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. 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.

SE 70 - Low Temperature Cure High Toughness Epoxy

 

Prepreg System

 
   

      

  •    Low temperature 70°C curing

  •    Faster cycle times at elevated temperature

  •    Excellent balance of mechanical properties and toughness

  •    Long outlife - up to 4 weeks @ 18-22°C

  •    Range of compatible adhesive films and ancillary products

  •    Excellent surface finish

  •    Good Tg

  •    Suitable for vacuum bag, press or autoclave consolidation

 

SP’s SE 70 is a hot melt, low temperature cure, epoxy prepreg system. It has been developed for use in the construction of large components using low energy cure cycles. Excellent properties can be achieved with a processing temperature of just 70°C. At this cure temperature the system exhibits very good mechanical properties and excellent toughness.

 

Cure temperature for a 16 hours cure cycle is 70°C - this temperature allows less expensive tooling and ovens to be used, with lower thermal movement and distortion. Faster cures are available from higher cure temperatures. However, thicker sections (>10mm) will require the insertion of a suitable dwell into the cure cycle. Up to 20mm thick laminates may be moulded at 70°C with a peak exotherm only slightly above the cure temperature.

SE 84LV - Low Temperature Cure Epoxy Prepreg System 

 
   
  •    Versatile, high-strength prepreg system

  •    Curable at temperatures as low as 80°C

  •    Can be processed with vacuum-only processing

  •    Excellent tack

  •    Low viscosity - Ideal for use with heavy fibre weights

                                                  

SE 84LV is an exceptionally versatile hot-melt, epoxy prepreg. It can be cured at temperatures as low as 80°C, or it can be used for faster moulding of components at 120°C. This is achieved with an extremely good outlife of up to 8 weeks at 18-22°C. It is a toughened system, and offers excellent mechanical properties on a wide variety of reinforcing fabrics and fibres.

 

SE 84LV is commonly used in vacuum bagging, press-moulding, autoclave and other pressure moulding processes.

 

SE 84LV is a low viscosity system used with heavy fibre weights where low-flow processing conditions (vacuum bag pressure and minimum cure temperature), are likely to be used. With its high compressive strength it is widely used in large heavily loaded components, such as yacht hulls, and spars. It has been selected for use by various America’s Cup syndicates and boats racing in the Volvo Ocean Race.

SE 85GT - Epoxy Prepreg System

 
   
  •    Highly impact resistant

  •    Rubber toughened system - excellent resistance to micro-cracking

  •    Controlled flow

  •    Good surface finishes possible

  •    Self adhesive - high peel strengths

                                                 
The SE 85GT series are highly toughened hot-melt, epoxy prepregs that offer an extremely good balance of mechanical properties. They are ideal for structural components where improved impact performance and resistance to resin microcracking is desired. SE 85GT can be cured at 80°C, yet retains an outlife of up to 56 days at 23°C. With its 3/4 hour cure at 120°C, it is also suitable for the quick manufacture of parts, and is also used in the development of trial components.

 

SE 85GT has medium flow characteristics, so that heavy reinforcements can be easily wet out, and good consolidation can be achieved in very thick (>25mm) laminates, under just vacuum bag pressures. Its flow behaviour also means that it can produce excellent surface finishes when used in pressure-moulded components.

 

SE 85GTBL is a black pigmented variant, often used in carbon fabrics to provide an excellent deep black gloss finish on the outer surface of carbon components such as yacht spars and race car parts.

  • Rubber toughened system

  • Good balance of mechanical properties

  • Good resistance to micro-cracking

  • Rated to FAR25.853 and FMVSS302

                                                   

SE 85FR is a fire-retardant, toughened hot-melt, epoxy prepreg system that offers an extremely good balance of mechanical properties. It has been tested to MVSS302 and FAR25.853 (60 secs and 12 secs vertical burn) fire safety standards.
