Marine Prepreg Materials from SP-High Modulus

Pre-impregnated materials (prepregs) are reinforcement fibres or fabrics into which a pre-catalysed resin system has been impregnated by a machine. The resin systems in these materials react only very slowly at room temperature, giving rise to working times of many days to several months. The prepreg resins can only be fully cured by heating them to the prescribed cure temperature.			> Prepreg Materials - Low Temperature Cure (70°C - 80°C) - High Temperature Cure (80°C - 120°C) > Mono-component Pastes > Adhesive Films
The accuracy of the machinery used to combine the fabric or fibre with the resin system ensures that laminates produced from prepregs have more consistent and higher fibre contents than can be achieved by wet lay-up techniques. Furthermore, this technology allows the use of very tough and strong resin systems that would be too high in viscosity to be impregnated by hand.

Solvent-free Technology

Conventional impregnation techniques dilute the resin system in a solvent, which is evaporated after impregnation in a drying tower. SP-High Modulus prepregs all use the latest solvent-free, hot-melt technology.

This combines the prepreg resin system with the reinforcement using heat to reduce resin viscosity and pressure to assist resin impregnation. Besides producing a volatile-free product, the solvent-free nature of this process is far more environmentally acceptable than the more traditional ‘solvent tower’ process.

Quality Control

Every prepreg product produced by SP-High Modulus is monitored on-line with sophisticated measuring equipment based around techniques such as beta-ray gauging. This gives the products their highly accurate and consistent resin contents.
