Definitions
- the present invention relates in general to a FRP hull structure of a ship, and more particularly to an improvement of a FRP hull structure of a multi-hull type ship to achieve a desired strength and a desired high speed of the ship.
- Fig. 1 is a side view of a conventional SES.
- the multi-hull ship or the catamaran means a ship having a twin hull structure of which the two box-shaped hulls are spaced apart from each other and submerged under water.
- the over-deck structure which includes the passengers quarters, a steering house and the like, is placed on a deck which is spanned between the two box-shaped hulls and connects the hulls together.
- the surface effect ship (SES) has a hull structure section which is basically equal to that of the above catamaran but has seals provided on the front and rear sections of the twin hull, respectively.
- the lower hull structure under a main deck 1 comprises a twin hull part and a wet deck part D extended between the twin hull part.
- the twin hull part comprises a side plate section A, a bottom plate section B, an inner plate section C.
- the lower hull structure including the plate sections A, B and C and the wet deck part D, may have a laminated single skin structure which is prepared by lamination of a plurality of laminated FRP panels as shown in Fig. 2A.
- the lower hull structure may have a sandwich structure which has a PVC foam substrate of a predetermined thickness reinforced by laminated FRP panels bonded to the inner and outer surfaces of the PVC foam substrate, respectively, as shown in Fig. 2B.
- the hull structure When the ship having the laminated single skin structure for all of the plate sections A, B and C, and the wet deck part D, the hull structure has a desired strength.
- the ship having the hull structure of the laminated single skin structure unfortunately collides with a floating material or runs on a reef during a high speed running or at anchor, it is reliably prevented from being damaged and wrecked, thus to guarantee the safety of the passengers.
- this single skin hull structure also has a problem that it inevitably causes a difficulty in its preparation due to the stiffener 4 which should be added to the single skin hull structure.
- Another problem of this single skin hull structure is resided in that it can not achieve the lightness of the structure, regarded as the most important point of the high speed ship, thus to scarcely achieve a desired high speed of the ship.
- an object of the present invention to provide a combined FRP hull structure of a multi-hull type ship in which the aforementioned problems of the known hull structures can be overcome and which comprises a twin hull part having a laminated single skin structure prepared by lamination of a plurality of laminated FRP panels, and a wet deck having a sandwich structure prepared by bonding laminated FRP panels to upper and lower surfaces of a PVC foam substrate of a predetermined thickness, respectively, thus to reliably prevent a partial damage of the twin hull part even when the twin hull part unfortunately collides with a floating material or runs on a reef during a high speed running or at anchor, to guarantee the safety of the passengers, to lengthen the life of the hull structure and to achieve the lightness of the hull structure, the most important point of the high speed ship.
- a combined FRP hull structure of a multi-hull type ship in accordance with the present invention comprises: at least two hulls and a wet deck extending between the hulls, each of the hulls having a laminated single skin structure, the laminated single skin structure being prepared by lamination of a plurality of laminated FRP (fiberglass reinforced plastic) panels, each of the laminated FRP panels being prepared using a fiber material laden with a resin; and the wet deck having a sandwich structure, the sandwich structure being prepared by bonding the laminated FRP panel, comprising the fiber material laden with the resin, to each of upper and lower surfaces of a PVC foam substrate having a predetermined thickness.
- FRP fiberglass reinforced plastic
- the fiber material of the laminated FRP panel is selected from an aramid fiber material and a glass fiber material and the resin of the laminated FRP panel is an isophthalic type resin.
- the bonding of the laminated FRP panels of the sandwich structure of the wet deck to the upper and lower surfaces of the PVC foam substrate is achieved by a vacuum bagging, using an unsaturated acrylate resin as a bonding agent applied to interfaces between the laminated FRP panels and the upper and lower surfaces of the PVC foam substrate.
- Fig. 1 is a side view of a surface effect ship (SES);
- Figs. 2A and 2B are partial cross sectional views of conventional hull structures, respectively, in which: Fig. 2A shows a conventional laminated single skin structure; and
- Fig. 2B shows a conventional sandwich structure
- Fig. 3 is a schematic cross sectional view of SES having a combined FRP hull structure in accordance with a preferred embodiment of the present invention.
- Figs. 4A and 4B are partial enlarged sectional views of two parts of the combined FRP hull structure of the ship of Fig. 3, respectively, in which:
- Fig. 4A shows a laminated single skin structure of a twin hull part
- Fig. 4B shows a sandwich structure of a wet deck part.
- Fig. 3 schematically shows a combined FRP hull structure of a surface effect ship (SES) according to a preferred embodiment of the present invention
- Fig. 4A shows a laminated single skin structure of a twin hull part
- Fig. 4B shows a sandwich structure of a wet deck part.
- the lower hull structure of this high speed passenger ship includes a twin hull part and a wet deck part D.
- the twin hull part comprises three plate sections, that is, a side plate section A, a bottom plate section B and an inner plate section C.
- the twin hull part including the side plate section A, the bottom plate section B and the inner plate section C, has a laminated single skin structure which is prepared by lamination of a plurality of FRP (fiberglass reinforced plastic) panels 2.
- FRP fiberglass reinforced plastic
- each of the FRP panels 2 is prepared using an aramid fiber mat or a glass fiber mat, the two types of fiber mats being laden with an isophthalic type resin.
- examples of the raw materials used in preparation of the laminated single skin structure of the twin hull part are a surface mat, a chopped strand mat, an uni-di rectional tape, a bi-axial mat, an aramid fiber, an urethane foam, gel coat, an isophthalic resin, an urethane acrylate resin and etc..
- the wet deck part D which is extended between the both hulls of the twin part under the main deck 1 and stretched over the water, has a sandwich structure.
- a laminated FRP panel 2' comprising a fiber mat laden with an isophthalic type resin, is bonded to each of the upper and lower surfaces of a PVC foam substrate 3 by vacuum bagging.
- an unsaturated acrylate resin as a bonding agent is applied to the interfaces between the laminated FRP panels 2' and the upper and lower surfaces of the PVC foam substrate 3.
- examples of the raw materials used in preparation of the sandwich structure of the wet deck part D are a glass fiber, an aramid fiber, a PVC foam, an isophthalic type resin, an unsaturated acrylate resin and etc..
- the side plate section A, the bottom plate section B and the inner plate section C which constitute the twin hull part, comprise the laminated single skin structure which is prepared by lamination of the plurality of FRP panels 2, each of the FRP panels 2 being prepared using the fiber mat laden with the isophthalic type resin.
- the structure of the twin hull part is thus remarkably increased in its thickness in comparison with the known twin hull structure comprising the sandwich structure.
- this twin hull part having the laminated single skin structure reliably prevents its partial damage even when it is unfortunately imparted with a local impact load, such as caused by collision with a floating material or running on a reef during a high speed running or at anchor.
- this twin hull part having the laminated single skin structure guarantees the safety of the passengers.
- the wet deck part D has the sandwich structure prepared by bonding the laminated FRP panels 2, each comprising the fiber mat laden with the isophthalic type resin, to the upper and lower surfaces of the PVC foam substrate 3, respectively. Thanking for such a sandwich structure, the wet deck part D has a sufficient shear strength for resisting a slamming pressure conventionally acting thereon when the high speed ship rises to the water surface and slides on the water surface at a high speed. In addition, this wet deck part D having the sandwich structure is reduced in the thickness of the laminated panels 2' in comparison with the known wet deck part having the laminated single skin structure, thus to reduce the weight and to achieve the lightness of the ship, the most important point of the high speed ship.
- the twin hull part has a laminated single skin structure and the wet deck part has a sandwich structure.
- the laminated single skin structure of the twin hull part is prepared by lamination of a plurality of FRP panels, each being prepared using a fiber mat laden with an isophthalic type resin.
- the sandwich structure of the wet deck part is prepared by bonding the laminated FRP panel, comprising the fiber mat laden with the isophthalic type resin, to each of the upper and lower surfaces of a PVC foam substrate by vacuum bagging.
- the twin hull part having the laminated single skin structure reliably prevents its partial damage even when it is unfortunately imparted with a local impact load, such as caused by collision with a floating material or running on a reef during a high speed running or at anchor, so that it guarantees the safety of the passengers.
- the wet deck part having the sandwich structure has a sufficient shearing strength for resisting a slamming pressure and is reduced in the thickness of the laminated panels, thus to achieve the lightness of the ship and a desired high speed.
- This sandwich structure of the wet deck part also simplifies the manufacturing process and reduces the manufacturing cost since it requires no additional reinforcement, such as ⁇ tiffeners.

Abstract
L'invention concerne une structure de coque de bateau multicoque combinant une structure en simple épaisseur de stratifié pour le bordé et une structure sandwich. La structure de coque comporte au moins deux coques et un pont humide joignant les deux coques. La structure de bordé de chaque coque est en simple épaiseur de stratifié, réalisé par stratification de plusieurs panneaux de plastique renforcés par des fibres, chacun d'entre eux ayant été confectionné à partir d'un mat de fibre chargé de résine de type isophthalique. La structure du pont humide est de type sandwich, réalisée en assemblant les panneaux de plastique stratifiés renforcés par des fibres sur les surfaces supérieure et inférieure d'un substrat en mousse de polychlorure de vinyle d'une épaisseur prédéterminée. Le mat de fibre du panneau de plastique stratifié est au choix un mat en fibre aramide ou un mat en fibre de verre. L'assemblage des panneaux de plastique stratifié de la structure sandwich du pont sur les faces supérieure et inférieure du substrat en mousse PVC est réalisé par moulage au sac sous vide, à l'aide d'une résine d'acrylate insaturé comme agent adhésif que l'on applique entre les panneaux de plastique stratifiés et les faces supérieure et inférieure du substrat en mousse de polychlorure de vinyle. Cette combinaison de structures de coque confère au bateau une résistance souhaitée et des possibilités de vitesse élevée.
