Carbon-fibre-reinforced plastics. Determination of the size and aspect ratio of crushed objects
This International Standard specifies test methods for measurement of the size and aspect ratio of crushed carbon-fibre-reinforced plastics (CFRP), especially for recycling purpose. In this International Standard the shape of crushed CFRP, the fragment, is treated as a rectangular shape, and the measurement of the long and short sides of the shape is described. It applies to fragments of the following average dimensions:
length of the long side: 5Â mm to 50Â mm;
width of the short side: 1Â mm to 10Â mm.
This International Standard provides three measuring methods, two methods are manual methods using microscope and scale and the third method is an automatic method using a measuring apparatus.
Crushed CFRP obtained from thermosetting or thermoplastic resin matrices are covered by this International Standard.
NOTE If the crushed CFRP contain a lot of small fragments and fine particle, it is intended to screen out by a sieve of 1Â mm size before the measurement.
