iOrganic sheets for injection moulding machines

JEC Europe 2012 - Lightweight construction is gaining attention – and not only in the automotive industry. Bumpers, fenders, roof, and car interiors – every kilo stripped is golden profit.

Less weight means more kilometres with the same battery charge or tank of gas. To better address the needs of this huge market, organic sheets can be used with resin laminated products.


Short fibres can be used in plastics, as well as glass mat reinforced thermoplastics (GMT) or organic sheets, as a flat support and finally inserted with continuous filament according to predetermined laying patterns. Weberit uses a virtual test station to simulate the working life of a plastic part and then determine where exactly to place the continuous filaments to provide the best effect where it is most needed. "Strength & force just in place." This means setting continuous filaments in the right place along the lines of force where they work during the product lifetime. This way, it is possible to shed further weight.


Weberit Werke Dräbing GmbH (Oberlahr, Germany) has developed a method whereby conventional glass mat thermoplastics (GMT) and organic sheets can be cost-effectively overmoulded with additional functional elements of reinforcing fibre strands.


With this new process (patent pending), fibre strands of different materials such as glass, carbon, aramid or basalt are inserted along the lines of force. This method provides much higher resistance than conventional short-fibre reinforced plastics and achieves higher stiffness and strength. This significantly facilitates industrial processing due to shorter cycle times.
