För att minska vikten hos båtarna används även här kompositmaterial i skroven. Lägre vikt hos skrovet innebär större möjlighet att använda temporära skydd mot beskjutning beroende på den rådande hotnivån.To reduce the weight of the boats, composite material is also used in the hull. Lower weight of the hull means greater opportunity to use temporary protection against shelling depending on the current threat level.

Syftet med uppfinningen är att åstadkomma ett förbättrat båtskrov där skrovet är uppbyggt av tva olika komposit- material varvid övergången mellan de två olika komposit- materialen sker genom utfasning. Kompositmaterialkombina- tionen i båtskrovet enligt uppfinningen ger en god ballistisk skyddsförmåga, hög hàllfasthet samt minskad totalvikt hos båten.The object of the invention is to provide an improved boat hull where the hull is built up of two different composite materials, whereby the transition between the two different composite materials takes place by phasing out. The composite material combination in the boat hull according to the invention provides a good ballistic protective ability, high strength and reduced total weight of the boat.
Detta uppnås med ett båtskrov med en kompositmaterial~ kombination enligt de efterföljande självständiga patentkraven.This is achieved with a boat hull with a composite material combination according to the following independent claims.
Enligt uppfinningen anges ett bàtskrov med en övergång mellan ett första och ett andra kompositmaterial. Det första kompositmaterialet utgörs av ett konventionellt sandwichmaterial innefattande två yttre sidor omgivande en inre del och utgör den del av skrovet vilken företrädesvis befinner sig under oàtens vattenlinje; det andra komposit- materialet utgörs av ett ur hållfasthetsperspektiv över- dimensionerat enkeïskal och utgör sidorna av skrovet vilka företrädesvis befinner sig över båtens vattenlinje.According to the invention, a boat hull is provided with a transition between a first and a second composite material. The first composite material consists of a conventional sandwich material comprising two outer sides surrounding an inner part and constitutes the part of the hull which is preferably below the waterline of the oat; the second composite material consists of an ankle shell oversized from a strength perspective and constitutes the sides of the hull which are preferably above the boat's waterline.
Bátens vattenlinje definieras som gränsen på skrovet mellan den del som är över och den del som är under vattenytan då båten är obelastadi 10 15 20 25 30 532 94%? Enkelskalet tillverkas med en tjocklek vilken är från tre till tio gånger större än vad som normalt behövs för ett skrov vilket inte behöver ett gott ballistiskt skydd. Den ökade hållfastheten i skrovet medför, förutom en god ballistisk skyddstörmåga, dessutom att det behövs färre spant i båten vilket i sin tur medför en ökad inre volym hos skrovet. Det överdimensionerade enkelskalet i skrovets sidor medför också att det får en ökad stryktålighet vilket gör att båten tål ovarsam hantering mot t.ex. en kajkant utan att skador uppträder. Övergången mellan det första och det andra komposit- materialet i bàtskrovet enligt uppfinningen sker genom en kilformad utfasning av det första kompositmaterialet varvid det andra kompositmaterialet fasas in på det första kompositmaterialets yttre sidor. I det andra komposit- materialet kan även fästen gjutas in, pà den sidan vilken ska vara utsida, för att möjliggöra infästring av modulära tilläggsskydd.The boat's waterline is defined as the boundary of the hull between the part that is above and the part that is below the water surface when the boat is unloaded 10 15 20 25 30 532 94%? The single shell is manufactured with a thickness which is from three to ten times larger than what is normally needed for a hull which does not need good ballistic protection. The increased strength of the hull means, in addition to a good ballistic protective ability, in addition to the need for fewer frames in the boat, which in turn leads to an increased internal volume of the hull. The oversized single shell in the sides of the hull also means that it has an increased impact resistance, which means that the boat can withstand careless handling against e.g. a quay edge without damage. The transition between the first and the second composite material in the boat hull according to the invention takes place by a wedge-shaped phasing out of the first composite material, the second composite material being phased in on the outer sides of the first composite material. The brackets can also be molded into the other composite material, on the side which is to be the outside, to enable the attachment of modular additional protection.
Det konventionella sandwichmaterialet utgörs av en första och en andra sida av kolfiberarmerad polymer omgivande en mellanliggande cellkarna av skumplastmaterial. Det över- dimensionerade enkelskalet utgörs av en fiberarmerad polymer där fibern företrädesvis utgörs av glasfiber och/eller aramidfiber. Dessa fibrer ger en hög hàllfast hos enkelskalet och en god ballistisk skyddsförmàga mot kulor, splitter och stràlbildande projektiler (RSV). Polymeren i det överdimensionerade enkelskalet utgörs företrädesvis av en vinylestermatris, En fenolbaserad matris kan användas på den sida av enkelskalet vilken utgör skrovets insida för att förbättra brandskyddet. Ett tunt lager av ett halv- 10 15 20 25 30 532 945 ledarskikt, företrädesvis av kolfiber, på den sida av enkelskalet vilken utgör skrovets utsida, medför att bàten får förbättrade radaregenskaper, t.ex. blir mer svår- upptäckt.The conventional sandwich material consists of a first and a second side of carbon fiber reinforced polymer surrounding an intermediate cell core of foam material. The oversized single shell consists of a fiber-reinforced polymer, where the fiber preferably consists of glass fiber and / or aramid fiber. These fibers provide a high strength of the single shell and a good ballistic ability to protect against bullets, splinters and beam-forming projectiles (RSV). The polymer in the oversized single shell is preferably a vinyl ester matrix. A phenol based matrix can be used on the side of the single shell which forms the inside of the hull to improve fire protection. A thin layer of a semi-conductive layer, preferably of carbon fiber, on the side of the single shell which forms the outside of the hull, means that the boat has improved radar properties, e.g. becomes more difficult to detect.
I båtskrovet enligt uppfinningen har det överdimensionerade enkelskalet företrädesvis en tjocklek från l5 mm till 50 mm. Det konventionella sandwicnmaterialet har företrädesvis en tjocklek från 3G mm till 60 mm.In the boat hull according to the invention, the oversized single shell preferably has a thickness from 15 mm to 50 mm. The conventional sandwich material preferably has a thickness from 3G mm to 60 mm.
Uppfinninqen skall i det följande närmare beskrivas i anslutning till bifogade figurer.The invention will be described in more detail below in connection with the accompanying figures.
Figur 1 visar bàtskrovet med det forsta kompositmaterialet utgorande den del av skrovet vilken befinner sig under vattenlinjen och det andra kompositmaterialet utgorande sidorna av skrovet vilka befinner sig över vattenlinjen; Figur 2 visar en ftrstoring av övergången mellan det första kompositmaterialet och det andra kompositmaterialet i bàtskrovet enligt uppfinningen.Figure 1 shows the boat hull with the first composite material constituting the part of the hull which is below the waterline and the second composite material constituting the sides of the hull which are above the waterline; Figure 2 shows a magnification of the transition between the first composite material and the second composite material in the boat hull according to the invention.
Enligt ett foredraçet utforingsexempel anges ett båtskrov med en uppbyggnad enligt figur 1 och tillverkat enligt SCRIMP®-metoden. Sandwichmaterialet (l, 2, 3) utgör skrovet under vattenlinjen (7) och består av två 3 mm tjocka ytter- sidor (1, 2) av kolfiberarmerad polymer vilka omger en mellanliggande cellkärna (3) av Divinycell® med en tjocklek av 50 mm. Enkelskalet (4) utgör sidorna av skrovet över vattenlinjen (7) och består 40 mm tjock glasfiberarmerad vin lester. Materialöver ån en (5 ors enom en kilformad G utfasning av sandwicnmaterialet (l, 2, 3) varvid enkel- 10 15 532 543 skalet (4) fasas it på sandwicnmaterialets yttersidor (l, 2). Fästen (6) i aluminium har gjutits in på enkelskalets (4) utsidor för att möjliggöra infästning av modulära tilläggsskydd. En förstoring av materialovergángen (5) ses i figur 2.According to a preferred embodiment, a boat hull is indicated with a structure according to Figure 1 and manufactured according to the SCRIMP® method. The sandwich material (1, 2, 3) forms the hull below the waterline (7) and consists of two 3 mm thick outer sides (1, 2) of carbon fiber reinforced polymer which surround an intermediate cell core (3) of Divinycell® with a thickness of 50 mm . The single shell (4) forms the sides of the hull above the waterline (7) and consists of 40 mm thick fiberglass reinforced wine lester. Material over one (5 years by a wedge-shaped G phasing out of the sanding material (1, 2, 3) whereby the single shell (4) is phased in on the outer sides (1, 2) of the sanding material. on the outside of the single shell (4) to enable the attachment of modular additional protection, an enlargement of the material transition (5) is shown in figure 2.
Enligt ytterligare ett föredraget utforingsexempel anges ett båtskrov med ett enkelskal bestående av en mot båtens inre del fenolbaserad matris och tillverkat enligt CIRTM- metoden, anpassad för SCRIMP®“metoden. Den fenolbaserade matrisen utgör en tredjedel av enkelskalets tjocklek och förbättrar båtens brandskydd. På den sidan av enkelskalet vilken utgör utsida inkluderas ett 0,8 mm tjockt lager av halvledande kolfiber vid tillverkningen. Det nalvledande kolfibermaterialet nedför en signaturenpassning vilket gör att risken att båten upptäcks via radar minskar.According to a further preferred embodiment, a boat hull is provided with a single shell consisting of a matrix based on the inner part of the boat and manufactured according to the CIRTM method, adapted for the SCRIMP® method. The phenol-based matrix makes up a third of the single-shell thickness and improves the boat's fire protection. On the side of the single shell which forms the outside, a 0.8 mm thick layer of semiconducting carbon fiber is included in the manufacture. The needle-conducting carbon fiber material lowers a signature fit, which reduces the risk of the boat being detected by radar.
