Chemistry Fiber Glass Assignment Help!?

I have this chemistry assignment about the properties of fiber glass. I was wondering if anyone could explain the chemical properties and structures of the resin, catalyst and glass fibers, as well as the chemical reaction that takes place when the catalyst is added to the resin.

Also, how differant amount of resin could affect the properties of the final product.
 
resin is polyester - made from reacting phalic anhydride and maleic acid. It forms long chain structures with styrene as a monomer and diluent. Cross linking reaction is initiated normally with peroxide (eg: Benzoyl peroxide) whereby the long polyester chains react with the styrene to form a strong rigid structure.
In itself it can be brittle so the reinforcement of glass fibre strands makes up for a very light and tough composite.
Properties affected by (a) type of polyester resin used
(b) ratio of styrene to polyester
(c) type of catalyst used influencing the cross-link density
(d) ratio of resin to glass fibres
include tensile strength, flexural strength, toughness, impact resistance, density.
