标准范围
1.1 This document specifies methods for determining the compressive properties, in directions parallel to the plane of lamination, of fibre-reinforced plastic composites, based on thermosetting or thermoplastic matrices. The compressive properties are of interest for specifications and quality- control purposes. The test specimens are machined from a flat test plate, or from suitable finished or semi-finished products. 1.2 Two loading methods and two types of specimen are described. The loading methods are: — Method 1: provides shear loading of the specimen (gauge length unsupported) — Method 2: provides combined loading of the specimen (gauge length unsupported) NOTE For tabbed specimens loaded using method 2, load is transferred through a combination of end- loading and shear-loading through the tabs. The specimen designs are: — Type A specimen: rectangular cross-section, fixed thickness, end-tabbed (mainly for aerospace style preimpregnates (~ 0,125 mm ply thickness) — Type B specimen: rectangular cross-section, range of thicknesses, untabbed or end-tabbed, two specimen sizes are available (B1 and B2).
