Abstract

The assembly, made on a rolling machine, consists of inner and outer skins on either side of a framework of I-beams, all made from a fibre composition material and a thermosetting resin. The I-beams are made by cutting them from rolled hollow elements prior to stoving, and they are assembled to form rigid hollow frame sections which are filled with foam panels, e.g. of melamine.

Description

La présente invention concerne un ensemble structural en matériaux composites thermodurcissables, réalisé sur une machine d'enroulement filamentaire, représentant un chaudron de voiture de transport. The present invention relates to a structural assembly of thermosetting composite materials, produced on a filament winding machine, representing a cauldron of a transport car.

Ce chaudron est composé de trois éléments principaux:un revêtement intérieur, une ossature composée de profilés, et un revêtement extérieur; de plus avant le revêtement extérieur,est déposée une mousse d'isolation,l'ensemble de ces matériaux étant classé: feu fumée.This cauldron is made up of three main elements: an interior covering, a framework composed of profiles, and an external covering; moreover before the external covering, an insulation foam is deposited, all of these materials being classified: smoke fire.

Cette invention rient compléter et améliorer le brevet français 9300906. Le démoulage délicat des grandes longueurs est suppri-mé.Les éléments rectangulaires jointifs sont remplacés par une autre ossature plus facile d'utilisation surtout en partie courbe, et de plus, cette nouvelle technique permet de déposer la mousse d'isolation en cours de fabrication sans difficulté.Cette nouvelle conception diminue le temps de main-d'oeuvre, permet l'incorporation de l'isolant à l'intérieur de l'ossature, ce qui augmente la largeur utilisable de la voiture finie c'est un confort supplémentaire, un moindre coût pour la finition intérieure et un allègement non négligeable- de la voiture.This invention laugh complete and improve the French patent 9300906. The delicate release of long lengths is suppri-mé.The rectangular adjoining elements are replaced by another frame easier to use especially in the curved part, and moreover, this new technique allows to deposit insulation foam during manufacture without difficulty. This new design reduces labor time, allows the incorporation of insulation inside the framework, which increases the usable width of the finished car it is an additional comfort, a lower cost for the interior finish and a significant reduction - of the car.

Le but recherché de cette invention: l'industrialisation à moindre coût de tous types de voiture de transport en apportant la légèreté des matériaux composites, sans réduire la rigidité de l'ensemble. The aim of this invention: the industrialization at low cost of all types of transport car by bringing the lightness of composite materials, without reducing the rigidity of the assembly.

La fabrication est entièrement réalisée par enroulement filamentaire sur machine horizontale pour les profilés, sur machine verticale de préférence pour l'ensemble du chaudron. The manufacturing is carried out entirely by filament winding on a horizontal machine for the profiles, on a vertical machine preferably for the whole cauldron.

Les profilés en I (fig.1) qui composent ossature sont de fabrication spéciale. The I-shaped profiles (fig. 1) which make up the framework are specially manufactured.

1) On réalise sur des tubes rectangulaires servant de mandrin un enroulement de fibre et de résine,et on rassemble ceux-ci les uns contre les autres en les pressant (fig.2). 1) A winding of fiber and resin is made on rectangular tubes serving as a mandrel, and these are brought together against each other by pressing them (fig. 2).

2) On étuve l'ensemble, et après durcissement, on découpe par le milieu dans le sens longitudinal,l'ensemble des tubes pour obtenir des I (fig.3). De la même façon, on réalise les profilés servant d'éléments transversaux (fig.4). 2) The whole is steamed, and after hardening, the set of tubes is cut through the middle in the longitudinal direction, to obtain I (fig.3). In the same way, the profiles serving as transverse elements are produced (fig. 4).

Il faut noter que ces profilés peuvent être réalisés par pultrusion avec des inconvénients: mauvaise tenue en torsion et surtout 40% de poids en plus. L'épaisseur minimum de fabrication est bien supérieure à l'enroulement.It should be noted that these profiles can be produced by pultrusion with drawbacks: poor torsional resistance and above all 40% more weight. The minimum manufacturing thickness is much greater than the winding.

Les profilés étant fabriqués, on réalise le montage des panneaux formant l'ossature, sur un plateau de grande dimension (fig.5). La longueur des panneaux représentant celle du chaudron et la largeur pouvant avoir une inci- dence en fonction des parties courbes ou des ouvertures.The profiles being manufactured, the panels forming the framework are mounted on a large plate (fig. 5). The length of the panels representing that of the cauldron and the width which may have an effect depending on the curved parts or the openings.

Les profilés longitudinaux sont reliés entre eux par des profilés tranversaux au moyen de collage
A l'intérieur des cadres ainsi formés on dépose une mousse de faible densité type mélamine par exemple classée feu fumée de bonne isolation thermique et phonique.The longitudinal sections are interconnected by transverse sections by means of bonding
Inside the frames thus formed, a low density melamine type foam is deposited, for example classified as a smoke fire with good thermal and sound insulation.

L'opération qui suit, l'assemblage du chaudron, est réalisée de préférence sur une machine verticale d'enroulement filamentaire. Sur le plateau de la machine verticale, on dépose le mandrin représentant la forme intérieure du chaudron
Au préalable, une couche de gel-coat a été déposée sur le mandrins. Ensuite on enroule des couches de fibre et résine pour atteindre 11 épaisseur désirée.The following operation, the assembly of the cauldron, is preferably carried out on a vertical filament winding machine. On the platform of the vertical machine, place the mandrel representing the interior shape of the cauldron
Beforehand, a layer of gel-coat was deposited on the mandrels. Then layers of fiber and resin are rolled up to achieve the desired thickness.

La deuxième opération consiste à plaquer les panneaux d'ossature contre les parois verticales du mandrin qui vient de recevoir l'enroulement. The second operation consists in pressing the framework panels against the vertical walls of the mandrel which has just received the winding.
