This prepreg is especially designed for the manufacturing of high performance carbon/epoxy prepreg moulds cured in oven and under vacuum.

Vacuum curing conditions: 16 hours at 65 °C, 5 hours at 80 ºC and others.

Recommended Cure Cycle:

  • 1st dwell at 75°C for 1h, at a ramp rate of 1°C/min under full vacuum
  • 2nd dwell at 120°C for 1h, at a ramp rate of 2-3°C/min under full vacuum

For optimum performance, it is recommended that the part is subject to a post cure to 150°C for 2 hours.  
 
Resulting panel thickness for OPS75 surface and PSB75 bulking after full consolidation, around 1.5-1.7mm. For additional thickness and stiffness if required, additional PSB75 bulk or OPS75 surface plies may be used.
 
Other cure cycles and additional reinforcements are available on request.
 
Use of perforated release film is recommended.
 
Curing Schedule is meant to be a guide only and is subject to local conditions.

To avoid exotherm particular care must be taken with thick laminates.

Ramp rates must not exceed 3.0°C per minute during initial cure.

Ramp rates must not exceed 0.3°C per minute during post cure (free standing).
