The application of the filament winding (FW) technique was extended for the purpose of substituting all the prevalently manual techniques, exploiting the advantages of this unique technology by placing the fibres along the geodetic lines of the structural surfaces to be created in order to obtain the maximum values of the mechanical characteristics and elastic properties of the composites. Design methodology and advanced methods of control extended to nonlinear field were developed, which take into account the anisotropy of the composite materials. A 3-dimensional computer aided design/computer aided manufacture (CAD/CAM) software is being developed to identify and handle any surface, even of complex geometric shape. A FW prototype machine is being developed with numerical control software able to cope with up to 5 interlocked axes, with the precision now obtainable by the electronic controls of numeric type.
-EXTEND THE APPLICATION OF THE F.W. TECHNIQUE FOR THE PURPOSE OF SUBSTITUTING ALL THE PREVALENTLY MANUAL TECHNIQUES,EXPLOITING THE ADVANTAGES OF THIS UNIQUE TECHNOLOGY BY PLACING THE FIBRES ALONG THE GEODETIC LINES OF THE STRUCTURAL SURFACES TO BE CREATED IN ORDER TO OBTAIN THE MAXIMUM VALUES OF THE MECHANICAL CHARACTERISTICS AND ELASTIC PROPERTIES OF THE COMPOSITES.
-DEVELOP DESIGN METHODOLOGY AND ADVANCED METHODS OF CONTROL EXTENDED TO NON-LINEAR FIELD,WHICH TAKE INTO ACCOUNT THE ANISOTROPY OF THE COMPOSITE MATERIALS.
-DEVELOP A THREE-DIMENSIONAL CAD/CAM SOFTWARE TO IDENTIFY AND HANDLE ANY SURFACE,EVEN OF COMPLEX GEOMETRIC SHAPE.
-DEVELOP AND CONSTRUCT F.W. PROTOTYPE MACHINE WITH NUMERICAL CONTROL SOFTWARE ABLE TO COPE WITH UP TO 5 INTERLOCKED AXES,WITH THE PRECISION NOW OBTAINABLE BY THE ELECTRONIC CONTROLS OF NUMERIC TYPE.
-DEVELOP AND REALIZE THE DESIGN OF A PROTOTYPE PRODUCTION PLANT UTILIZING F.W. MACHINES COMPLETELY CONTROLLED FROM A CENTRAL AUTOMATIC STATION.
-CONTROL THE FIBRE-MATRIX RATIO IN ACCORDANCE WITH THE LANMINATE REQUIREMENTS.
-DEVELOP TECHNOLOGIES WHICH WOULD BE CAPABLE OF EXTENDING THE UTILIZATION OF F.W. TECHNIQUES.FOR EXAMPLE,CHECKING OF FIBRE-MATRIX RATIO IN WET IMPREGNATION,THE CREATION OF LOW-COST PRE-IMPREGNATED WITHOUT 'GREENLIFE' PROBLEMS,THE CONSTANT CONTROL OF THE BUNDLE WITH OF DEPOSITED FIBRES.
-PREPARE AND EXPERIMENT VALID HYPOTHESIS OF FAILURE AS WELL AS METHODS OF PREDICTING DAMAGE PROPAGATION.
