Lectures

Sensitivity analysis of an integrative simulation approach for short-fiber-reinforced plastics

An integrative simulation approach for injection-molded short fiber-reinforced plastics enables the consideration of process-induced morphologies like locally varying fiber orientations. The knowledge of these process-induced micromechanical characteristics is gained by conducting injection molding simulations and transferring them into structural Finite Element (FE) analyses in combination with corresponding mechanical material parameters. This combined approach is essential in order to obtain high quality FE analysis results.

Commonly, early stages of product development processes are characterized by a high degree of uncertainty. Often, detailed information about the injection molding process or about mechanical material parameters required for a comprehensive application of an integrative simulation chain are only partially or even not available. In this contribution, these uncertainties are focused by analyzing the impact of different parameter variations on the final structural simulation results.

Dr.-Ing. Jan-Martin Kaiser, Robert Bosch GmbH (D)

After graduating in production technology and mechatronics at the University of Saarland Jan-Martin Kaiser remained at the University as a research assistant.

In 2013 he received his doctorate on the subject of "contribution to the micromechanical calculation of short fiber reinforced plastics - deformation and failure" and with it he started his career at Robert Bosch GmbH as a research engineer in the Corporate Sector Research and Advance Engineering: Polymer Technology.

 

 

Comparison of practise with fill and warp simulation of plastic components

The decorative, dimensional and functional demands on plastic components are steadily increasing while the required time for the development and industrialization of the products is decreasing.

This results in less time for any optimization loops of the components.

In conclusion, a greater attention must be paid in the product development phase for an optimum degree of plastics-oriented design of the components. In order to evaluate which part geometry is the "better" one the simulation can be a great support.

Furthermore the simulation offers the possibility to estimate the impact of the tool on the product quality and the process.

The simulation tries to illustrate accurately reality by mathematical models etc. But because of material and process influences the results of simulation results cannot be transferred 1: 1 to reality.

How accurate simulation results are can be determined by comparison with real parts. This will be explained in the presentation on the example "air flow heat pump dryer".

Thermoforming of Organosheets and following Injetion molding of details - research of residual strain and warpage

Overmoulding of thermoplastic composites is a technology in which a thermoplastic composite is thermoformed and subsequently injection overmoulded. The near-net-shape manufacturing process is well suited for automated large series production of complex 3D structures with excellent structural performance and a high level of function integration. Although the feasibility of the process is increasingly demonstrated, it is acknowledged that there is a lack of proper design tools that can be used for a right-the-first-time design strategy. The COMPeTE project was established with the aim to create (numerical) design tools based on the basic mechanisms that underlay the overmoulding of thermoplastic composites using commercially available software packages. The work was carried out by the TPRC and funded by industrial partners from both the aerospace and automotive industry.

Establishing a bond between the resin and the insert requires intimate contact and healing of the two materials. Although intimate contact is a prerequisite for healing, the actual bond strength develops during the healing process in which polymer chains diffuse across the interface. The part, however, cools down rapidly during overmoulding to achieve short cycle times. This limits the available time for bonding and therefore makes the process more difficult. A test method was developed to characterise the bond strength under tensile and shear loading conditions. The characterized bond strength was used to develop numerical tools that predict the interface strength as a function of the injection moulding process characteristics.

An experimental method was developed for the analysis of warpage and spring-forward in single curved, overmoulded geometries. A thermo-elastic model was experimentally validated and subsequently implemented in a FE simulation, taking into account the fibre stresses and fibre reorientation resulting from the draping process. The methodology will finally be demonstrated using a three-dimensional, doubly curved C/PEEK part that was manufactured using the covermoulding process.

Thijs Donderwinkel, ThermoPlastic Composites Research Center (NL)

Thijs Donderwinkel studied mechanical engineering at the University of Twente in Enschede. During this period, he participated in the solar car racing team, where his interest for composite materials started. Further experiences with composite materials were obtained during his internship at Audi AG in Neckarsulm and his graduation project at the ThermoPlastic composite Research Center. Currently, he is a researcher at the ThermoPlastic composite Research Center. Together with industrial partners, a software tool is being developed to predict shape distortions during the overmolding process.

 

 

Autodesk Helius PFA - connecting the gap between process & FEA

Injection molded plastic parts are widely used in industrial applications due to their fast processing times and their ability to conform to a variety of geometries. Fiber reinforced plastics offer further benefits by offering enhanced stiffness-to-weight and strength-to-weight ratios.  Injection molding simulation software packages can be used to predict the warped shape of the ejected, room-temperature part, as well as the distribution of fiber orientation for filled materials. Both results can have effects on the mechanical properties of the part. Autodesk Helius PFA has been developed to leverage manufacturing data in standard structural FEA tools by mapping manufacturing data from Autodesk Moldflow simulations to structural meshes of varying element types and mesh densities. Please join us for a discussion on leveraging Autodesk Helius PFA for as-manufactured structural simulation of fiber reinforced plastics, including mapping manufacturing data from Moldflow to structural FEA, predicting orthotropic plasticity and rupture in tension and compression and predicting the strength of weld lines.
