Scientists from Saxony-Anhalt Create Super Polymer Fibers

Optics play an increasingly important role in plastic components. Glossy and even surfaces are decisive for an attractive appearance. With glass fiber-reinforced polyamides (PA), these requirements can usually only be achieved with an additional coating. A PA specially developed for surface design offers an alternative approach.

For visible components, an even, glossy surface is often desired, which is often difficult to achieve with glass fiber-reinforced PA. PA Grivory G7V from EMS now solves this problem

Thermoplastic tapes are expected to shape the next generation of thermoplastic composites. This calls for highly accurate tape stacking. Engel contributes this technology to achieve a breakthrough by combining high-precision control software with camera technology in tape stacking.

For high production efficiency, a tape stacking unit is best equipped with two robots and one camera station

An Eye for the Essential

Carbon fiber-reinforced plastics (CFRP) are being used in more and more components. Their production is also becoming more and more effective. In the event of damage, however, business continues to be carried out manually. For this reason, greater automation is desirable when repairing CFRP. Automated laser processes could be one way of doing this.

Threaded inserts ensure a secure connection of hybrid components. Under continuous load, effects can occur with thermoplastics due to pressure and temperature, which means that a durable screw connection is no longer guaranteed. Such effects can be prevented by thread inserts with a special surface structure.

A number of examination methods can be used to identify weaknesses caused by incorrect fiber orientation. In particular, the fiber volume content and fiber distribution permit conclusions to be drawn regarding the stiffness and tensile strength behavior. A new ultrasound method offers the flexibility to capture these parameters on the finished component.

Many people have good ideas and intentions. Few have the courage and determination to put them into practice. The young rezemo entrepreneurs Julian Reitze and Stefan Zender are one successful example. In 2019, some three years after their start-up was founded, the company was already producing well over one million compostable coffee capsules per year.

Thermoplastic injection molded parts can be reinforced with local continuous fibers in combination with metallic load application elements. This also makes them suitable for structural applications such as transverse control arms and transmission mountings. A 3D winding technology was tested for potential use in a large-scale production process.

A Chinese supplier provides a number of international auto makers with high-quality long fiber-reinforced thermoplastics in pellet form. A key factor in this success has been the use of novel compounds and the development of custom material solutions. The company therefore invests heavily in research. When it came to producing the pellets on an industrial scale, it opted for German-made pultrusion technology.

Designed to local spatial constraints: the LFT pultrusion line installed at HCJH is about 30 m long and produces up to 1 t of LFT pellets per hour for delivery to customers in the automotive and other industries

In addition to excellent mechanical characteristics and suitability for recycling, the key feature of hybrid lightweight structures made of fiber-reinforced thermoplastics is that automated, large series production is possible. New mold and process technologies were successfully developed within the scope of the ReLei research project, enabling the production of complex shaped sandwich elements in an efficient combined process.

In the ReLei project, several research and industry partners developed a rear shelf based on a fiber-reinforced polyamide as an example for manufacturing a complex sandwich structure

Carbon fibers are due to their high price interesting for recycling. The results of the project RecyCarb enable the multiple use of carbon fibers as functional re-use. First demonstrator parts in the areas of medical technology and automotive prove the industrial feasibility.

Additives often consist of additive mixtures of heterogeneous components. Their anisometry leads to part properties that depend very strongly on the orientation of the additives. For this reason, it is essential to describe such orientation behavior at an early phase of development when additized plastics parts are being designed.

3D printing is a fast-growing market, opening up completely new product and manufacturing options for customers and industry. The newly developed SEAM process significantly extends the options for the efficient manufacture of printed components. An impression of this is conveyed by the example of a fiber-reinforced clamping fixture.

Composites for Future Lightweight Construction

In Hanover, Lamilux will be presenting, among other things, what the company says is the world‘s most UV-resistant GRP top layer. The manufacturer can be found in Hall 27 at Stand D39.

Whether commercial vehicle, last mile or bus industry: the automotive industry requires innovative materials that equip vehicles for everyday challenges and make them more stable, lighter and more sustainable in the future. LAMILUX Composites will be presenting its product innovations made of fiber-reinforced plastic at the IAA in Hanover.

For the seventh time, the GRP specialist LAMILUX Composites is giving the general public a deep insight into the world of glass fiber-reinforced plastics at the IAA. Decades of experience in the commercial vehicle and bus industry as well as quality made in Germany characterize the 100-year-old family-owned company.

In Hanover, Lamilux (Hall 27, booth D 39) will be presenting, among other things, what the company says is the world‘s most UV-resistant GRP top layer. Lamilux Sunsation is the long-awaited revolution in the field of fiber composite plastics, completely redefining the standard for exterior applications, broadening the horizon with regard to image, appearance, care and value, and making investments look like new even after decades in the sun.

Tried and Tested in All Real Applications

Three demonstration models will be exhibited at the LAMILUX stand: The applications of the GRP products will be demonstrated using truck, bus and last-mile vehicle models.

For trucks and last-mile vehicles, this is the impact-resistant, robust material High Impact with AntiBac surface, the non-slip floor covering AntiSlip for interiors and Lamilux Woven Roving S or Lamilux Woven Roving Impact, which protect the underbody from stone chippings. When installed in the roof, the world’s first Lamilux Sunsation reveals the advantages of the innovative gelcoat technology with 20 times better UV resistance than the gelcoats currently available on the market. LAMILUX Composites also enables translucent roofs for daylight intake during loading and unloading.

In the case of buses, Lamilux demonstrates its flair for design: LAMIfoamtex with its soft-touch surface, Composite Floor, which resembles laminate flooring, and LAMIGraph, for interior cladding, are the proven materials of choice here. The manufacturer also presents a robust and durable material, Lamilux Woven Roving X-treme, for use on roofs and side walls. Lamilux AntiSlip non-slip flooring, which is also available as a visually attractive Lamilux Anti Slip Style variant, once again scores points in the luggage compartment.

Focus on Sustainability, Robustness and Hygiene

Installed in a wide range of vehicle types, Lamilux Composites saves a considerable amount of weight while still producing extremely robust superstructures. In sandwich or prefabricated constructions, this composite material sustainably reduces the fuel consumption of the vehicles. High strength and stability create robust constructions that ensure that heavy mechanical stress in daily traffic leaves less traces on the composite materials.

The high damage tolerance also leads to a longer value retention of the vehicle, lower repair costs and easier repair and maintenance. Special materials with additional benefits, such as the non-slip Lamilux  AntiSlip or Lamilux  AntiBac with antibacterial nanosilver surface, round off the product portfolio
