FIELD: process engineering.
SUBSTANCE: invention relates to production of prepreg and prepreg-based materials. Proposed process comprises the feed of unilateral conducting fibres of definite width and bringing them in contact with resin first ply first surface including the thermosetting resin. Resin and fibres are compacting by forcing them under one or several impregnating rollers. Note here that pressure acting at conducting fibres and resin does not exceed 40 kg per conducting fibre width centimetre. The amount of resin should be sufficient for penetration in between fibres and for making of resin outer ply. The latter, in fact, does not contain unilateral conducting fibres. Besides, this invention relates to solidified composite laminate and solidified composite prepreg-based sheets produced as indicated above.
EFFECT: better resistance of breakage caused by thunderbolts.
