CB or SB Mat:
CB/SB Mat Mainly used in the surface layer of FRP Products:
Characteristics:
Uniform
fiber dispersion, smooth surface, soft hanf-feeling, low binder
content, fast resin impregnation and mould obedience. They fall into
two categories: wrap type CB and hand lay-up type SB. CB Mat is
suitable for wrapping FRP Pipes and vessels because it is capable of
significantly improving the performances of surface layer to realize
longer lifetime and resistance against corrosion, leakage and
compression. SB Mat is suitable for moulds with sophisticated contours
while it is characterized by its good mould obedience and fast resin
penetration, being capable of covering up the texture of underlayer to
create high gloss surface. CB and SB are also applicable to other FRP
Moulding processes such as press moulding centrifugal rotating
moulding, centrifugal rotating moulding etc.
