FRP Material Introduction
FRP Material Introduction
FRP (Fiberglass Reinforced Plastic) is produced from a combination of fiberglass reinforcements and thermosetting resins. Since its introduction, this special millennium product has gained wide acceptance for its superior benefits and is presently used all over the world.

Flatness & Thickness Consistency
|
Pultusion is pultruded from heated die, therefore flatness is consistence even cut into smaller sizes.
Thickness is even and consistent.
|
Production of FRP hand-lay
products is based on the
workmanship and has a high
probability of uneven surfaces due to the production process.

Impact Resistance
|
Continuous strand glass mat in FRP
Products distributes the impact load
to prevent surface damage even
under sub-zero temperature and will
not permanently deform and stay flat
for the life of the product under
closed mold pultrusion processing.
High in mechanical strength.
|
Chopped strand mat used in FRP hand-lay products will probably deform or crack under impact
without going under the closed
mold processing and pultrusion system. Low in mechanical
strength.
|
Will permanently deform under impact and take a permanent
set (dishing in trench application due to overloading).High in mechanical strength.

What is Pultrusion Process
Pultrusion is a continuous moulding process fabricating products of uniformsection such as I Beams, Channels, flat Bars, Rods,Hollow Sections, etc. Msing glass fibre, resin, fillet peroxide and a release agent. The glass reinforcement is drawn into a resin impregnation zone where the Mass substrate is thoroughly impregnated with the main mixture. The wet fibrous materiss will be pulled through a preformer into a heated die. The shape of the end product is determined by the configuration of the die and the resin is then polymerised. This continuous and uniform method ensures consistency throughout the entire product length, therefore eliminating the possibility of weak spots.
