Performance Research

ctw/pt

Performance of Advanced Materials involves a better understanding of the mechanics of new materials, focusing on the physical properties of the component and mostly linked to their production process.

An increasing range of properties is being considered, from thermomechanical properties such as stiffness and structural integrity, to optical and electromagnetic properties on the short and the long term. Materials with ‘added functionality’ (e.g. composite with integrated sensors and actuators or even self-healing capacity) receive growing interest are treated separately. The current research projects in this theme are listed below.

STIFFPACT

Impact damage control in thermoplastic butt-joint stiffened panels

 2011-2013

The increase use of thermoplastic in (semi) structural composite constructions leads to specific skin-stiffener technologies, like the co-consolidated butt-joint developed by Fokker. This project aims at defining design rules for these joints under the specific impact loading condition.

Gert Jan NevenzelIn collaboration with the Catalytic Processes & Materials group
In TRANSFORCE the CPM group develops a technique to grow Nano Carbon fibres on Micro Carbon Fibres. The PT group characterises the improvement of properties transverse to the fibre reinforcement. Aim is to find an optimum between formability and performance.

Optimisation of the Laser Assisted Tape Placement Technology

2008-2012

Staff

Wouter Grouve

In this part of EcoDesign, the Laser Assisted Tape Placement technique, where a Thermoplastic composite tape is layed on a thermoplastic composite substrate, is optimized for performance, and ultimately to reach in-situ consolidation. Though this project is basically concerned with the optimization of the process parameter, the link with obtained performance is evident.

EUREKA High Pressure Reinforced Pipes

2001-2006

Staff

Maarten Kruijer

Steel Reinforced Thermoplastic Pipe (s-RTP) is a new class of pipe offering the benefits of PE at pressures up to 150 bar (5inch pipe). Continuous pipe of up to 400m can be produced. The time dependent deformation and failure behaviour of this kind of pipe is modeled and validated in this project, leading a design strategy.
