Automation of Sorting and Kitting from cutting tables

Broetje-Automation GmbH-Erik Berg
  • Technical Paper
  • 2019-01-1899
To be published on 2019-09-16 by SAE International in United States
Within the current part production of carbon fiber parts a lot of manual work is included for sorting and kitting of automatic cut plies. This is required due to the high raw material costs and enables a good utilization of the materials. Automation of this non-value adding process will be a big benefit for the part production. The high variety of shapes and the different materials to be processed are complex boundary conditions, which are to be overcome. Broetje is in development of handling systems and automation solutions, which are used for a high variety of materials as well as for a high variety of shapes. These systems are meant to be an add-on for existing cutting tables as well as for fully integrated production systems with downstream automation equipment like draping hoods. Mayor challenges to overcome are safe gripping capabilities, detection of #non-cut fibers, high variety of shapes, complex logistic management. These challenges are addressed with Broetje’s ASK Solution. This paper will focus on the innovative automated sorting and kitting solution invented by Broetje-Automation.
 

Development Of Multi-Material Overhead Stowage Systems For Commercial Aircrafts By Using New Design and Production Methods

The relevance of innovative and functional lightweight components for aircrafts has risen significantly during the recent years. In this context, modern lightweight materials as well as cost-efficient and time-saving manufacturing technologies are required for a future aircraft production. The so called Hybrid SMC Technology and the SMC-Foam-Sandwich Technology are promising approaches for the cost-efficient and time-saving manufacturing of lightweight, geometrically complex and functional aircraft components. Both technologies have been used for the development of a new generation overhead stowage system. It is realized by sidewalls made out of enhanced SMC technologies with directly implemented metallic load introduction elements and regular sandwich structures that can be assembled by a quick-assembly principle. Due to the glass fibers in the shape of chopped long fibers with no predominant direction in SMC material, continuous carbon fiber tailored fiber placement (TFP) fabrics were integrated to increase mechanical properties. Because of several load introduction points in the demonstration part, carbon fiber loops are a good and efficient possibility to transfer these loads. The challenge in the virtual design process of SMC…

Heat Transfer Enhancement in Stagnation Region of Aero-Engine Inlet Vanes due to Ejection Slot and Anisotropic Heat Conduction

Published 2019-06-10 by SAE International in United States
Ice protection is important for aero-engine induction system, such as the inlet vanes. For the ice protection of such parts manufactured with low thermal conductivity polymer-based composite material, the combined heating method using interior jet impingement and exterior ejection film has certain advantages. The simulation model coupling CFD with solid heat conduction was developed and solved with the anisotropic thermal conductivities model to investigate the heat transfer enhancement in the stagnation region of aero-engine inlet vanes due to ejection slot and anisotropic heat conduction, which is related to the curved geometry, ejection slots and anisotropic heat conduction.The temperature distribution and heat flux ratio between the stagnation region on outside surface and the impingement region inside were calculated and analyzed for the configuration with different ejection angle and different materials. The results show that ejection slots and anisotropic heat conduction plays important roles of the heat transfer process. For the same ejection angles, the larger the thermal conductivity, the higher the temperature at stagnation point and the better ice protection. For the same material property, the…

Design of Lightweight Fibrous Vibration Damping Treatments to Achieve Optimal Performance in Realistic Applications

3M Company-Thomas Herdtle
Herrick Laboratories, Purdue University-Yutong Xue, J Stuart Bolton
Published 2019-06-05 by SAE International in United States
In recent work, it has been shown that conventional sound absorbing materials (e.g., lightweight fibrous media) can provide structural damping when placed adjacent to vibrating structures, including infinite panels, partially-constrained panels and periodically-supported panels typical of aircraft structures. Thus, a fibrous layer may serve two functions at once: absorption of airborne sound and the reduction of structure-borne vibration. It has also been found that the damping is primarily effective below the critical frequency of the structure, and that the damping results from viscous interaction between the fibrous layer and the evanescent near-field of the panel, in the region where incompressible flow caused by the panel vibration oscillates primarily parallel with the panel surface. By using a near-field damping (NFD) model based on the Biot model for acoustical porous media, it has been shown that a properly-optimized fibrous layer can provide levels of damping comparable with those provided by conventional, constrained-layer, visco-elastic, damping treatments. Based on the idea that vibrating structures exhibit a certain wavenumber/frequency response spectrum, the focus of the current study has been on…

A step-change in the cost of CFRP

Automotive Engineering: May 2019

Published 2019-05-01 by SAE International in United States

Williams Advanced Engineering reveals secrets behind its innovations aim to move carbon fiber into the mobility mainstream.

A joke in the auto industry about CFRP (carbon fiber reinforced polymer) is that the “C” stands for “costly.” So, any manufacturing process that solves this significant drawback of the ultra-lightweight material's use outside of Formula One racing and exotic supercars, could change the vehicle-production game.
