A METHOD OF LAYERED LAMINATION OF A CONSTRUCTIONAL ELEMENT WITH AN UNIFORM AND/OR HYBRID FIBRE-POLYMER COMPOSITE IN AN IN-SITU METHOD BY THE USE OF ULTRASONIC VIBRATION IN A CONTINUOUS PROCESS AND A DEVICE FOR THE REALIZATION OF THE METHOD

摘要

Subject matter of the invention is a method of manufacturing of a layered composite laminate for use as a reinforcement of a constructional element characterised in that the application of layered composite laminate on the surface and/or the place of the treated constructional element occurs in situ in a continuous process by the use of ultrasonic vibration; whereupon the initially prepared constructional element is put in a feed motion and next it is subjected to the process of layered composite lamination comprising of at least three stages: shuffling stage, where to a shuffling head where to a shuffling head in front of at least one shuffling element, simultaneously fibre materials (roving materials) and/or additional fibre materials are conveyed from bobbin creels and to the interior of each shuffling element via inflow opening (4) a polymer matrix is conveyed through ducts in a one-, two- or multicomponent system from a container by means of a pump of a total efficiency in weight relation to the fibre material from 0,8:1 to 1,2:1; as a result of shoving the constructional element the fibre material being layered interleaved and simultaneously soaked with polymer matrix, passing through the shuffling head that is sliding over the constructional element [the fibre material] is laid on the surface and/or in the place of the constructional element; sonication stage, where by means of a sonotrode of a width of at least equal to the width of the applied laminate and of a power from 5 to 500 W/cm² pressing and mixing of all the components of polymer matrix takes place in a time from 2 to 10 sec, through sliding of the sonotrode at the place on the constructional element where earlier the fibre material has been layered laid and soaked with polymer matrix /at the place of the earlier layered laid fibre material soaked with polymer matrix on the constructional element; crosslinking stage during which the layered laid fibre material soaked with polymer matrix and being on the constructional element after the sonication stage is submitted to thermal treatment of hardening in an oven, in a temperature range from 50 to 180°C; to the moment of reaching the desired level of hardening and maximum thermal resistance from 2 to 6hrs. Subject matter of the invention is a device for the realization of that method.
