Parameters stamping process

However, to check the forming behaviour of 3D warp interlock made with commingled yams, using such a complex final preform as represented in Figure 10.6, a first approach is applied on different fabric parameters and forming shapes to find the best adapted architecture to the stamping process. 

Like HAZOP, STPA works on a model of the system and has guidewords to assist in the analysis, but because in STAMP accidents are seen as resulting from inadequate control, the model used is a functional control diagram rather than a physical component diagram. In addition, the set of guidewoids is based on lack of control rather than physical parameter deviations. While engineering expertise is still required, guidance is provided for the STPA process to provide some assurance of completeness in the analysis. 

Important Process Parameters Glue Deposition The glue can be deposited by different methods, such as dispensing or another kind of transfer, e.g., stamping with a spin-coated substrate or a dedicated intermediate stamp. 

Fineblanking, often referred to as precision stamping, is a cold metal extrusion process which produces highly accurate components. Fineblanking is a manufacturing process that involves special type of presses and of tooling. The system is a function of the following parameters ... 

With regard to methods of fabrication, all processes in Table 1.1 that are applicable to unfilled, unmodified thermoplastics can also be used for discontinuous systems (with the exception of expandable bead molding). In addition to thermoforming, hot stamping of reinforced thermoplastic sheets mostly containing randomly oriented continuous or discontinuous fibers is used for the production of large semistructural parts. Fillers can also be used in the thermoset processes in Table 1.1, often in combination with the primary continuous fiber reinforcement. The content and inherent properties of the additive, as well as its physical/chemical interactions with the matrix, are important parameters controlling the processability of the composite.
