A Heat Transfer Analysis of the Fiber Placement Composite Manufacturing Process

摘要: A computer code is developed to accurately simulate the three-dimensional heat transfer during thermoset fiber placement composite manufacturing process. The based on Lagrangian formulation of problem. Eight-node brick elements are employed, and 2 × integration rule used numerically evaluate integrals over an element. coupled ordinary differential equations obtained by semidiscrete problem integrated unconditionally stable backward difference method. validated comparing computed results for several problems with those available in literature. Composite rings manufactured continuously laying a tape cylindrical mandrel temperature histories at points measured thermocouples. distribution found compare well test findings. can be optimize processing variables.
