| Abstract Scope |
Automated fiber placement (AFP) enhances production rates with consistency, lead-times, costs, and material yield compared to hand layup. However, AFP often generate scrap due to leftover materials in the creel and struggles with defects like puckers and wrinkles in highly contoured complex parts. To overcome these challenges, a hybrid of additive and fiber placement technologies called fiber patch placement (FPP) introduced for producing geometrically complex fiber composites and curvilinear reinforcements. This multi-robotic process enables a new degree of freedom in fiber deposition at a significantly higher rate. Upon completion of structural analysis and optimization that meets part requirements, design is transferred to software package for optimizing patch placement and generating tool path and numerical computer (NC) codes for robotics. Offline programming and simulation facilitate virtual manufacturing access. Leveraging high-performance robotics and technological advances, FPP aims to bridging the manufacturing requirements for production of geometrically complex fiber composite parts. This study presents manufacturing and modeling methodologies for engineer fiber patch placement parts, encompassing patch modeling, FPP properties integration into finite element models, and design analysis. It details FPP composite manufacturing and testing, evaluating strength knockdowns from fiber discontinuities in flat panels with various overlap lengths for design method development. Expanding on foundations and findings from finite element modelling the Open Hole Tension test coupons, validation extended to a cylindrical part with variable radii under compression testing. Test results closely matched analysis models, confirming the reliability of modeling tools in complex FPP design. |
