Tape / Fiber Placement
Tape placement is an advanced
composites process that orients resin preimpregnated
high-strength reinforcement fibers in specific
directions. Part weight is minimized by
concentrating high strength in only the
directions needed. It is widely used in
the fabrication of high strength/weight
ratio parts in the aerospace industry such
as aircraft wing and body skins,control
surfaces, spacecraft and missiles. Automated
equipment is predominately used for large
structures while hand tape placement remains
widely used but usually for smaller parts.
Most automated machines are large, sophisticated
and represent a major capitol investment.
Resin choices for tapes can be grouped by
processing characteristics. These are, Tacky,
B-staged resins later cured to a thermoset
stage, e.g., epoxies. Non-tacky solid resins
that melt and flow prior to curing to a
thermoset polymer, e.g., bismaleimides and
non-tacky thermoplastic resins processed
entirely by melting and freezing, e.g.,
polyetherketone, (PEEK), and polyphenylene
sulfide, (PPS).
