Prepregs are a
combination of continuous reinforcing fibers that are "preimpregnated"
with thermoset or thermoplastic organic resin matrices. Thermoset resins are more
commonly used and by far, epoxy is used far more than all other matrices.
Prepreg forms
include:
Fabrics,
which are also referred to as "Broadgoods". Fabrics are often chosen
for
ease of handling and are available in many forms, including woven,
non-woven
, single layer and multi-layer.
and
Unidirectional fiber ribbons, which are generally referred to as
"Unidirectional Tape".
Unidirectional tapes are often chosen because they
offer maximum translation of fiber
mechanical properties, such as tensile
and compression strength. Unidirectional
tapes can be made in a variety of
weights and thicknesses.
Using prepregs
rather than in-line "wet" resin impregnation of fibers can offer significant
advantages. Prepregs can have very precisely controlled fiber/resin ratios,
highly controlled tack
and drape (in the case of thermoset resins),
controlled resin flow during the cure process, and
better control of fiber
placement and angle.
Prepregs can be used in processes that range from hand lay-up to highly
automated placement
processes such as tape laying and filament winding.
FiberCote designs and manufactures a variety of prepreg forms with a
versatile range of thermoset
resin matrices and fibers to choose from. Just
as important, we offer assistance with product
selection and design and
application assistance to help ensure that our customers are successful.
