14. DELIVERING A COMPREHENSIVE RANGE OF
REINFORCEMENT SOLUTIONS FOR PULTRUSION
Single-End Rovings
Unifilo®/ Continuous
Filament Mats
Non-wovens
Complexes, Fabrics,
Stitched and Needled
Mats
Bulky Rovings
Single-End rovings are generally
used in all pultruded products,
usually as principal reinforcement
Provide axial strength and
stiffness
High reinforcement content
Available in a range of tex values
Specifically sized to different resin
systems for optimal performance
Unifilo® mats are also widely used
in pultrusion process for better
transverse mechanical properties
High mat tensile strength, also at
elevated temperatures when wet
with resin
Low density
Easy processing: both faces well
bound and easy to splice
Good compatibility with UP, VE,
Epoxy and acrylic resins
Available in a full range of weights
and widths
Veils are designed to create a high
quality surface layer on the
pultruded part
Small bundle size to give uniform
and veil-like appearance
Easy wet out in most pultrusion
resins
Fabrics, complexes and mats –
with sufficient tensile strength for
processing through a die, and
which can be impregnated with
resin under operating conditions –
may all be used
Being filamentized to a greater or
lesser extent, producing loops or
filaments misaligned from the
axial direction
Provides some reinforcement in
the transverse direction to
improve shear properties
Produces a scouring action to
clean the die and prevent lost
edges in tight radii
Easy to wet out
