As a specialist in the mass production of composite helper leaf springs, 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 molding (HP-RTM) technology.

Now the company has chosen the HexPly M901 prepreg system from Hexcel Corp., Stamford, CT/USA to speed up prototype and new product development cycles, reducing overall time to market with an easy to process material solution that enables effective early-stage design screening and cost-effective production.

Hexcel developed this high-performance system with a high glass transition temperature (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 10 mins and below producing excellent green, or handling, strength of the composite part for demolding and unidirectional glass fiber aerial weights up to 1,600 g/m², 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, it offers Rassini SA, Mexico City/Mexico, significant advantages for lower volume serial production of composite mono leaf springs. Combining mechanical performance that is approx. 15% higher than standard prepregs with enhanced fatigue properties and a Tg of up to 200˚C following post-cure.
