CYCOM 2237 is Cytec Engineered Materials’
version of PMR-15. It is formulated for high temperature
applications where low void contents are critical. CYCOM
2237 has the best overall balance of processing behavior,
thermo-oxidative stability and retention of properties
in the 500°F (260°C) to 550°F (288°C)
range. CYCOM 2237’s thermo-oxidative stability
and micro-crack resistance makes it ideal for jet engine
and other fatigue load components like bypass ducts,
gear box covers, transmission housings, vent tubes,
fan stator & vane assemblies, nozzle flaps, core
cowls, particle separator swirl frames and compression
molded bearings.
CYCOM 2237 prepreg can be autoclave
cured, vacuum bag processed or compression molded.
CYCOM 2237 is solution impregnated
on a variety of fibers and fabrics. It is currently
available on glass, quartz & graphite reinforcements.
Product forms are unidirectional tape, non-woven mat,
and woven fabrics. Generally available widths are 12
inches for UD tape, 24 inches for mat & 60 inches
for woven fabrics.
