Prepreg
Manufacturing and sales for the carbon fiber composite materials (except prepreg for aircraft) are handled by ENEOS Techno Materials Corporation.
Overview
As a prepregger, ENEOS is a partner who can provide support for molding businesses, including resin development according to the customer's needs.
- We have over twenty years of experience in prepreg manufacturing at our factory.
- We can meet requirements for not only pitch-based carbon fiber but PAN-based carbon fiber and other types of engineering plastic fiber.
- Consult with us about difficult-to-handle special textiles as well.
- Utilizing resins we have developed, we can manufacture prepreg materials with a variety of characteristics.
Prepreg resins we have developed (examples)
| Resin Type | Feature | Curing Condition | Glass Transition Temperature |
|---|---|---|---|
| Epoxy | General purpose | 130℃/1hr | 140℃ |
| High toughness | 130℃/1hr | 140℃ | |
| High heat resistance | 180℃/2hr | 210℃ | |
| Low temperature cure Fast cure |
90℃/1hr | 90℃ | |
| 130℃/10min | 120℃ | ||
| Cyanate ester | High heat resistance/toughness Low outgas |
180℃/2hr | 230℃ |
| +232℃/2hr | 260℃ | ||
| Benzoxazine | High compressive strength Flame resistance |
185℃/2hr | 190℃ |

Is composite material performance determined by the fiber alone?
A composite material consists of fiber and matrix resin. Therefore, just because the fiber is good does not mean that the composite will be good.
ENEOS has a variety of prepregs that utilize resins developed by us and provide high toughness, high heat resistance, and low outgas.
