Thermoplastic composites

Valokuva 100-prosettisesti biopohjaisesta biokomposiittituolista.

VTT brings composites from laboratory to production. The modern thermoplastic composites are future materials solutions for sustainable applications. These materials can be tailored for optimal performance.

Key facts

Modern thermoplastic composites are essential for saving energy and materials.

Biocomposites can be designed to be totally biobased, supporting the targets of bioeconomy.

VTT takes composite solutions from laboratory to production.

Our expertise in material handling and composite processing helps in fully utilising the benefits of the nanoeffect.

Sufficiency of materials and energy is one of the great challenges of today and the future. Light and sustainable products save both energy and materials. Here, modern thermoplastic composites are essential.  

Composite materials enable better performance and decreased material use. By using a proper composite designed for the application, the result is a lower material and energy consumption in total together with better performance.

High performance with nanocomposites

In a composite, the filler material and the matrix form a material combination with unique properties. The possibilities for composite design become more versatile when particle size of the filler is decreased to nanoscale bringing the so-called nanoeffect.  

Small particles tend to agglomerate, so to fully utilise the benefits of the nanoeffect you need expertise in material handling and composite processing. We have the methods to keep the desired particle size during compounding and product manufacturing, so the nanocomposite will have the designed functionalities. 

In the on-going European Commission funded project GRIDABLE we are creating electrical insulation systems based on nanocomposites. In this project, the nanoeffect provides enhanced dielectric properties which decrease losses in high-voltage power electronics.

Efficiency with biocomposites

Biocomposites can be tailored to meet numerous application requirements as well as the circular economy principles. Combination of natural fibres with thermoplastic polymers and processing technologies offers exciting new market opportunities for biocomposites. Raw materials for biocomposites, both the reinforcement and plastic matrix, can be derived from side streams or even waste streams. Biocomposites can be designed to be totally biobased, supporting the targets of bioeconomy.

Current research at VTT is focused on second generation biocomposites of different material combinations including bio-based polymers, materials from circular economy, additives, coupling agents, multilayers as well as foamed and extruded film composites. More recently plastic foaming and film extrusion has become one of the focus areas.

From laboratory to production scale

We provide a holistic service including the definition of the composite formulation, manufacturing of test material, and pre-production of prototypes. VTT brings new composites from laboratory to production scale together with our customer. Our deep understanding on material technology with our state-of-the-art equipment for material processing and analysis lets us create the required composite.
