Schicht aus Schaumstoffstreifen kann eine weitere harz-' getränkte Glasfaserschicht gelegt werden. Die Schaumstreifen können aus Polyurethan, Polyester, Polyäther und/oder Epoxy-Harz bestehen und elastisch sein. Die Glasfaserschieht kann aus ungeordneten Glasfasern und/ oder gewirkten bzw. gewebten Glasfasern bestehen. Ein solches Verfahren kann beispielsweise zur Herstellung von Bootskörpern verwendet werden.Layer of foam strips can be another resinous' soaked fiberglass layer are laid. The foam strips can consist of polyurethane, polyester, polyether and / or epoxy resin and be elastic. the Glass fiber layers can consist of disordered glass fibers and / or knitted or woven glass fibers. A such a method can be used, for example, for the manufacture of boat hulls.

Es besteht die Schwierigkeit, das Gebilde, welches relativ steif ist, in der Form, die konvexe und konkave Bereiche hat, zu halten, wobei es vor allen Dingen Schwierigkeiten bereitet, die Streifen in ihrer Lage zu halten. Bisher hat man dazu verschiedene Mittel zum Nie der drücken verwendet. There is a difficulty in the structure, which is relatively stiff, in the shape, the convex and concave areas has to hold, and above all it is difficult to hold the strips in place. Until now different means were used to keep the pressure low.

Der Erfindung liegt die Aufgabe zu Grunde, das Verfahren der eingangs erwähnten Art so durchzuführen, daß beim Aushärten das Gebilde insgesamt, insbesondere aber die Streifen einwandfrei in der Form verbleiben,The invention is based on the object to carry out the method of the type mentioned so that when The structure as a whole hardens, but in particular the strips remain perfectly in the form,

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Streifen höchstens 6,35 cm (2,5 Inch) breit und höchstens 4,45 cm (1,75 Inch) dick sind.This object is achieved according to the invention in that the strips are at most 6.35 cm (2.5 inches) wide and are at most 4.45 cm (1.75 inches) thick.

Auf diese Weise ist es möglich, ohne die Organe zum Niederdrücken auszukommen.In this way it is possible to do without the organs for depression.

In Bereichen vorspringender Flächen der Porms wo die Streifen häufig vorstehen, sollten die vorstehenden Stücke abgeschnitten und in das Gebilde gedruckt werden. S where projecting portions projecting surfaces of the strips Porm often, the projecting pieces should be cut and printed in the structure.

Die Winkel der Streifen können rechte sein. Erfindungsgemäß wird jedoch vorgeschlagen, daß die Streifen wenigstensThe angles of the strips can be right. According to the invention however, it is suggested that the strips at least

Einige Streifen sollten vorzugsweise mit nur einer schrägen Pläche versehen sein. Diese sind dann zur Herstellung einer Verbindung mit einer weiter unten erwähnten zusätzlichen Schicht besonders geeignet.Some strips should preferably have only one sloping surface. These are then ready for manufacture a connection with an additional layer mentioned below is particularly suitable.

Zwischen die Streifen dringt bei der Fertigstellung eine kleine Menge des flüssigen Harzes, so daß eine hervorragende Verbindung geschaffen wird.A small amount of the liquid resin penetrates between the strips during completion, so that an excellent one Connection is created.

Erfindungsgemäß wird ferner ..vorgeschlagen, daß in solche Bereiche der Form, die relativ eben sind und relativ groß sind, eine zusätzliche Schicht aus Schaummaterial gelegt wird, die parallele Nuten aufweist, deren Tiefe nur wenig geringer als die Dicke der zusätzlichen Schicht ist. Auf diese Weise wird Harz und Glasfasermaterial und zusätzlich auch Arbeitszeit eingespart. Die Nuten ermöglichen es, die Schicht nach Bedarf zu kürzen, derart daß man gewisse Streifen abbricht. Die Nuten können sich auf beiden Seiten der zusätzlichen Schicht befinden. Vorzugsweise sollten sie sich jedoch nur auf einer Seite der zusätzlichen Schicht befinden. Vorzugsweise sind die Nuten der Harzschicht zugewandt, derart daß das Harz beim Herstellen des Gebildes in die Nuten eindringt. Zweckmäßigerweise sollte der Abstand zwischen Nutengrund und gegenüberliegender Fläche ungefähr o,32 cm (1/8 Inch) betragen. According to the invention it is also proposed that in such Areas of the shape that are relatively flat and relatively large are placed an additional layer of foam material which has parallel grooves, the depth of which is only slightly less than the thickness of the additional layer. on This saves resin and fiberglass material and also saves working time. The grooves allow it is to shorten the layer as necessary, so that certain strips are broken off. The grooves can be on both sides of the additional layer. Preferably, however, they should only be on one side of the additional layer. Preferably, the grooves face the resin layer, so that the resin when Making the structure penetrates into the grooves. Appropriately, the distance between the bottom of the groove and opposite face should be approximately 0.32 cm (1/8 inch).

Erfindungsgemäß sind die ungefähren Ausmaße der zusätzlichen Schicht: 122 cm χ 61 cm χ max. 4,45 cm (4 ft. χ 2 ft. χ max. 1,75 Inch).According to the invention, the approximate dimensions of the additional layer are: 122 cm 61 cm χ max. 4.45 cm (4 ft. Χ 2 ft. Χ max. 1.75 inches).

Handelt es sich um zweifach gekrümmte Formen, können erfindungsgemäß weitere Nuten in die zusätzliche Schaumschicht eingebracht werden, die schräg oder senkrecht zu den erstgenannten Nuten -verlaufen.In the case of doubly curved shapes, according to the invention further grooves can be made in the additional foam layer, which are inclined or perpendicular to the the first-mentioned grooves.

In manchen Fällen ist es zweckmäßig, ein Füllmaterial zu verwenden. Erfindungsgemäß wird vorgeschlagen, daß auf die feuchte oder trockene harzaufweisende Schicht Füllmaterial mit Mikrogaseinschlüssen, das eine Dichte kleiner als 1 hat, aufgetragen wird und daß darauf die Schäumstoffstreifen gelegt werden. Die Mikrogaseinschlüsse können erfindungsgemäß durch kleine Glasballons gebildet sein. Die Verwendung eines Füllmaterials ist dann besonders zweckmäßig, wenn die harzaufweisende Schicht bei Weiterverarbeitung trocken ist. In diesem Falle stellt die Füllschicht die Verbindung zwischen den anderen Schichten her.In some cases it is useful to use a filler material. According to the invention it is proposed that on the wet or dry resinous layer of filler material with micro gas inclusions, which has a density less than 1, is applied and that the foam strips on it be placed. According to the invention, the micro gas inclusions can be formed by small glass balloons. The usage a filler material is particularly useful when the resin-containing layer is used for further processing is dry. In this case, the filling layer establishes the connection between the other layers.

Wenn der Schaumstoff in die Form gelegt worden ist und glasfaserverstärkter Kunststoff darüber gelegt werden soll, können sich Schwierigkeiten ergeben: Es kann nämlich geschehen, daß das Harz in die Poren des Schaumes eindringt, was unerwünscht ist. Außerdem kann die in den Poren befindliche Luft auf diesem Wege erwärmt werden und sich dann ausdehnen. Die glasfaserverstärkte Kunststoffschicht verformt sich infolgedessen. Erfindungsgemäß wird vorgeschlagen, die Poren mit einem Oberflächenfüller auszufüllen, bevor die glasfaserverstärkte Kunststoffschicht aufgetragen wird. Diese Füllschicht soll erfindungsgemäß eine Dichte kleiner als 1 haben. Das wird erreicht durch ein Füllmaterial mit Mikrogaseinschlüssen, die ebenfalls kleine G-lasballons sein können. Zweckmäßigerweise wird das Füllmaterial in die Poren hineingearbeitet, aber von der Oberfläche der Schaumstoffschicht entfernt.When the foam has been placed in the mold and glass fiber reinforced plastic is placed over it difficulties can arise: it can happen that the resin penetrates into the pores of the foam, what is undesirable. In addition, the air in the pores can be heated in this way and become then stretch. The glass fiber reinforced plastic layer is deformed as a result. According to the invention it is proposed fill the pores with a surface filler before applying the glass fiber reinforced plastic layer is applied. According to the invention, this filling layer should have a density of less than 1. That is achieved through a filling material with micro gas inclusions, which can also be small glass balloons. Appropriately this is Filler material worked into the pores, but removed from the surface of the foam layer.
