FEATURES & BENEFITS

Finding a Better Way

 

The Epsilon™ combination of processing ease and outstanding mechanical properties makes it possible to achieve significant cost and weight savings in the manufacture of composite structures. For prepreg structural aerospace applications, the benzoxazine chemistry used in Epsilon™ offers several clear advantages over a high performance epoxy system:

• Low moisture absorption
• High temperature performance
• High hot/wet property retention
• High compression strength and modulus
• Good adhesion to fibers
• Excellent FST performance

 

Shop Floor Stability and Easy Storage/Transportation

 

In the manufacture of aircraft wings, fuselages and flight control surfaces, the stability of these Epsilon™ resins at ambient temperature makes them ideal in the assembly of large parts and in automated tape-laying machines. With Epsilon™ manufacturers don't have to worry about the resin polymerizing, so the time required to complete the assembly is not limited to the relatively short 30- to 45-day work lifes of epoxy resins.

Epsilon™ resins also provide an alternative to the hazards of phenolic prepregs in aircraft interior assembly (such as vapors that emerge during cure). The high temperature strength and performance of Epsilon™ resins make them ideal for hot sections of the aircraft around landing gear doors (soak back from brakes), engine components (nacelles) and areas in the aircraft where indirect heating is present.

Plus, the fire-retardant qualities of the benzoxazine chemistry used in Epsilon™ resins make them suitable for aircraft interiors and for aircraft interior structural applications.
