Trends in Composite Manufacturing

Colored plastics are not just a marketing gimmick, but fulfill important functions with technical components. In particular, they warn of hazards and permit the fast and direct identification of components. However, when coloring such plastic components, the processors are faced with several difficulties. For example, the colorants used must exhibit long-term resistance to high temperatures and must not impair the polymer’s mechanical properties. Therefore, when selecting the colorant, compounders and processors must observe several important points.

Avoiding Undesirable Finger Prints 

PEEK was invented a little over 40 years ago, and so is a relatively young high-performing thermoplastic polymer. Nevertheless, continuous development of products and processing technologies enables a range of advanced applications in the automotive, aerospace, electronics, energy, and food-and-beverage sectors, as well as the medical industry.

The High-Performance Polymer Opens up New Possibilities for Processing Methods  and Applications

The traditional markets for glass fiber-reinforced thermoplastics remain stable. Thermoplastic composites are gaining fast with 3D-printing and hybrid processing techniques. The fiber composite industry is tackling the recycling issue with pragmatic ideas.

Thanks to a patented plastic alloy based on nanotechnology, PPS compounds can be created that are tracking-resistant, even at very high voltages. These compounds prevent the undesired process of carbonization that can lead to an electrical short on the material surface. The PPS is especially suited for high-voltage applications in electric vehicles.

Immune to Electrical Breakdown

Solid lubricants such as PTFE offer advantages over oils, greases or silicones in conveying systems. Research on low friction and wear was conducted on a lubricant system with POM core and PTFE surface layer. The second part of this article describes the influencing factors, material properties, and processing of such a compound material.
