Mexican company Rassini selects Hexcel’s HexPly M901 prepreg system
July 27, 2021 - United States Of America
Rassini, a Mexican leader in composite vehicle suspension systems, has selected advanced composites leader, Hexcel’s, HexPly M901 prepreg system, to speed up product development cycles. It provides an easy-to-process material solution that reduces overall time to market and enables effective early-stage design screening and cost-effective production.
As a specialist in the mass production of composite helper leaf springs for various leading OEMs, Rassini continuously develops innovative new suspension component designs. Due to cost and timing, however, these new products cannot easily be prototyped using conventional high-pressure resin transfer moulding (HP-RTM) technology.
With more than 15 years of experience in delivering glass fibre prepregs for the serial production of composite leaf springs, Hexcel developed its high-performance HexPly M901 prepreg system specifically for this type of application. HexPly M901 combines the right level of structural performance required with simple processing, providing Rassini with a reliable material solution optimised for rapid development and fine-tuning iterations, Hexcel said in a press release.
HexPly M901 is a high Tg epoxy resin prepreg system specifically developed for structural components that will be exposed to harsh thermal and environmental conditions. With short cure cycles of ten minutes and below producing excellent green, or handling, strength of the composite part for demoulding and unidirectional glass fibre aerial weights up to 1,600 grams, HexPly M901 delivers a powerful combination of benefits for suspension component applications.
In addition to having an important role in the new product development cycle, HexPly M901 also offers significant advantages for lower volume serial production of composite mono leaf springs. Combining mechanical performance that is approximately 15 per cent higher than standard prepregs with enhanced fatigue properties and a Tg of up to 200°C following post-cure, HexPly M901 sets a benchmark for performance, according to Hexcel.
“We are very proud of our highly innovative developments with partners such as Rassini that allow us to continuously improve our product range, address our customers’ needs and optimise our composite material solutions for each application,” Claude Despierres, VP sales and marketing-industrial at Hexcel said.
