Fibre-reinforced plastics - Methods of producing test plates - Part 1 : general conditions

<p>The various parts of ISO 1268 (see the foreword) describe methods used to prepare reinforced-plastics plates from</p> <p>which test specimens can be cut. This allows the properties of a composite, or the constituents of the composite, to</p> <p>be determined. The methods are intended to cover all the main types of reinforcement and resin matrix.</p> <p>The choice of test plate preparation method depends on:</p> <p>a) the reinforcement:</p> <p> its nature (glass, carbon, aramid, etc.);</p> <p> its form (roving, mat, woven fabric, etc.);</p> <p> its orientation with respect to the length, width and thickness of the plate;</p> <p> its content in the reinforced plastic;</p> <p>b) the matrix (thermosetting or thermoplastic);</p> <p>c) the magnitude expected for the properties;</p> <p>d) the production process that is to be evaluated.</p> <p>Since the mechanical properties of a reinforced plastic are known to be dependent on the process by which the</p> <p>plastic is produced, it is recommended that the test plates be prepared, if possible, by the same method that will be</p> <p>used to produce the plastic.</p> <p>This part of ISO 1268 describes the general requirements common to all the methods.</p>

<p> La présente partie de l'ISO 1268 décrit la fabrication de plaques en plastiques renforcés par les méthodes de moulage au contact ou par projection. Elle s'applique exclusivement aux renforts en fibre de verre et doit être lue conjointement avec l'ISO 1268-1. </p>

Fibre-reinforced plastics - Methods of producing test plates - Part 3 : wet compression moulding

<p> La présente partie de l'ISO 1268 spécifie une méthode permettant de fabriquer des plaques d'essai par moulage par compression voie humide. Selon cette technique les plaques d'essai peuvent être fabriquées de façon reproductible, ce qui permet de comparer les résultats des essais effectués à des périodes différentes et/ou en différents emplacements. Les éprouvettes découpées dans les plaques fabriquées par moulage par compression humide permettent de caractériser le type de renforcement utilisé. Ce renforcementt peut être constitué de mats ou de tissu. Les caractéristiques spécifiques suivantes de ces matériaux présentent un intérêt particulier: - l'absorption d'eau (ISO 62, Plastiques - Détermination de l'absorption d'eau); - la résistance à la flexion et le module de flexion (ISO 178); - la résistance au choc (Charpy) (ISO 179); - la résistance à la traction, le module de traction et l'allongement à la rupture (ISO 527-4). La présente partie de l'ISO 1268 est destinée à être utilisée conjointement avec l'ISO 1268-1. </p>

Fibre-reinforced plastics - Methods of producing test plates - Part 4 : moulding of prepregs

<p>ISO 1268-4:2005 describes the preparation of test plates from layers of preimpregnated unidirectional fibre or fabric (prepregs) under pressure and temperature in various types of equipment (for example, autoclave, bladder press, hydraulic press or vacuum bag equipment). It applies to all reinforcements and resins.</p> <p>This method is applicable to reinforcements preimpregnated either with a partially cured thermosetting resin or with a thermoplastic resin. The test plate is formed by stacking layers of the preimpregnated material in the required sequence and orientation, followed by compaction and final consolidation under pressure/vacuum at a temperature above ambient. The prepared test plates are subsequently machined into the required test specimens.</p> <p>Standard plates prepared in this manner may be used either for evaluating the components, i.e. the reinforcement, finish, resin, etc., or for verifying the overall quality of the finished product.</p>

Fibre-reinforced plastics - Methods of producing test plates - Part 5 : filament winding

<p> La présente partie de l'ISO 1268 décrit une méthode de fabrication de plaques en plastiques renforcés par la méthode de l'enroulement filamentaire à partir de stratifils (rovings) et d'un bain de résine (elle ne concerne pas les mèches préimprégnées). Elle a pour objet la fabrication, dans des conditions industrielles optimales, de plaques à renfort unidirectionnel pour le découpage d'éprouvettes destinées aux divers essais mécaniques statiques. La présente partie de I'ISO 1268 est établie pour des plastiques renforcés de fibre de verre à matrice en résine polyester ou époxyde, mais peut être étendue à d'autres types de résines et de renforts. Elle doit être lue en parallèle avec l'ISO 1268-1. <br/> <br/>NOTE Pour améliorer la clarté de cette méthode, et sauf mention particulière qui s'y oppose, le mot «stratifil» est utilisé dans l'ensemble du texte pour désigner également les fils. </p>

Fibre-reinforced plastics - Methods of producing test plates - part 8 : compression moulding of SMC and BMC

<p>ISO 1268-8:2004 specifies the general principles and procedures for the compression moulding of test plates from two types of fibre-reinforced thermosetting moulding compound: sheet moulding compound (SMC) and bulk moulding compound (BMC). Two different methods are given for preparing the mould charge: method A for moulding without the material flowing in the mould and method B for moulding so that the material flows in the mould.</p>

<p>ISO 1268-9:2003 specifies a method for preparing test plates by compression moulding of reinforced thermoplastic sheet (GMT/STC) to be used for the preparation of test specimens to determine the mechanical and physical properties of the laminate. The proposed method is applicable to laminates made from a thermoplastic matrix reinforced with glass, carbon, aramid or other reinforcing fibres, alone or in combination and in any form suitable for compression moulding.</p>

Fibre-reinforceds plastics - Methods of producing test plates - Part 10 : injection moulding of BMC and other long-fibre moulding compounds - General principles and moulding of multipurpose test specimens

<p>ISO 1268-10:2005 specifies the general principles to be followed while injection moulding test specimens of bulk moulding compound (BMC) and gives details of mould designs for preparing one type of specimen for use in establishing reproducible moulding conditions. Where appropriate, this part of ISO 1268 may be applied to sheet moulding compound (SMC) formulated for injection moulding. Its purpose is to promote uniformity in describing the main parameters of the moulding process and also to establish uniform practice in reporting moulding conditions. The particular conditions required for the reproducible preparation of test specimens which will give comparable results will vary for each material used. These conditions are given in the International Standard for the relevant material or are to be agreed upon between interested parties.</p>

The moulds may additionally be fitted with inserts for studying the effects of weld lines on the mechanical properties.</p>
