TO GLASS FIBER
REINFORECED POLYMER

Introduction and design brief
This project aims at transform manufacturing design from
traditional way(which is spot welding) to glass reinforced polymer.
Traditional system(spot welding) is easy and simple to be
used .There is no presences of dangerous fame since it doesn’t
required fillers to create a joint.it can be perform without any
special skills. spot welding provide simple way of combining
different type of metals However, it has be found to be too weak
under impact to be used commercially. The enhancement of the
system to glass fiber reinforce polymer will make it much stronger
than the current system. Glass fiber reinforced polymer as
received much attention in recent years due its high resistance to
corrosion, which it’s more economical and also more
efficient.GFRP is a thermosetting entailed of glass fiber embedded
within a polymer matrix. The GFRP has many possible uses in
fields such as IT, mechatronic, Electrical and mechanical.
This paper present a set of criteria of selecting the composite
components that it is needed in the manufacturing design and
also the steps to be followed during the manufacturing process.
The incorporation of the GFRP to the system has significantly
increased flexibility

Current system
Spot welding is the most common way of combining two sheets of
thin metal, such as stainless still. To join them together, the
layers are placed between the two welding electrodes to which
pressure is applied. A high degree of resistance is generated
when an electric current is transmited through welding electrodes
and the sheet of metal; this result adequate heat generated to
melt the metal and combine it. The material being welded
determined the amount of current, amount of time that the
current is passed through the electrodes and applied pressure.
This method of combining metals together by spot welding can be
quickly and efficiently. However, the resulting joint will not be
adequate for all purposes, and it results in a join which is
generally weak, mostly when the procedure is unfollowed
correctly. The key disadvantages of this system is that:
 Electrode must reach both material side being joint
 Particular spot welding machine can manage to hold a
certain width of metals, its most five to fifty inches, even
though the electrode is adjustable it has a limits
 The shape and size of an electrode enhanced a lot in
determining the size and strength of a metal
 In case there could be any inefficiency of current or force
holding the metals together, the spot-welded may be weak
 In most cases the spot welded point is generally weak
 The appearance of jointed part is mostly ugly and there can
be cracks
 Mostly metals formed through spot welding process has high
degree of being affected by corrosion
The objective of this project

The purposed of this project is to solve the current problems in
the welding spot system and provide material which has better
performance. The key objectives of this project are to provide
equipment with the following features;
 To provide durable materials, that can last for long with
minimal maintains and replacement
 To submit content with high resistance to corrosion and rot,
hence increasing its services life
 To provide content which weightless therefore reducing the
transportation cost and installation cost
 To provide insulating materials which save energy during
usage
 To economize the use of materials, the composite industry is
aiming at recycling of materials as fillers and resins. There is
also a target to replace petroleum-based materials with bio-
based materials
 To reduce environmental impact and this is achieved
through direct application and even through functional
applications. Direct applications are shown in applications
that minimize energy requirement such as;
 Fiberglass window lineal and doors do not rot, rust or swell
and this results to no leakages of air a secure seal compared
to steel products
 The heavy truck industry has moved to predominately
composite
Composite materials used
A thermoset polymer matrix should meet specific standards
in order to make suitable for GFRP and must be ensured that
there is successful reinforcement of the polymer. The matrix
should be saturated and suitably bonded both physically and
chemically with the fiber reinforcement for a maximum
strength within an appropriate curing time. Fiber is wholly
protected from flaws that will reduce effectiveness and
strength .the fiber must be kept apart from each other .when
failure occur it will be localized. If these failures occur the
