Design And Implementation Of Experimental Equipment For Studying Processing Parameters Of Composite Tape Laying

Composites have been used more and more widely in the vehicle, ships, aerospace andothers industries due to their advantages of light weight, high strength, fatigue and corrosionresistance. The consumption of the composites in the aviation parts has become an importantsymbol to measure the advance of an aircraft. It is to be more important how to ensure thereliability and stability of the composite parts quality in automatic production along with thedevelopment and innovation of the automatic production equipments of the composite parts.For the application of the composite prepreg automatic laying molding technology, theprocessing parameters influence on the prepreg laying quality is analyzed in this thesis.Experimental equipment is designed to provide an experimental platform for the followingresearch of the influence of laying processing parameters on the laying quality and theoptimization of the automated laying processing. The major study contents of the thesis are:First, the influences of processing parameters on the layer deformation and layers pasteintensity are analyzed for the epoxy prepreg. Main functions of the experimental equipmentconsist of laying velocity, roller force and heating temperature. The mechanical systemstructure is completed on the foregoing basis.Secondly, by analyzing the technical requirements of the control functions, the layingvelocity hardware system basing on servo drive system, heating control hardware systembasing on PID control and roller force control system comprising of stepping motor, elasticrobber roller and pressure sensor are designed. The hardware system of the experimentalequipment is completed.Thirdly, laying velocity control program, roller force closed-loop control program andPID temperature control module program are designed using the FP0R series controller as thecontrol core combining with the module unit FP0-A21. Human-computer interaction interfaceis designed by using editing software EB8000and TK6070iH programmable touch screen.Finally, the rationality and validity of the equipment is verified by using onlinemonitoring function to collect processing data of the laying experiment process.
