Chem-Trend’s new release agent designed for lightweight composite materials.
Chem-Trend is helping the aerospace industry remove mass, lower fuel consumption and respect the environment with a release agent targeted for use with composite materials.
Zyvax TakeOff is a newly developed water-based, semi-permanent release agent specifically formulated for aerospace manufacturers and is especially effective for vacuum bagged and autoclave moulding of epoxy carbon fibre prepreg. This water-based release agent does not require a sealer in most cases when used on high-quality mould surfaces in aerospace and other epoxy prepreg applications.
“Today’s airplane manufacturers are turning to greater use of composite parts to improve cost and quality and reduce maintenance,” said George Barton, Senior Business Development Director for Composites at Chem-Trend. “Zyvax TakeOff is an integral part of the process, allowing composites to release easily, quickly and flawlessly from moulds. It is easily applied by wiping or spraying and reduces waste and scrap.”
Zyvax mould release systems from Chem-Trend are developed specifically to address the moulding needs of premium aerospace composites materials. According to Chem-Trend, a distinct advantage of TakeOff is its ability to be applied to moulds at varying temperatures, thus reducing the required downtime to allow the mould to cool, as is sometimes needed when using solvent-based release agents. TakeOff needs only a minimal number of coats to become effective, with short dry times between applications. It also provides multiple release capability, potentially contributing to improved productivity in the manufacturing process.
Zyvax TakeOff is ideal for aircraft application because it is specifically formulated to work on extremely large epoxy moulded parts and uses an environmentally conscious water-based carrier. Additionally, there is very low transfer of the release agent to the moulded part. That can eliminate or significantly reduce any cleaning process that might be required prior to a post-moulding procedure, such as painting and gluing. This saves material, time and money for manufacturers.
For those parts that do require cleaning, only a mild detergent and water are needed to easily remove any transferred release material. TakeOff is virtually solvent-free, exceeds the most demanding environmental requirements and provides employees a more pleasant plant environment.
“Aerospace manufacturers are not alone in their use of lightweighting solutions to increase fuel economy and decrease emissions,” said Barton. “Manufacturers in the marine, rail and automotive sectors are also increasing their use of composite materials to gain the same economic advantages. With as much as 50 percent of today’s aircraft comprised of composite material, release agents play a major role in production.
“As the evolution of aircraft construction continues, manufacturers will have an even greater demand for products like Zyvax TakeOff that enable the use of lightweight composites. This allows manufacturers to retain the structural integrity of metal with much less mass while decreasing fuel consumption.”
Cobra International is celebrating its 40th year and has commissioned a book that will look at 40 key projects and 40 key people that were integral to the company’s growth. ‘Klaus Simmer and The King Cobra: A breakthrough in surfboard design and production technology’ is an extract article from this book and a breakthrough composites product for Cobra, establishing its presence as a manufacturer of high performance windsurf boards and creating global visibility for the Cobra brand.
The Aachen Center for Integrative Lightweight Production (AZL) and the Institute of Plastics Processing (IKV) at RWTH Aachen University are commencing a study into the use of thermoplastic tapes in injection moulded parts. Companies interested in joining the study are invited to a kick-off event during Fakuma 2018 in Friedrichshafen, Germany, on 18 October.
ZSK will hold its bi-annual technology showcase on 21-22 September 2018 at its Krefeld, Germany, headquarters. The Embroidery Technology Show assembles more than 25 exhibitors from around the world to discuss emerging trends in the embroidery manufacturing industry and demonstrate the latest products produced using techniques such as tailored fibre placement (TFP) or smart textiles.
