BYK will premiere BYK-C 8013, a solvent-free, polymeric coupling agent for improving the mechanical strength of carbon fibre reinforced, radical-curing systems.
Claimed to be the world’s first coupling agent for carbon fibre, it is used in vinyl esters and unsaturated polyester resins that are processed to composite parts using carbon fibre. The cross-fibre strength is greatly improved, making far greater design freedom possible. BYK-C 8013 increases both the transverse tensile strength and the flexible strength of the composite by means of improved fibre-matrix bonding. The chemical structure of the additive provides simultaneous adhesion to the fibre and to the resin matrix. This property makes changes in the component design possible, and it enables particularly durable components to be manufactured. In hot-curing processes such as SMC/BMC, pultrusion, prepreg or RTM, BYK-C 8013 brings about increases in strength of up to 70%.
The reactive additive can be introduced to the size during fibre production or to the resin shortly before processing. In subsequent, so-called 'second sizing,' BYKC 8013 can, for example, be applied to the fibre in a spraying process, without the need to remove the first coat beforehand.

The Institute for Advanced Composites Manufacturing Innovation (IACMI) has announced the Phase I completion of a project led by DuPont, partnering with Fibrtec and Purdue University, focused on the creation of a new carbon fibre composite manufacturing process that exhibits improved fabric formability characteristics compared to traditional woven materials.
CGTech will showcase its expanded range of software applications for the aerospace industry at the Farnborough International Airshow on 16-20 July 2018.
Powertrains, be they conventional, hybrid or fully electric, will need to be light in weight if carmakers are to meet the stringent regulations on carbon dioxide emissions (CO2) to come into force in 2025 – and composites will be key to making this happen. This was the message highlighted at the Lightweight Composite Solutions Conference organised by Vyncolit and Sumitomo Bakelite Co Ltd and held in Gent, Belgium.
