Processability of novel
co-blended resin systems in
the vacuum infusion process
Southampton University is investigating the processability of novel co-blended resin systems in the vacuum
infusion process to manufacture fire-retardant marine
composites as part of a joint project with Bolton University under an EPSRC grant.

ue to their specific strength and
stiffness properties, fibre-reinforced polymer (FRP) composites are heavily used in load-bearing
structures in a variety of applications
in marine, automotive, and other
ground transport industries. One
of the most serious problems with
FRP composites is their combustibility, which results in heavy soot and
smoke.
Unsaturated polyester (UP) resin,
crosslinked with styrene, is probably
the most widely used thermoset resin
system for GFRP composite manufacturing due to its low cost, excellent
processability, reasonable moisture
and chemical resistance, and generally
good mechanical properties. However,
UP resin is combustible and burns
easily in fire conditions [1]. In the
current project, the global aim is to
improve the fire performance of glassfibre-reinforced UP matrix composites by reducing the combustibility
of UP resin through co-blending with
phenolic resins. This is a joint project
[1] with the Fire Materials Group at
the University of Bolton and the Fluid
Structure Interactions (FSI) Group
at the University of Southampton.
As part of the project, the focus is to
optimise the physical and chemical
properties of the blends to enable: i)
the resin to be suitable for the vacuum
infusion (VI) process, ii) low temperature cure capability to maximise
compatibility and bonding with glass
fibres, and iii) up-scaling to produce
large laminates and structures in the
VI process. The composite laminates
and structures thus produced are
expected to move towards the fire
performance requirements contained
in the International Convention for
the Safety of Life at Sea (SOLAS) as
