A two-component less viscous epoxy was used for bonding the
laminates to each other. The mixing ratio of the epoxy was two
parts resin ~bisphenal A based! to one part hardener ~polyamide!
by volume. The epoxy had a pot life o f1hatroom temperature
and was fully cured after 7 days at 25°C. This epoxy had a longer
gel time and much lower viscosity and was used in between
CFRP sheets to insure the least entrapped voids.
