EMBROIDERY is a collaborative Project co-funded by the 7th Framework Programme of the European Community. Further information on European Community research programmes can be found on the Cordis web site.
Composite materials are starting to be used extensively in many industrial applications (automotive, rail, aeronautic, marine, wind energy, construction, etc) with higher production needs than the yielded by current manufacturing technologies. This partially hinders a higher widespread.
New developments such as textile preforming combined with liquid moulding technologies offer the possibility of introduce a real automation approach to the composite manufacturing. Nevertheless, there are still some drawbacks.
The approach to be investigated in EMBROIDERY is the development of a resistive self heated layer able to be embedded within either rigid composite laminates of elastomeric materials for membranes manufacturing. This heating layer will by manufactured by meand of Tailored Fibre Placement (TFP) technology. This will bring the following benefits:
In addition, TFP provides an outstanding capability to the composites industry, the fibre steering potential. That means that in the preform, the fibre orientation at each point can be oriented according to the stress field of the component, exploiting the full capabilities of the reinforcing fibre and optimising the material usage. However, in practice this potential is not exploited yet due to the lack of a computer commercial software package which takes into account the fibre steering feature. Therefore, a second focus of this project will be put on developing computer algorithms which account for steering potential. The final objective is the implementation of such algorithms into a commercial software for composites analysis.
A third focus of the research will be put on the automation of the Tailored Fibre Placement Tecnology itself. TFP has been developed in the mid 90s and is based on embroidery machinery used in the garment textile industry. The machines have been adapted to deposit and stitch fibre rovings onto a base material. However, being a relatively new technology and coming from the conventional textile industry, it is necessary to improve and adapt the process and equipment to the specific requirements of the advanced composites industry manufacturing.
