Composite Truck Component Carrier from Lanxess Wins GKV/ TecPart Innovation Award
A truck component carrier made from a Lanxess (Cologne, Germany) polyamide 6 (PA6) compound has won the 2022 GKV/TecPart Innovation Award.
The structural component, jointly developed by BBP Kunststoffwerk Marbach Baier (Marbach am Neckar, Germany), Lanxess and an unnamed German commercial vehicle manufacturer is a Durethan BKV35H2.0 901510 PA6 compound reinforced with 35 weight percent short glass fibers.
“Our material and our comprehensive process and structural simulations have helped to ensure that the carrier does not have to be reinforced with heavy and expensive metal inserts, in contrast to a direct long fiber thermoplastic [DLFT] composite design variant based on polypropylene,” Dr. Matthias Theunissen, an expert in lightweight design in plastics application development at Lanxess, says.
“As a result, the component is around 35% lighter and much cheaper to manufacture.”
The component carrier is used in multiple truck models and takes the form of a trough with a cover. It is fastened to just four points at the center of the truck’s ladder frame and performs a number of tasks.
For example, it holds two batteries weighing 75 kilograms each, as well as three compressed-air tanks, each of which tips the scales at around 7 kilograms. The structural component is exposed to considerable acceleration forces of approximately 1.2 million kilometers over a vehicle service life.
These dynamic forces, plus the high weight of the entire assembly and the small number of fastening points, mean that it is subject to significant mechanical loads, Lanxess notes.
