SPECIAL RECOMMENDATIONS
Special RecommendationsRecommended cure is one step at 140°C, pressure application (0.7 MPa), then 1 hour at 170°C. Post cure: 3 hours at 180°C. · The same resin can accommodate High Strength (HT-S) or type AS carbon fibres. · When continuous use temperature does not exceed 120°C, another prepreg with similar properties, Carboform 87, can be used.
