标准范围

1.1本国际标准规定了两种测定压缩性能的方法，在平行方向上到纤维增强塑料复合材料的层压平面。1.2为了规范和质量控制的目的，压缩性能是有意义的。1.3描述了两种加载方法和两种类型的试件。它们是:方法1:提供试样的剪切载荷（标距无支撑）。方法2:提供试样的端部加载或混合加载（标距无支撑）。注:对于使用方法2进行端部加载的带标签试样，一些载荷通过以下方式转移到试样标距长度中穿过拉环。A型试样:矩形截面，固定厚度，端部有突片。B型试样:矩形横截面，厚度范围，无凸片或端部-标签式（两种尺寸可用）。可以使用试验方法和试样的任何组合，前提是满足第9.8款的要求满意，并且样品代表受试材料。这些替代测试条件不会必然会给出相同的结果。A型试样是沿纤维方向测试的单向增强材料的优选试样。对于其他材料，可以使用A型或B型试样。B2型样品优选用于垫子、织物和其他多向增强材料。1.4这些方法适用于纤维增强的热塑性和热固性塑料复合材料。未增强和颗粒填充塑料，以及用短纤维（长度小于1毫米）增强的塑料ISO 604涵盖（见参考书目）。1.5这些方法是使用可由根据以下规定制造的测试面板加工而成的样本进行的使用ISO 1268或同等方法，或来自成品或半成品。1.6这些方法规定了样品所需的尺寸。对其他样本进行的测试尺寸，或在不同条件下制备的样品上，可能会产生不可比。其他因素，例如测试速度、使用的支撑夹具和设备的状况标本，会影响结果。因此，当需要比较数据时，这些因素必须仔细控制和记录。1.7纤维增强塑料通常是各向异性的。因此，通常有用的是至少在各向异性的两个主要方向，或在先前指定的方向上（例如纵向与生产过程相关）。

1.1 This International Standard specifies two methods for determining compressive properties, in directions parallelto the plane of lamination, of fibre-reinforced plastic composites.1.2 The compressive properties are of interest for specifications and quality-control purposes.1.3 Two loading methods and two types of specimen are described. They are:Method 1: provides shear loading of the specimen (gauge length unsupported).Method 2: provides end loading, or mixed loading, of the specimen (gauge length unsupported).NOTE For tabbed specimens end-loaded using method 2, some load is transferred into the specimen gauge length byshear through the tabs.Type A specimen: rectangular cross-section, fixed thickness, end-tabbed.Type B specimen: rectangular cross-section, range of thicknesses, untabbed or end-tabbed (two sizesavailable).Any combination of test method and specimen may be used, provided that the requirements of subclause 9.8 aresatisfied and that the specimen is representative of the material under test. These alternative test conditions will notnecessarily give the same result.The type A specimen is the preferred specimen for unidirectionally reinforced materials tested in the fibre direction.For other materials, the type A or B specimen may be used. The type B2 specimen is preferred for mat, fabric andother multidirectionally reinforced materials.1.4 The methods are suitable for fibre-reinforced thermoplastic and thermosetting plastic composites.Unreinforced and particle-filled plastics, as well as those reinforced with short fibres (less than 1 mm in length), arecovered by ISO 604 (see bibliography).1.5 The methods are performed using specimens which may be machined from a test panel made in accordancewith ISO 1268 or equivalent methods, or from finished or semi-finished products.1.6 The methods specify required dimensions for the specimen. Tests which are carried out on specimens of otherdimensions, or on specimens which are prepared under different conditions, may produce results which are notcomparable. Other factors, such as the speed of testing, the support fixture used and the condition of thespecimens, can influence the results. Consequently, when comparative data are required, these factors must becarefully controlled and recorded.1.7 Fibre-reinforced plastics are usually anisotropic. It is therefore often useful to cut test specimens in at least thetwo main directions of anisotropy, or in directions previously specified (for example a lengthwise directionassociated with the production process).
