Abstract Scope |
Creating realistic tow geometries is an important step when modeling composite textiles. Obtaining the tow geometry from manufacturing simulations can be difficult due to the need to model the complex geometry of a tow consisting of many fibers with less for computational efficiency. A method for introducing fiber entanglement to the tows of a textile model has been developed and previously used to show how the compaction response of the textile can be controlled by the amount of entanglement introduced. The entanglement restricts the ability of the fibers to flatten out with less resistance than identified during experimental testing. This fiber entanglement method was utilized with a model of a single plain weave textile being dry compacted using the commercial finite element solver LS DYNA and the United States Air Force Research Lab’s VTMS solver. The predictions from this model were compared to experimental results collected by compacting a single ply of a dry plain woven textile. After the textile was compacted, the tow geometry was measured through the microscopy of cross-sections of the compacted textile. The predictions from the model are compared to the textile thickness, fiber volume fraction, and tow width, height and spacing observed from the textile compacted experimentally at different pressures. |
