Abstract

The multi-layered sheet material is partic. suitable for the skin forming the hull of a boat. It consists of two layers of wood (I,III) of different thickness between which a web of fibreglass (II) is sandwiched under high pressure and with adhesive. The grains of the wood layers are parallel. The strength is greater than for conventional laminated three or multi-ply wood material with grains at 90 deg. and measured figures for Young's modulus and elasticity of flexure are given.

Voorrerpen gemaakt van samengestelde gewapende fineren 1 uit hout.Pre-bars made from composite reinforced wood veneers 1.

het is bekend dat het net behulp van lijn samenvoegen van houtfineren en deze onder druk te brengen, duplex-, triplex-, of multiplexplaten ontstaan.It is known that the net joining of wood veneers using line and pressurizing them creates duplex, plywood, or plywood panels.

Doordat de fineren onderling kruiselings onder hoeken van 5 90 gerangschikt en geperst worden berexkt men anaere sterkteeigen.se happen, dan als de fineren onderling niet kruiselings onder hoeken van 90° gerangschikt en gejfrst vi orden.Because the veneers are arranged and pressed crosswise at angles of 90 °, other strength-specific bites are obtained, if the veneers are not arranged and folded at an angle of 90 °.

Volgens de bekend zijnde technische gegevens van triplex en 10 multiplex geven de cijfers van de elasticiteitsmodulus en buigsterkte aan vrat technisch net het materiaal gedaan kan v/orden, zoals bijvoorbeeld het uit de cijfers kunnen berekenen hoe groot het zonder ondersteuning te overspannen oppervlak bedraagt.According to the known technical data of plywood and plywood, the figures of the modulus of elasticity and bending strength indicate that technical material can be done before the material can be prepared, such as, for example, calculating from the figures how large the surface area to be spanned without support.

lp kanvrager heeft een materiaal ontwikkeld bestaande uit 2 houtfineren van verschillende dikte met daartussen als wapening een glasgarenweefsel· Deze drie componenten v/orden onder hoge druk en hoge temperatuur met behulp van kook-v/atervaste lijm samengeperst. De draairichting van de fi-20 neren lopen in dit geval evenwijdig aan elkaar.lp kanvrager has developed a material consisting of 2 wood veneers of different thicknesses with a glass yarn fabric as reinforcement between them. These three components are pressed together under high pressure and high temperature using boiling-resistant glue. The direction of rotation of the veneers in this case is parallel to each other.

Van deze samenstelling, hierna te noemen -gewapend duplex- zijn sterktecijfars berekend door ΐ.ΙΤ,Ο., met als uitkomst ,·/ / '2 , voor da eiascxcxtexosnodulus // 15,01 lii/mm en voor de buigsterkte 175 ii/mm .Of this composition, hereinafter referred to as - reinforced duplex -, strength figures have been calculated by ΐ.ΙΤ, Ο., With the result, · / / '2, for da eiascxcxtexosnodulus // 15.01 lii / mm and for the bending strength 175 ii / mm.

25 Deze cijfermatige uitkomsten zijn aanzienlijk hoger dan de cijfermatige uitkomsten van triplex en multiplex in onge-_ wanende samenstelling, waarbij de fineren onderling onder Q ~- \ 790 5 2 52 %These numerical results are considerably higher than the numerical results of plywood and plywood in undesired composition, with the veneers mutually below Q ~ - 790 5 2 52%

Claims (2)

10 Door een -ontwerp van een boot of een jacht zo te Blaken dat een maximaal gebruik van de sterktecijfers en de mate van vervormbaarheid van het gewapende duplex wordt gemaakt, dan ontstaat een romp waarbij kielbalk, spanten, kis- en dekwe-gers, en kiellatten de aanhechtingsplaatsen vormen voor het 15 gewapend duplex. Hierdoor ontstaat een hull-constructie met als eigenschappen: - voldoende sterkte zoals is te berekenen uit de sterktecijf ers , - relatief laag in gewicht waardoor ballastverzwaring kan 20 worden toegepast en waardoor het zeilvoerendvermogen kan worden opgevoerd, - lager in gewicht daar gewapend duplex is teogepast, waar anders om tot gelijkwaardige sterktecijfers te komen zwaarder materiaal zou moeten worden toegepast, zoals 25 bijvoorbeeld: multiplex, gewapend polyester, aluminium,e.a. Bovendien kan worden gesteld dat het op deze wijze bouwen een re&atief goedkope bouw is, daar het gewapend duplex zich laat buigen en er geen gebruik wordt gemaakt van een mal. Conclusies.10 Blakening a design of a boat or yacht to maximize the strength ratings and deformability of the reinforced duplex creates a hull with keel bar, trusses, cleats and deckweighers, and keel battens form the attachment sites for the reinforced duplex. This results in a hull construction with the following properties: - sufficient strength as can be calculated from the strength figures, - relatively low in weight, so that ballast reinforcement can be applied and through which the sail-carrying capacity can be increased, - lower in weight, because reinforced duplex is used. , where otherwise heavier material would have to be used to arrive at equivalent strength figures, such as for instance: plywood, reinforced polyester, aluminum, etc. Moreover, it can be said that building in this way is a relatively cheap construction, since the reinforced duplex can be bent and no mold is used. Conclusions. 50 Gewapend duplex, bestaande uit *2 houtfineren van verschillende dikte waartussen met’behulp van kookwatervaste lijm een glasgarenweefsel onder hoge druk/ en hoge'temperatuur ( wordt samengenerst, waarbij de draadrichting van de fineren w:··'· evenwijdig aan elkaar lopen, geeft hogere sterktecijfers in % 790 5 2 52 3 > vergelijking net niet gewapende triple"- resp. multiplex- . n . - ^ O T 'daten ;aei: onderling erkaar onaer aoei-zen va.ii yO iiruiseziae ^insrsn* De generen sterftecijfers door 0. zijn voor de elastic!- p> 5 teitsacdulus // 15}0l ki;/m“ en voor de ouigsterkte // o T-7C -- / — -O ../-_Uj. · De gerrapen.de duplexplaat leent zich. uitstekend voor toepassing in de boten- en jachtbouw vanwege haar eigenschappen van vervormbaarheia en sterkte als verlangd kan worden voor 10 een economische bouw van een romp, waarbij kielbalk, spanten, dek- en kinwegers, en kiellatten de hechtplaatsen vormen voor het gewapend duplex. Verdere voordelen zijn: - het relatief lage soortelijk gewicht van het gewapend 1" dualex. - de ronpconstructie is zodanig te ontwerpen dat het maximale nut van laag gewicht samengaand met de cijfermatige uitkomsten zoals genoemd voor de elasticiteitsmodulus en de buigsterkte, en samengaand met de vervormbaarheid van 20 het gewapend duplex, zal leiden tot het kunnen opvoeren van het zeilveerend vermogen door oallastverzwaring, - door het relatief lage soerteiijk gewicht van het gewapend duplex zal ook het totaaigewicht van de boot of van het jacht reaatief en absoluut lager zijn dan in lengte verge- 25 lijkbare boten of jachten.

Due to the relatively low weight of the reinforced duplex, the total weight of the boat or yacht will also be reactive and absolutely lower than boats or yachts comparable in length. The transport of the boat or the yacht over land can be done for boats to be designed for that purpose. - the inflatable reinforced duplex makes it possible to build economically and competitively, since no use is made of building in or on a mold. 790 5 2 52
