Unipreg® General Information
GENERAL CHARACTERISTICS:
Unipreg® is a unidirectional carbon fiber prepreg which can be used in all applications where excellent mechanical and physical properties are required. The main advantages of Unipreg® are:
- Resin system (epoxy) was selected to fully impregnate the unidirectional carbon filaments through its thickness and achieve the best adhesion between the fiber and the matrix in composite.
- All filaments are tensioned and absolutely parallel so the prepreg can fully utilize the properties of every single fiber, thereby the composite has excellent physical-mechanical properties.
- Excellent suitability for structural components.
- The thickness of the prepreg along the width is constant.
- All the physical parameters have very strict tolerance so the weight, resin/fiber content, thickness, width are very precise.
- Silicon paper is used to separate layers which are not coated but impregnated by silicone.
- There is no need of additional fabric or net to constrain the filament.
- Packed by one 14-15 kg reel in the box.
