PREPREGS
Prepregs
are a combination between a thermoset or thermoplastic matrix
and a high performance reinforcement, ready to use for manufacturing.
Those products must be kept at a very low temperature (-18°C) :
they have to be stored in a cold chamber, and to be implemented
with a oven.
| Characteristics
|
good
surface aspect, homogeneous resin implementation all over
the fabric surface. |
| Matrix |
-
epoxy, phenolic, polyester, bismaleimide
- low temperature system (75°C), 120 or 180°C system (epoxy) |
| Reinforcement
|
-
glass or carbon unidirectionnal webs
- glass, carbon, aramid or hybrid fabric
- multiaxial glass or carbon fabric
- balanced or unidirectionnal |
