1.1 <\/b>This International Standard specifies two methods for determining compressive properties, in directions parallel<\/p>\n
to the plane of lamination, of fibre-reinforced plastic composites.<\/p>\n
1.2 <\/b>The compressive properties are of interest for specifications and quality-control purposes.<\/p>\n
1.3 <\/b>Two loading methods and two types of specimen are described. They are:<\/p>\n
Method 1: provides shear loading of the specimen (gauge length unsupported).<\/p>\n
Method 2: provides end loading, or mixed loading, of the specimen (gauge length unsupported).<\/p>\n
NOTE For tabbed specimens end-loaded using method 2, some load is transferred into the specimen gauge length by<\/p>\n
shear through the tabs.<\/p>\n
Type A specimen: rectangular cross-section, fixed thickness, end-tabbed.<\/p>\n
Type B specimen: rectangular cross-section, range of thicknesses, untabbed or end-tabbed (two sizes<\/p>\n
available).<\/p>\n
Any combination of test method and specimen may be used, provided that the requirements of subclause 9.8 are<\/p>\n
satisfied and that the specimen is representative of the material under test. These alternative test conditions will not<\/p>\n
necessarily give the same result.<\/p>\n
The type A specimen is the preferred specimen for unidirectionally reinforced materials tested in the fibre direction.<\/p>\n
For other materials, the type A or B specimen may be used. The type B2 specimen is preferred for mat, fabric and<\/p>\n
other multidirectionally reinforced materials.<\/p>\n
1.4 <\/b>The methods are suitable for fibre-reinforced thermoplastic and thermosetting plastic composites.<\/p>\n
Unreinforced and particle-filled plastics, as well as those reinforced with short fibres (less than 1 mm in length), are<\/p>\n
covered by ISO 604 (see bibliography).<\/p>\n
1.5 <\/b>The methods are performed using specimens which may be machined from a test panel made in accordance<\/p>\n
with ISO 1268 or equivalent methods, or from finished or semi-finished products.<\/p>\n
1.6 <\/b>The methods specify required dimensions for the specimen. Tests which are carried out on specimens of other<\/p>\n
dimensions, or on specimens which are prepared under different conditions, may produce results which are not<\/p>\n
comparable. Other factors, such as the speed of testing, the support fixture used and the condition of the<\/p>\n
specimens, can influence the results. Consequently, when comparative data are required, these factors must be<\/p>\n
carefully controlled and recorded.<\/p>\n
1.7 <\/b>Fibre-reinforced plastics are usually anisotropic. It is therefore often useful to cut test specimens in at least the<\/p>\n
two main directions of anisotropy, or in directions previously specified (for example a lengthwise direction<\/p>\n
associated with the production process).<\/p>\n","protected":false},"excerpt":{"rendered":"
