Continuous
fiber-reinforced
polymers for aerospace
Over 20 years ago, the aerospace industry
was an early adopter of then-new additive
manufacturing (AM) technologies. The
reasoning was to take advantage of the
performance, lead time, and cost
advantages that AM afforded, especially for
low-rate production. The aerospace
industry incorporated AM design into their
flight hardware and, for some applications,
AM has become the baseline technology
today.
The initial applications utilized
unreinforced polymer AM parts, which had
the highest process maturity at the time.
Due to early material performance
suitability for non- and low-load bearing
applications, the use space was limited to
non-critical parts (e.g., safety, flight,

mission, maintenance). The constraints of
performance of polymer AM have helped
burgeon the rise of metallic AM, where
applications need to be structural and
polymer AM does not offer a solution. The
next logical step and an ongoing goal is to
merge AM with structural composite
materials (e.g., continuous fiber resin
matrix) forming the basis of continuous
fiber-reinforced polymer additive
manufacturing (CFRPAM).
As CFRPAM companies continue to
develop their technologies to bring them to
market, there are several challenges and
potentially unsettled issues. One of the very
first questions that comes up among
traditional composite engineers is related
to the final mechanical properties and how
