Marine SPRINT® Materials from SP-High Modulus
|
SPRINT® is a unique patented material and processing technology that allows high quality composite components, with high mechanical properties and very low void content, to be produced rapidly and economically.
SPRINT® materials are laid up in a mould and vacuum bagged as for conventional prepreg. However, when the vacuum is applied, the air transport properties of the dry reinforcement enable air trapped in the fibre bundles and between layers to be easily removed.

When the temperature is then raised for the cure, the resin film softens and flows into the air-free reinforcement. The void content of the resultant laminate is extremely low (typically 0-0.5%).
What is SPRINT®
SPRINT® materials consist of a layer of fibre reinforcement either side of a precast, pre-catalysed resin film with a very lightweight tack film on one face. The material therefore has the appearance of dry reinforcement, which has resin concealed at its centre.
SPRINT® materials are produced by a process that differs from conventional prepreg so that the fibres in the reinforcements remain dry and unimpregnated by the resin.
SPRINT® Combinations
SPRINT® is available in a number of resin and reinforcement combinations using woven and stitched carbon, glass, aramid and hybrids in a multitude of styles. These can be in the form of random mat, woven fabrics, stitched fabrics, or simple rovings.
SPRINT® Technology
Unlike conventional prepreg, the fibres are not held rigidly by the resin, so the SPRINT® prepreg is much more drapable. The technology has been successfully applied to a range of applications from large structures (with thick laminates) to small complex mouldings.
As with prepregs, some of the more popular SPRINT® products are continually held in stock as the “SP-High Modulus Essentials” range – the products you want, when you want them.
