Simulation par ordinateurIndex. décimale : 668.4 Plastiques, vinyles Résumé : Most users of Automated Fibre Placement (AFP) equipment use the software provided by the machine vendor, which is simply not economical or realistic for manufacturers. This paper presents a universal AFP software program (Autodesk TruFiber) that allows manufacturers to select the best machine for the job. Additionally, case studies are used to expound the optimization of the kinematics parameters of the AFP process. Note de contenu : - Operation strategy

StratifiésIndex. décimale : 668.4 Plastiques, vinyles Résumé : An efficient expérimental method is proposed to measure the very low permeability of composite laminated preforms fabricated by automated dry fibre tape placement. A new computer program is also presented for the numerical simulation of three-dimensional resin flow, which is generally impossible using conventional commercial packages due to an extremely high computing cost.

Placement automatisé de fibresIndex. décimale : 620.19 Autres matériaux Résumé : Most users of Computer Numerically Controlled (CNC) Automated Fiber Placement (AFP) machinery use off-line Numerically Controlled (NC) programming software supplied by the machine builder. This machine builder-supplied software only works with their specific machine, forcing manufacturers to implement multiple off-line NC programming products when using multiple brands or vintages of machines. The more mature CNC metal-cutting industry started the same way, but has now evolved into a clear separation and cooperation between independent software and machine suppliers. This has freed the end-user company to select the best machine for the job, white using one universal software application to create NC programs for a variety of machine brands or vintage. When combined with composite design software tools that specifically take into account AFP manu¬facturing requirements early in the product development cycle, engineering and manufacturing specifications are seamlessly transferred to the manufacturing process. This paper discusses the implementation and use of machine-independent off-line NC programming software as it applies to CNC fiber placement machines.
