LANXESS subsidiary Bond-Laminates Promotes Thermoplastic Composites for Mass Production

Cologne – LANXESS subsidiary Bond-Laminates will be attending the JEC World Composites Show & Conference 2018 in Paris. The event is said to be the leading trade fair for the global composite industry. “We are one of the few developers and manufacturers of continuous fiber-reinforced thermoplastic composites worldwide offering a wide range of tailor-made composites for mass production. Our focus of this year’s presentation at the JEC is on mass-production applications of our Tepex brand composites in the automotive, consumer electronics and sports sectors,” explains Dr. Dirk Bonefeld, head of Marketing and Sales at Bond-Laminates. “Other focal points are new processing technologies for thermoplastic composites and our ‘HiAnt’ customer service.”

In cooperation with manufacturers of plastics machinery and automation technology, Bond-Laminates has succeeded in developing new processing technologies that go far beyond the thermoforming of Tepex semi-finished products. Bonefeld: “We see ourselves as pioneers of new processing methods that extend the application potential of our composites and increase the performance and functionality of the corresponding components.” One example of this competence is hybrid molding. This one-shot-process makes it possible to shape a composite semi-finished product in the injection mold, to reinforce it at selected points with short-glass fiber-reinforced thermoplastics and to provide it with additional functions such as fixings and guides. As Bonefeld reports, “Hybrid molding has meanwhile proven itself in the series production of numerous lightweight automotive components such as seat shells, bumper beams, brake pedals and module carriers.” Another example of Bond-Laminates’ technological expertise is a hybrid finishing process for the production of decorated lightweight components. It combines hybrid molding with IMD (In-Mold Decoration) technology and enables fully automatic mass production, without any reworking, of lightweight components with high-quality surface decoration. “We aim at extremely thin-walled yet exceptionally stiff housing parts for smart phones, notebooks and tablets,” explains Bonefeld.

Bond-Laminates sees itself not only as a pure material supplier, but also as a partner that supports its customers with comprehensive services throughout the entire component development process right up to the start of series production. The company, which is integrated into LANXESS’s High Performance Materials business unit, can draw on the HiAnt competence brand, in which the business unit has bundled all its expertise in materials, composite technologies, simulation methods, component testing, processing and production to support customers. The services include, for example, topology optimization and tips on the correct overmolding of Tepex inserts as part of the component design. Further service elements include the simulation of the forming (drapery) and cooling behavior of composite semi-finished products as well as structural analyses, e. g. for calculating the mechanical load-bearing capacity of Tepex components. The results of these analyses are validated by component tests such as mechanical component or alternating climate tests. Bonefeld: “We also use our fully automated, near-series demonstrator cells to simulate the production processes of our customers in order to determine process parameters and identify possibilities for quality assurance and improvement.”
