In simpler terms personal data is any information about you that enables you to be identified. Since SMC material properties are so dependent on manufacturing, a simulation tool was required to help design engineers quickly and easily predict local properties.Personal data is defined by the General Data Protection Regulation (EU Regulation 2016/679) (the “GDPR”) as ‘any information relating to an identifiable person who can be directly or indirectly identified in particular by reference to an identifier’. This module is designed for the early design phase when engineering departments need to evaluate or iterate on new designs quickly. To address this problem, we introduced a new module for SMC in ESI PAM-COMPOSITES 2020. These properties depend highly on how the fibers will reorganize (location, orientation, and density) during material compression. The biggest challenge with SMC is predicting and controlling local material properties of the produced part upfront in the product development process.

It is a proven technology for the manufacturing of net-shape (without post operations) performant parts in large production series at a very competitive cost. Sheet Molding Compound (SMC) is a multi-purpose lightweight solution, easily molded into complex shapes, allowing for the replacement of many metallic parts by one or a few SMC parts. This robust modeling capability is required to capture how the resin flows through the thickness and to identify risks for internal dry zones. The capacity to treat very small to huge models made of solid elements is unique to PAM-RTM. These large numerical models are frequent in the wind industry because of the size of the components and the automotive industry because of the detailed geometry requiring small element size. However, it can also use accurate fiber orientations computed in a PAM-FORM performing simulation.ĭue to its unique, high-performance DMP solver, PAM-RTM can handle large numerical models using shell or solid elements. Use geometrical approaches to approximate the orientations of the fibers in the preform. Permeability depends highly on fiber orientations, making it essential to account for these fiber orientations in the injection/infusion process simulation.

This approach minimizes design margins and improves weight reduction.Ī key parameter of Liquid Composites Molding (LCM) simulation is the permeability of the preform's reinforcements. Once the process chain is optimized to meet product tolerances, results are easily transferred to the design department for an “as-built” instead of “as-designed” structural analysis. This ensures maximum feedback accuracy when adjusting the process parameters to correct defects and reduce production cycle time. Material information and history (local shearing, local fiber content, and orientation, degree of cure, etc.), as well as geometrical properties (shape, thickness, etc.), are seamlessly transferred from one stage of the manufacturing chain to the next. With the unique capabilities of ESI PAM-COMPOSITES, you can study each step of the composites manufacturing chain through a process-oriented workflow.

Often, this calls for quick iteration and sometimes a new approach to material configuration and process parameters.
