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%). Structural SPRINT is divided into two systems – ST70 and ST95, both of which are available in glass or carbon versions, in a range of reinforcements.

Gurit has a range of surfacing materials specific to a number of applications, for use with the prepreg and SPRINT range.  They are easy to lay up and provide a pinhole free finish with...
