Study Of Automatic Tape Placement Process And Stacking Design For Fiber Reinforced Thermoplastic Composites

Thermoplastic composites are increasingly replacing traditional engineering materials and are increasingly demanding in terms of productivity in areas where high productivity is required. To meet these requirements, we must achieve lower cost manufacturing while ensuring the quality of the production. Composite material automatic laying technology is one of the few that can achieve thermoplastic composite materials in large industrial applications for continuous processing technology, so the composite material automatic placement technology has become a hot research at home and abroad.This paper set up the automatic tape placement system to achieve the fiber reinforced thermoplastic composite material automatic laying function.Combined with the three-axis movement platform to complete the experimental platform of the mechanical structure design. Using Siemens 1200PLC controller to achieve the automation of the processOn the basis of the experiment platform, the experimental design of the continuous glass fiber reinforced polypropylene was carried out in combination with the design expert design software. The influence of the several main parameters of the laying process- temperature, laying pressure and laying speed ,on the mechanical properties and deformation degree of the laying products were studied and analyzed. The optimization of the processing parameters were carried out to obtain the optimal combination of the processing parameters of the continuous glass fiber reinforced polypropylene.Based on the optimization of process parameters, the influence of laying angle and layer number on the mechanical properties of the laying products was studied under the optimal parameters. The effects of 0°, 0°/±45° and 0°/90° on the mechanical properties of the laying products were analyzed. The effects of different layer numbers on the mechanical properties of the laying products were studied. The optimized design of the continuous glass fiber reinforced polypropylene was carried out by using the genetic algorithm, and the optimized combination of the ply design was the best.
