To meet stringent flame retardancy demands of areas such as transportation and electronics, components based on thermosets increasingly require a soluble, non-powder flame retardant (FR) due to low layer thicknesses in the final product or due to liquid processing methods. Two flame-retardants developed by Clariant meet these requirements.

Avoiding Filter Effects of  Flame Retardants

Short glass fiber-reinforced plastics are exposed to complex load cases during the operating time. Therefore, the influence of alternating load and frequency in the form of load spectra on material fatigue is investigated and an integrative computational method for structural design is presented. With this practical approach, a fast fatigue life estimation is possible.

Climate change and the transport revolution are demanding smart fiber-reinforced composite solutions. In sectors such as the marine industry, infrastructure, and rail vehicle construction, many different fire protection concepts are competing. The composites industry is paying increased attention to recycling.

Composites Are Trendsetters in Lightweight Design

Bio-based plastics can lock away vast quantities of CO<sub>2</sub> in durable, recyclable applications and make a real contribution to climate protection. All that is needed for this is the right product design and a functioning circular economy. By focusing more on this approach, the plastics sector has the chance to evolve into a key industry of a green economy.

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.

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.

Reduced Settling Behavior in Multi Material Components

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.

Anyone seeking to replace a metal component by a plastic one, to reduce the number of component parts from eight to three and simultaneously cut both the weight and manufacturing costs needs to take great care to ensure that all specifications are met – especially if the component is used in a hot gearbox and is subject to high mechanical stress.

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.

When Fibers Mix with Platelets

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.
