ROBOTIC CARBON FIBER WEAVING
UPenn Design Studio 2022.11-2022.12
Site: 640 Waterworks Dr, Philadelphia, PA 19130, United States
Instructor: Ezio Blasetti Co-Instructors: Sophia O'Neill, June Yuan
Collaborators: Matthew Ward, Yidan Wang, Yinglei Chen, Sihan Li
Contribution: Conceptual design, development, drawings, robotics scripting, and fabrication
Overall, for this project we only weaved 2D triangles. Given the simple task of this style of weaving, we were able to explore multiple jig assemblies that led to high-production weaving sessions. Jigs were constructed from aluminum bars with 35 points for threaded rods to be inserted as winding posts. The jigs were double sided and we were able to weave up to 10 layers of triangles per weave.
Structural Analysis
As we move closer towards our prototype geometry we assessed the structural performance in multiple ways. First we compared a single tetrahedron under a distributed load versus multiple subdivision arrangements at 2/3 and 1/3 scaling. Below we have arranged visuals of deflection, bending moment and principal stress analyses. As a group we were interested in being able to produce spans of carbon fiber and cantilevered sections under load. Highlighted here are some assessments of these structures arranged as a simple bridge and long cantilever of aggregated and 2/3 and 1/3 scaled tetrahedrons. This analysis is performed as a single closed mesh surface in all cases. In the deflection analysis red obviously represents areas of higher defl ection and higher concentrations of bending moments and stress. Digital Structural Simulation of Component & Algorithmic Assemblies minimum is the structural analysis for studio (part/whole) better do the analysis for each item in the small catalog above
