Epoxy Prepregs

EH250 / EP 112

ESTABLISHED AEROSPACE EPOXY PREPREG
  • Highly toughened epoxy resin systems
  • Controlled resin flow
  • Self-extinguishing
  • Outstanding adhesion to core materials
  • High volume, reference aerospace epoxy system

Introduction

EH 250 / EP 112 resin is a self-adhesive epoxy system designed for a wide variety of manufacturing processes, controlled flow during curing, high interlaminar shear strength and outstanding adhesion to cores and metabolic substrates.

This prepreg material is suitable for the manufacture of high performance composite structures and light-weight sandwich components with high specific mechanical properties. EH 250 / EP 112 also benefits from excellent impact properties and very strong adhesion to honeycomb cores as demanded by aircraft secondary structures such as radomes, fairing and leading edges.

The resin matrix EH 250 / EP 112 is a 125ºC (257ºF) system, which can be cured at a temperature range between 120ºC (248ºF) and 160ºC (320ºF) and is offered in different tack levels to meet fabrication requirements of curved and complex shaped components.

Both monolithic and sandwich structures can be easily manufactured with this prepreg by press, vacuum bag and autoclave moulding with a pressure of at least 0.7 bar (10 psi).
