Replacement of metals and composites
Many applications call for materials with high strengths, while at the same time they have to be light – especially in the case of components subject to dynamic stress. Generally, properties such as low thermal expansion, high dimensional accuracy and long-term dimensional stability are additionally required.
We meet these demands with specially fibre-reinforced compounds – particularly through the use of carbon-fibre reinforcement. Examples here include the material classes of LUVOCOM XCF and LUVOCOM LW.
Carbon-fibre reinforced thermoplastics
Typical applications for carbon-fibre reinforced compounds are fast-moving components in the construction of machinery and apparatus – for example thread carriers, pump impellers, gear wheels, cams and connecting rods. In the automotive sector, hese materials are used in air and exhaust management, in vacuum pumps, steering units as well as in the drive train. In aviation, the low weight and the stiffness of carbon-fibre reinforced compounds open up countless opportunities in lightweight construction – examples include use for luggage racks and structural elements. As an alternative to aluminium in the fabrication of casings, carbon fibre reinforced materials have also proven their worth – and also for electromagnetic shielding (EMC).
LUVOCOM XCF - Outstanding mechanical properties
LUVOCOM® XCF offers flexural strengths of up to 530 MPa and tensile moduli of up to 52 GPa, as well as low thermal extension, improved thermal conductivity and high dimensional accuracy. As a result, it provides even greater scope for replacing metals and composite materials (CFRP and GFRP). LUVOCOM® XCF compounds are used for components subject to high mechanical requirements. The motivation for this is the reduction in weight and costs. Another approach is to substitute plastics with short and long glass-fibre reinforcement in applications where additional weight savings are required. Examples of such applications are lifts with high-performance motors or electric drive systems. Additional weight savings of up to 30% are possible with LUVOCOM® XCF compounds. Lower filler levels mean better processing characteristics and hence greater freedom in design. The materials can be processed in conventional injection moulding procedures without the need for special machines or techniques.
