FIELD: process engineering.
SUBSTANCE: invention relates to reinforcing materials, particularly, to intermediate material to be combined with thermosetting resin for production of composite parts. Intermediate material consists of unidirectional web of carbon fibres with surface density of 100-280 g/m2 bonded on every side with thin 0.5-50 mcm depth film of thermoplastic fibres. Note here that said intermediate material features total depth of 80-380 mcm.
EFFECT: satisfactory mechanical properties suitable for in, for example, aircraft engineering.
