<p>Unidirectional webs of discontinuous carbon fibres having a distribution of length such that the average length of the fibres, i.e. the average length of 50 % of the fibres of a sample is between about 40 and 70 % of the length of the longest fibre in the sample, the fibres being assembled with a resin or an adhesive with a fugitive nature. Unidirectional web of carbon fibres in which the carbon fibres are discontinuous, have a distribution of length such that the average length of the fibres, i.e. the average length of 50 % of the fibres in a sample, is 40-70 % of the length of the longest fibre in the sample, and the fibres are assembled using a resin or an adhesive with a fugitive nature.</p> |
