Tape <strong>sandwich</strong> <strong>process</strong><br />

Enabler for sustainable products<br />

ENGEL and KTM Technologies developed a new <strong>process</strong> to produce a thermoplastic <strong>sandwich</strong> structure with<br />

endless fibres at the outer skins. A motorbike <strong>seat</strong> bench was manufactured as the first product using this<br />

technology. The <strong>process</strong> uses thermoplastic endless fibre <strong>tape</strong>s on top and bottom of a <strong>base</strong> material where<br />

the reinforcement has the highest impact on the structural properties. That’s why the amount of fibre <strong>tape</strong>s<br />

can be reduced to a minimum compared to a homogeneous reinforcement in the part. To keep the <strong>tape</strong>s on<br />

the mould surface a special mould technology was developed which fixates the <strong>tape</strong>s at the edge area and<br />

at the corners by using vacuum. Optimised <strong>process</strong> parameters during the injection moulding <strong>process</strong> ensure<br />

that the <strong>tape</strong>s are materially coherent joined to the injection moulded core.<br />

Due to the specific mechanical properties of the <strong>sandwich</strong> structure, the stiffness required for <strong>motorcycle</strong> <strong>seat</strong><br />

<strong>base</strong>s can be realized with a single-layer UD-<strong>tape</strong>. This means that the <strong>tape</strong> <strong>sandwich</strong> <strong>process</strong> requires significantly<br />

less energy and simpler production cell technology than conventional fibre-reinforced plastic composite<br />

<strong>process</strong>ing methods. With this new <strong>process</strong> it is possible to reduce the wall thickness (up to 75%), the design<br />

space needed (up to 66%) and the weight (23%) of the part with at least the same stiffness. This consequently<br />

leads to a reduction of the CO 2<br />

-Footprint (less material, less energy) and to a realistic recycling-scenario<br />

(single grade thermoplastic) at EOL. Do you have further questions concerning the <strong>tape</strong> <strong>sandwich</strong> <strong>process</strong> or<br />

would you like to discuss a specific project? We will be happy to advise you!<br />
