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.

and 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.
Nelcote™ 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. |
