Christian Doppler Laboratory – cost estimation for efficient composite production

Christian Doppler Labor

Cost estimation for efficient composite production

Fiber-reinforced plastics or composite materials have exceptional mechanical properties due to their material combination of high-strength fibers embedded in a resilient polymer matrix. This makes them especially preferable for aerospace and racing applications. But also automotive, transportation, wind energy and sports industry can profit from this materials class’s performance.

But therefor, it is necessary to understand and be able to control the comparatively high material and manufacturing costs of composites. The key to this is cost modelling and estimation for which there are three basic principles available - analogous, parametric and bottom-up. Based on analyzation of these methods and known models a bottom-up/parametric hybrid approach was chosen for the development of the Christian Doppler Laboratory (CDL) cost estimation program ALPHA.

This research is made possible by the Austrian Federal Ministry of Science, Research and Economy, the Christian Doppler Research Association and FACC Operations GmbH.

In aircraft manufacturing, fiber-reinforced polymer composites have an enormous potential for fuel savings or increase in range and payload due to their better mass / stiffness ratio compared to metals. Currently, however, the aircraft industry is still heavily influenced by manual activities; this is where Evolution#4 comes in: Based on the Resin Transfer Molding process with integrated quality control as well as concepts of the digital twin, the aerospace sector is to be made fit for Industry 4.0.

Liquid Composite Moulding - Development and understanding by Research

Liquid Composite Moulding

Development and understanding by Research

The processing of composite materials using liquid composite moulding (LCM) has boomed over the last years. This is based on the possibility to automate the process, which is the basis for high volume production. Due to the high interest of the economy on this topic there are a few projects going on at the chair of composite processing. They are dealing with different problems of the LCM process.

Funded by the Ministry for Transport, Innovation and Technology (BMVIT) under the program “Produktion der Zukunft”.

HybridRTM – Quality assured processing technique for material hybrid composites using RTM

HybridRTM

Quality assured processing technique for material hybrid composites using RTM

In the project “HybridRTM” a one-shot resin transfer molding process is aimed in which the dry fiber based reinforcing structure and a metallic component are placed in the cavity. Infiltration and joining are done in once. Definition of resin injection point and venting gates is ­necessary. Furthermore, the processing conditions dependent curing and resulting residual stresses are of interest. The aim is to define optimized processing conditions resulting in highest adhesion between composite and metallic component, minimized distortion of the resulting component, and a short cycle time.

Funded by the FFG in frame of research and technology funding under the program “Produktion der Zukunft”, grant agreement no 848666.

Duration: 2015 - 2018

InP4 - "In-Line Process Control for TP Placement Process"

Projekt InP4: Steuerungstechnik für automatisiertes Tapelegen ©Kunststofftechnik Leoben

Tape placement technologies have been commercially used since 1980's, but the optimization potential has not yet been exhausted. The Processing of Composite Group is working on an in-line process control that will allow in situ consolidation and a stabilization of the process. The group uses a modular, custom-made placement system with a flashlight lamp system.

MoVeTech – Model-based processing technique for manufacturing of structural components in aerospace

MoVeTech

Model-based processing technique for manufacturing of high quality structural components in aerospace

“MoVeTech” is a project that involves modelling and simulation for composites in aerospace application and it is massively based on sensor assistance. In this project the Advanced Resin Transfer Molding process (also known as gap impregnation process) is analysed. This process is characterized by a gap between the preform and the upper mold. The resin is injected into this gap and afterwards infiltrated into the preform by fully closing the cavity. Different types of sensors (like temperature, pressure, DC or DEA) are used, which provide important processing information like flow front arrival, cure degree and resin crosslinking behavior.

Funded by the FFG in frame of research and technology funding under the program TAKE OFF, grant agreement no 850466.

NovoTube - flexible manufactured tubular structures

NovoTube

"NovoTube", the follow-up project of SCT - Smart Composite Tubes, addresses an alternative approach to decrease filling times and to extend process-related limitations in BARTM. A cascade injection procedure is implemented with the aim of considerably reducing flow lengths during preform saturation.

Funded by Ministry for Transport, Innovation and Technology (BMVIT) and the Austrian Research Promotion Agency (FFG) in frame of the programs “Intelligent Production” and “Production of the Future”.

RSBC - Reliable and Sustainable composite production for Biobased Components

RSBC - Reliable and Sustainable composite production for Biobased Components

The project "RSBC" focuses on the development and processing of renewable raw materials based thermoset matrix system for natural fiber reinforced plastics (NFRP)

The goals are the optimization of the material properties, the increase of the biobased carbon content insidethe thermoset system, and the reduction of ecologically and toxicologically harmful contents and excipients. Coordination of both components in the biobased NFRP material and process control contribute to the improvement and adjustments of the material properties for light and structural construction applications. The use of process monitoring methods completes the holistic approach for the prospective successful integration of biobased composites into industrial production processes.

Within the framework of a Life Cylce Analysis, the assessment of material and production processes is carried out under ecological and economic aspects and the analysis of the potential for use of the developed biobased fiber composite materials.

The project is funded by the FFG with funds from the research and technology support within the framework of the FTI Initiative: "Produktion der Zukunft", project number 858688.

SCT - Smart Composite Tubes: Automated Production of spatially curved fiber composite tubes

[Translate to Englisch:] SCT Smart Composite Tube

SCT – Smart Composite Tubes

Automated Production of spatially curved fiber composite tubes

A decisive criterion to meet the growing demand for composite materials in industrial applications is the development of highly efficient manufacturing processes. Here, bladder-assisted resin transfer molding (BARTM) represents a suitable process technology for the production of complex shaped hollow parts such as load-bearing frame structures or fluid piping elements.

In frame of the completed research project “Smart Composite Tube”, basic aspects for the realization of a flexible series production of curved composite tubes using braided fiber reinforcements and thermoset resins were studied.

Funded by the FFG in frame of research and technology funding under the program Intelligent Production, grant agreement no 838826.

Stellar – Selective Tape-Laying for Cost-Effective Manufacturing of Optimised Multi-Material Components

Stellar

Selective Tape-Laying for Cost-Effective Manufacturing of Optimised Multi-Material Components

The application fields for fiber reinforced composites are more diverse than ever before. Typically the reinforcing materials are based on carbon or glass fibers arranged into technical textiles. In case of high performance components a defined oriented reinforcement is required. Such structures can be reached by using unidirectional reinforced tapes and according placement technologies.

The aim of the “STELLAR” (Selective Tape-Laying for Cost-­Effective Manufacturing of Optimised Multi-Material Components) project was to develop a placement technology for thermoplastic based structures. The project was intended to develop a manufacturing process that is appropriate for a wide range of potential applications. 

Funded by the European Union Seventh Framework Programme [FP7-2013-NMP-ICT-FOF(RTD)] under grant agreement no 609121.
