secured by a resin,
- the composite material comprises all types of reinforcing fibers, in particular glass, aramid, carbon or equivalent and all types of matrix, in particular polyester, epoxy, vinylester or equivalent, possibly combined according to their compatibilities,
- the composite material and its resin are identical for previously manufactured profiles and panels,
- the composite material and possibly its resin are different for the profiles made beforehand and the panels,
- the inner main face of the sole has towards its free end, in the case of a U-profile, or at least one of its two free ends, in the case of a profile.
- H or T a return intended to form a trough bounded laterally by the soul and the return and delimited at the bottom by the inner main face of the sole,
- the U-profile comprises one or two returns to form respectively one or two chutes
- the H-profile comprises one to four returns to form respectively between one and four troughs
- the chutes are mainly used for ceilings and, preferably, those with their bottom (corresponding to the inner main face of the corresponding sole) down, for other use provisions, means of retention of cables or pipes being implemented to retain them in the troughs.
- the invention also provides a reinforced vessel wall plate comprising layered composite materials and specifically obtained by the method described.
- the reinforced plate thus results from the plate stiffening process and consists of at least one prefabricated section fixed on a panel.
- the invention also proposes a vessel comprising at least one reinforced plate according to the invention, said vessel being a surface or semi-submersible or submersible craft.
- FIG. 1 is a cross-sectional sectional view of a preformed H-section made of a composite, which has been assembled and fixed on a composite panel,
- FIG. 2 is a cross-sectional view of a preformed U-section made of a composite, which has been assembled and fixed on a composite panel,
- FIG. 3 is a cross-sectional view of an H-stiffener made from a pre-made composite T-section, which has been assembled and fastened to a composite panel with lamination resumption on the panel side.
- FIG. 4 is a cross-sectional view of a preformed H-shaped section made of composite and which has been assembled and fixed on a composite panel, said previously manufactured profile having two chutes due to the presence of two return elements. two of lateral ends free of soles.
- FIGS. 1 to 4 are sectional / cross sectional views, a reinforcing / stiffened plate obtained by the implementation of previously manufactured sections of the invention will be described.
- a floor or a deck or a partition has been made and it will be returned when installed in the ship structure, this explaining that the profiles are shown on top, position facilitating the realization of the plate in question .
- the profiles will be down, on the ceiling.
- stiffening elements which are, in the context of the invention, profiles made beforehand of composite material, are arranged for example in parallel strips or alignments or not on the panel and at a periodicity depending on the desired resistance for the plate. These bands or periodic alignments or not can also be crossed between them.
- the profiles are elongate elements that have a cross section of a specific shape with three parts in continuity: two flat soles in a straight section, straight if we consider the cross-section of the profile, and interconnected by a core flat in a straight section, right if you consider the profile section.
- the soles and the core when viewed in cross section of the profile are carried by separate axes, the axis carrying the core crossing the two bearing axes the soles typically at 90 ° and the two axes carrying the soles are parallel between them.
- the plate 1 comprises a panel 2 of laminated composite material on which is fixed a profile previously made 3a H-shaped cross-section of laminated composite material.
- the panel 2 is substantially flat and the profile 3a is a straight elongate member.
- the profile 3a made beforehand comprises, seen in cross section, two flanges 7 opposite straight and separated by a core 6 right, the flanges being perpendicular to the core and straddling the two opposite side edges (top and bottom in the figures in section / cross section) of the soul.
- the soles in this straight section are flat on their length and are carried by two parallel planes between them.
- the soul is flat on its length and is carried by a median plane which crosses the two planes carrying soles with 90 °.
- the pre-made profile that is installed on the panel 2 is structurally rigid.
- This profile 3a manufactured beforehand is obtained by stacking plies (or fabrics) of fibers which are finally taken in resin.
- the webs (or fabrics) of fibers are continuous from one sole to another through the soul.
- it is a fiberglass and oriented resin composite and the plies (or fabrics) of fibers are crossed with each other at +/- 45 ° in the stack of plies.
- a complementary layer 10 of plies (or fabrics) complementary fibers all also being taken by the resin.
- This complementary layer 10 may relate to the free flange (that which is not fixed to the panel) as shown in the figures or the other flange (not shown) or the two flanges of the profile (not shown).
- the orientation of the complementary layers of fibers of this layer complementary 10 is 0 °, that is to say in the longitudinal section of the profile. It will be seen that, in a particular embodiment, this previously made H-shaped profile can result from a combination of two U-shaped shapes of composite material. In another embodiment, this H profile is manufactured in a single operation.
- the sole 7, side of the panel 2, is fixed thereto by a structural bonding 4.
- a fixation by resumption of lamination and therefore with the provision of fiber sheets and resin is possible.
- the bonding and / or the resinization of the profiles made beforehand on the plate can use all the known techniques, especially as regards the supply of resin and / or glue, these elements being identical or not: the gluing of the profile manufactured beforehand can be done with a compound corresponding to the resin used to make the composite or other specific bonding compound.
- the same technique eg heating, irradiation, hardener / catalyst
- the profiles may, for example, be made by infusion, contact, "pre-preg" where the fiber webs used are pre-impregnated with resin or, "pultrusion” extrusion pulling fiber webs.
- the plate 1 comprises a panel 2 made of composite material on which is fastened a profile previously made 3b with a U-shaped cross-section.
- the flanges 7 ' are arranged laterally on one and the same lateral side of the core 6 but always towards the lateral edges (top down in the figure) of the core.
- the flanges may be on opposite lateral sides, still without overlapping, of the core, the cross-sectional shape of the profile then being more like a Z than a U.
- one of the two soles may be overlapping while the other is not.
- the layers of fibers are represented extending continuously between the two flanges via the core and a complementary layer 10 is formed on the free flange.
- the plate 1 of FIG. 3 there is indeed an H-shaped cross-section stiffening element, but it has been obtained from a previously made T-shaped profile 3c. of the assembly and fixing on the panel of the previously made T-section 3c, the T-shaped section 3c manufactured beforehand was arranged against the panel 2 by the free lateral edge (without sole, the bottom one in the figure) of its core 6 and layers of fibers 3d were extended on each side between the core and the panel, the whole having then been taken in resin to ensure a structural bonding of the T-shaped section 3c on the panel 2.
- this solution requires an additional step of laying additional layers of fibers and the aforementioned examples require only a resinization / gluing of the previously made profile 3a, 3b on the panel 2.
- the layers of fibers are continuously extended between the sole and the core and a layer complementary 10 is performed on the free sole.
- a reinforced plate 1 of the type of that of FIG. 1 is considered, but the profile previously made in H 3a that has been used this time comprises chutes 9 obtained by making returns 8 on the lateral ends of the soleplate. 7 free. These returns are oriented side of the soul and are substantially parallel to the last one. These chutes can serve as passage of cables or pipes.
- a metal chute or a metal strip is incorporated or glued / taken on the surface of the soleplate and possibly the core and / or possibly the return, during the prior manufacture of the profile , in case a relative shielding or continuous earth / ground protection is necessary.
- through openings may be made beforehand in the core to allow the passage of pipes or cables through the web of the profile.
- the basic shape for the production of the profiles is the U-shaped cross-section, with the two flanges of the same lateral side of the core, these three parts being substantially perpendicular to each other.
- This U-shaped section is made by stacking fiber plies, preferably cross-orientations between them for the oriented tablecloths.
- the plies are also continuous from one sole to another for most of the plies or, better, all plies.
- the H-shaped profile with two soles manufactured beforehand is obtained from the previous U-shape by joining / securing soul-to-core of two U-shaped sections.
- the fiber plies are generally separated into two sets belonging to the two lateral parts (each U-shaped) of the H-section, additional sheets of complementary fibers are added between these two lateral parts and thus extended to less on the free outer main face of the sole.
- These complementary plies are of course also taken in the resin to form the profile H made beforehand.
- two previously-made U-shaped sections instead of being joined soul-to-core to form an H-section, may be joined by the lateral ends of their respective flanges in order to form a tubular section of substantially square or rectangular cross-section according to the initial shapes of the U-shaped section, complementary layers of layers of fibers being preferably made on these contiguous soles to strengthen the joining of the two U-profiles.
- a T- or Z-shaped profile can be made from two contiguous L-shaped sections and an H-profile can be made from four contiguous L-sections.
- Other combinations are possible, for example to manufacture an H profile can be taken a Z-section and two L-shaped profiles.
- X or T or V connecting profiles can be manufactured beforehand in a view from above or below or in other forms that correspond to a cross or a connection between stiffening elements arranged in longitudinal orientations leading them to cross.
- X or T or V connecting profiles can be manufactured beforehand in a view from above or below or in other forms that correspond to a cross or a connection between stiffening elements arranged in longitudinal orientations leading them to cross.
- the cross sections of the arms of the previously made connection and profiles previously manufactured pursuing them will be identical, for example all H.
- connection splints made beforehand in composite can be attached to the two longitudinal ends end-to-end of two sections.
- previously formed strips of suitable shape, in particular made of L may be made for perpendicular attachment between a longitudinal end of a first profile and a full field, laterally, of a second section.
- one or several splints may be attached or made to the original on the profile manufactured beforehand.
- connection or crossing made beforehand and complementary longitudinal ends
- a cross or connection whose longitudinal ends of arms are hollow and in which the longitudinal ends of the profiles are inserted or fit .
- the invention can be applied perfectly to panels of curved shape, the profiles manufactured beforehand then being made curves complementary shape to that of the panel.
