The patent-approved ST 95 Structural SPRINT™ is a moulding material that consists of two layers of carbon or glass reinforcement either side of a precast, precatalysed resin film. The material therefore has the appearance of dry reinforcement that has resin concealed at its centre. ST 95 is available in woven or unidirectional fabric skewed to ± 45° angles in a range of weights and fabric formats with a light tack film on one side to aid mould placement.
ST 95 is a toughened hot-melt, epoxy resin that offers an extremely good balance of mechanical properties. It has been specially formulated to maximise the outlife of SPRINT™ products at room temperature. It is ideal for structural components where improved impact performance and resistance to resin microcracking is desired.
ST 95 has a flexible cure envelope from 12 hours at 85°C to 1 hour at 120°C. This makes it suitable for use in regular part production as well as for the development of trial components. The material is highly drapeable and has been designed for simple vacuum bag processing.
ST 95 can be used in the making of chassis, bulkheads and general structural items for automotive, marine and industrial applications.
