20、orced moulding composite like SMC/BMC and GMT/LFT is their ability to carry even longer reinforcing fibres to all parts of the mould during compression moulding. This material flow causes fibre orientation in the moulding and as a consequence an anisotropy of the properties. To provide engineers wit
21、h suitable data for designing new mouldings the knowledge of the anisotropy received under defined moulding conditions is essential. In practice the mould coverage of those composites is in the range of 25 % to 30 % therefore the necessary test plates for preparing test specimens by machining needs
22、to be manufactured under comparable conditions. For both composites this supposition is fulfilled in their European Standards for the preparation of test plates to determine flowability. Therefore these test plates can also be used for the preparation of specimens for determining the anisotropy of t
23、he composites to be tested. No special procedure to manufacture test plates has to be given in this European Standard.

24、the preparation of specimens of compression moulding composites for determining the anisotropy induced by material flow. It is applicable to all SMC/BMC and GMT/LFT composites, which are being moulded under defined moulding conditions as described in EN ISO 12115 and ISO 1268-9. 2 Normative referenc
