Fiberglass repair

Elise and Exige clams are made of glass fiber and XXX resin. Lotus have used two methods, in the S1 and s2 Exige the glass fiber is hand laid and in the S2 elise they have employed a system that injects polyester resin and glass fiber into a mould and the sections are then assembled at Hethel. The hand layed clams are slightly thicker, heavier but stronger than the clams the use the injected method.


XXX unsure on repair implication

Saftey

when working with glass fiber


The glass fibers and resins come together to form a strong, light compersite material.

Glass fiber

comes in several forms which are used for different purposes:

tissue

Clopped strand matting

grid


Resins

several resin bases are used

polyesters

epoxy higher toughness than polyester


additional reinforcement

aluminum mesh


repair thickness


Masking off the undamaged area

mask off using plastic bin bags an area much larger than you think, resin is very messy and if it gets on the paint it will make a mess.


Surface preperation:

chemicals acetone

removing clams link

Roughing surface



Working in confined areas such inside the boot can be alkward. One method to make life easier is to prepare the fiberglass and resin on a sandwich bag and then use it like a glove to apply the fiberglass and smooth it into position.
