Metallized
glass
fibers
have
the
excellent
electric
conductivity
and
low
price
compared
with
carbon
fibers.
Metallized
glass
fibers
were
fabricated
by
coating
copper
on
the
surface
using
different
processing
technologies
and
the
effects
of
processing
technology
on
the
properties
of
copper
coated
glass
fibers
were
discussed.
By
hand
laying
up
molding,
metallized
glass
fiber
reinforced
plastic
(MGFRP)
with
good
dispersion
and
interfacial
cohesion
was
prepared
successfully.
The
piezoresistive
properties
of
MGFRP
were
compared
with
those
of
carbon
fiber
reinforced
plastic
(CFPR).
The
results
show
that
copper
coated
on
glass
fibers
with
volume
resistivity
of
10−5 ·cm
have
the
good
electrical
conductivity
and
cohesion
between
two
phases
through
optimizing
the
pretreatment
technology
of
glass
fibers
and
the
formula
of
chemical
plating
solution.
MGFRP
has
the
distinct
and
similar
piezoresistive
characteristics
with
CFRP
and
exhibits
the
better
piezoresistive
sensitivity
to
fracture.
