3 First of all… GFRP or GRP Glass Fibre Introduction Makeup Pros and Cons Properties Uses History Future

4 An introduction to Fibreglass Strength Weight 25% more than Mild Steel.. Same as Cast Iron 20% less than Mild Steel... 10% heavier than cotton.. 40% lighter than Aluminium… CostSame as Aluminium Introduction Makeup Pros and Cons Properties Uses History Future

5 What is Fibreglass? Fibreglass is a composite It is made of very thin glass fibres embedded in a resin A combination of two materials giving enhanced properties A combination of two materials giving enhanced properties Introduction Makeup Pros and Cons Properties Uses History Future

6 Why use Fibreglass?

7 The Makeup of Fibreglass

8 The Recipe for Fibreglass Glass fibres Resin ‘Suitable liquid’ + = Introduction Makeup Pros and Cons Properties Uses History Future

9 Used in bullet-proof jackets Introduction Makeup Pros and Cons Properties Uses History Future So why is fibreglass strong and durable?

10 What affects its strength and durability? The number of glass fibres The type of resin Weathering? There is a balance!Note: The direction of the glass fibres Introduction Makeup Pros and Cons Properties Uses History Future

11 Going Deeper into Fibreglass Fibreglas s Glass Fibres Resi n Glass Fibres Introduction Makeup Pros and Cons Properties Uses History Future

12 How thin are the glass fibres? More than 150 kilometres from one marble 16mm in diameter! 1/20th the width of human hair! Introduction Makeup Pros and Cons Properties Uses History Future

13 Going Deeper into Fibreglass Fibreglas s Glass Fibres Resi n Glass Fibres Introduction Makeup Pros and Cons Properties Uses History Future

14 What about the resin? Firstly there are different types of resin The three most common ones are Polyester Vinyl ester Epoxy Introduction Makeup Pros and Cons Properties Uses History Future

15 How the resin is made Polyester Vinyl ester Epoxy ‘Suitable liquid’ Catalyst Additives —Colour —Other chemicals to enhance properties Introduction Makeup Pros and Cons Properties Uses History Future

16 How the resin is made + Catalyst Polyester Vinyl ester Epoxy Introduction Makeup Pros and Cons Properties Uses History Future

17 …and Epoxy? How the resin is made Polyester Vinyl ester Epoxy + Hardener Takes part in the reaction Usually an amine Introduction Makeup Pros and Cons Properties Uses History Future

18 The Pros and Cons of using Epoxy Shrinks less during curing Curing ratios have to be very accurate Greater Chemical resistance Pro s Con s Introduction Makeup Pros and Cons Properties Uses History Future

19 The Pros and Cons of using Epoxy Introduction Makeup Pros and Cons Properties Uses History Future Also to note...

20 The Pros and Cons of using Epoxy Shrinks less during curing Curing ratios have to be very accurate Greater Chemical resistance Costs a lot more Stronger composite Pro s Con s Corrosive to handle Introduction Makeup Pros and Cons Properties Uses History Future

21 So where does Vinyl Ester come in? Vinyl ester is essentially polyester resin with epoxy molecules in the main molecular structure Introduction Makeup Pros and Cons Properties Uses History Future

22 How the resin is made Polyester Vinyl ester Epoxy + Catalyst Introduction Makeup Pros and Cons Properties Uses History Future

23 …and as a result... Vinyl ester is less susceptible to damage by water It is stronger than polyester resin BUT... It is harder to cure and repair Introduction Makeup Pros and Cons Properties Uses History Future

24 The Properties of Fibreglass

25 Fibreglass is adaptable Strength depends on arrangement of glass fibres More glass fibres can be placed on specific areas to enhance strength Chemicals can be added to improve fire resistance and all sorts of other properties Introduction Makeup Pros and Cons Properties Uses History Future

26 Fibreglass is Cost Effective Same cost as Aluminium and 25% more than Mild Steel BUT... Less tooling costs No rusting Can be assembled in one piece Repairable damage Introduction Makeup Pros and Cons Properties Uses History Future

27 Fibreglass is weight-saving Fibreglass is 80% lighter than mild steel…...and 40% lighter than Aluminium! Mass of Fibreglass required to give same strength as metal Introduction Makeup Pros and Cons Properties Uses History Future

28 Fibreglass vs Metal and wood Introduction Makeup Pros and Cons Properties Uses History Future

29 Other properties of Fibreglass Non-metal :- Good insulator both against heat and electricity Easily cleaned due to smooth finish Not naturally flame retardant Different colours/textures available Introduction Makeup Pros and Cons Properties Uses History Future Can be manufactured easily and in one piece

30 Uses of Fibreglass

31 The uses of Fibreglass Introduction Makeup Pros and Cons Properties Uses History Future

32 Some specific examples... Introduction Makeup Pros and Cons Properties Uses History Future

33 The History of Fibreglass

34 Originally modelled on nature :- Bamboo Glass fibre was used by the Egyptians Introduction Makeup Pros and Cons Properties Uses History Future Dale KleistHeat treatment Fibreglass came in during WW2 (1942)

35 The Future of Fibreglass

36 The Future for Fibreglass One Problem:Microcracks can occur over time leading to failures One Solution:Make a ‘Self Healing’ Composite Introduction Makeup Pros and Cons Properties Uses History Future

37 Self-healing Fibreglass Embed Catalyst and Microcapsules of repair fluid into the composite Leads to: Reduced weathering effects Less failures More reliability Introduction Makeup Pros and Cons Properties Uses History Future

38 Self-healing Fibreglass in detail Introduction Makeup Pros and Cons Properties Uses History Future
