摘要: Abstract A model for wet filament winding of thermosetting matrix cylinders was developed. The relates the processing conditions (applied temperature, fiber tension and speed) to degree cure, volume fraction stresses strains within composite cylinder. In this work, modeling techniques behind predicting are described validated. Specifically, a motion developed which describes each layer cylinder during winding. This includes effects bed compacting as new is wound resin flow through porous bed. addition, several unique features were incorporated into model: stiffness evaluated function both cure state rule mixing high-viscosity with lower viscosity simulate bleeding from previously layers. Both must be included if position accurately predicted. Model predictions compared full-scale (1 m diameter) commercially cylinders. Tow tension, time sizing varied. There good agreement between experimental data. Several important trends in data observed: (1) low layers occur when one next long enough gelation; (2) even has not completely gelled, can bleed cause fraction; (3) increase overall by improving compaction characteristics.
