Evonik at CCE 2016: Showcases Silica Nanoparticles & Crosslinkers for Composites

Published on 2016-09-01. Author : SpecialChem

Evonik is showcasing NANOPOX® silica nanoparticles and its innovative products and solutions developed in close collaboration with customers at China Composites Expo 2016 from August 31 to September 2.

A growing number of challenges presented by renewable energy, efficient resource management and ecological aspects can only be mastered now and in the future by using lightweight construction. Fiber-reinforced composites will play a major role in this regard as one of the key technologies for the 21st century.

NANOPOX®: Using NANOPOX® the performance of fiber-reinforced composites parts can be improved significantly: modulus, strength and compressive strength as well as toughness are increased. The fatigue performance is improved significantly. And due to the small particle size of 20 nm viscosity is not increased. Furthermore even close meshed fabrics are penetrated by the particles. This makes NANOPOX® suitable for all manufacturing processes like prepregging, filament winding, infusion or RTM.

Enhanced Properties Using NANOPOX® Nanosilica

  • Significantly improved modulus and flexural strength
  • Drastically improved fatigue performance
  • Increased toughness
  • Improved surface quality (reduced print through)
  • Reduced microcrack formation

VESTAMIN®: Aliphatic diamines from the VESTAMIN® range are industry-standard crosslinkers for high-performance epoxy systems. Typical applications include industrial floorings, marine and anticorrosive paints. Also, high-performance composites are a major field of application. All major processing fields like Resin-Transfer-Molding (RTM), wet-pressing and also pultrusion are covered.

VESTAMIN® Crosslinkers for Transparent High Performance Plastics

Strength of a GFRC improved by nanosilica addition
  • Crystal-clear, Optical transparency
  • High mechanical stability
  • High thermostability
  • High viscosity
  • Good chemical resistance compared to other plastics
  • Good electrical properties
  • Low molding shrinkage

Committed to Sustainability and Research

The dedication of Evonik toward fiber reinforced composites is proven by the establishment of the Composites Project House, a highly specialized research center.

Inside this think tank, scientists are working close to the market on the products and processes for tomorrow's world where manufacturing fiber-reinforced composites will play a significant role. Interdisciplinary cooperation between chemists, engineers and technicians from different sectors and industries fosters a creative climate where highly efficient, energy-saving manufacturing processes are being developed to support the use of renewable raw materials in industry.

Recycling carbon fibers from components or semi-finished products is another process that Evonik researchers are working on as an important issue affecting the future. Their valuable work is prioritizing ecological as well as economic factors and addressing the needs of our global community today and tomorrow.
