Long-fibre composite has high impact performance

Verton AF composites provide high impact performance with exceptional stiffness, high-quality surface finish and paintability.
Verton AF composites, a new series of long glass-fibre-reinforced ABS composites, made using GE Plastics Cycolac resin technology and LNP's patented Verton pultrusion process, provide high impact performance with exceptional stiffness, high-quality surface finish and paintability, and are targeted toward applications in heavy truck and off-road equipment, automotive interiors, furniture and sporting equipment.
Manfred Bar, European Business Leader Verton, explains the benefits of the new long-glass-reinforced Verton AF series composites: "The combination of high impact performance and exceptional stiffness allows the design engineer to develop thinner wall components.
This reduces part mass without sacrificing modulus or impact performance".
According to Bar, a 30% long-glass-reinforced Verton AF composite provides 48% higher stiffness than a 30% long-glass-reinforced polypropylene, and 14% higher stiffness than 40% long-glass-reinforced polypropylene.
He added: "Impact performance is equivalent to 30% long-glass-reinforced polypropylene".
Verton AF series composites also provide exceptional dimensional stability.
While most LFRT composites inherently provide good dimensional control due to the random fibre orientation, Verton AF series composites exhibit very low shrinkage in both the flow and transverse directions.
The material exhibits about half the shrinkage of LGF PP, which in the end will result in tight tolerance and very flat parts.
Additional benefits of the new long-glass-reinforced composites based on Cycolac technology include excellent transverse mechanical properties, low coefficient of linear thermal expansion (CLTE) and paintability.
In addition, a resin-rich surface is obtained due to exceptional fibre wet out - a benefit of LNP's Verton pultrusion process.
A unique portfolio of benefits make Verton AF composites strong candidates for structural body panels and housings requiring good dimensional control, high impact performance and good aesthetics.
Potential applications include instrument panel substrates, structural support frames for furniture, and structural body panels and housings.
