ignition near the surface of the liquid or within the vessel used
3.7
gel time
interval of time, in connection with the use of synthetic thermosetting resins, extending from the introduction of
an initiator and a catalyst into a liquid resin system until the interval of gel formation/solidification

3.10
monomer
relatively simple substance, usually containing carbon and of low molecular mass, which can react to form a
polymer by combination with itself or with other similar molecules or substances
Note 1 to entry: To be distinguished from the term reactive monomer, which within the context of unsaturated
polyester/vinyl ester is defined as a substance with unsaturated groups which can undergo cross-linking reactions with the
unsaturated polymers through the curing reaction.
3.11
resin
the uncured liquid material that is used as matrices to bind together the
reinforcement materials in a fibre-reinforced composite product
3.12
styrene
colourless liquid produced from the catalytic dehydrogenation of ethylbenzene which is easily polymerized by
exposure to light, heat or a peroxide initiator
Note 1 to entry: The main reactive monomer used in unsaturated polyester/vinyl ester materials.
3.13
unsaturated polyester
thermosetting resins of polyester molecules, dissolved in a reactive monomer (e.g. styrene) capable of
copolymerisation with the polyester molecules
Note 1 to entry: The polyester molecules are condensation products of polyols (e.g. ethylene glycol, dipropylene
glycol, glycerol) and saturated/unsaturated difunctional carboxylic acids/anhydrides (e.g. terephthalic acid, phthalic
anhydride, fumaric acid, maleic anhydride) and/or cyclic unsaturated hydrocarbons (e.g. dicyclopentadiene).
Note 2 to entry: At least one of the acids/anhydrids is unsaturated (usually maleic anhydride/fumaric acid is used).
3.14
vinyl ester resins
thermosetting resins of vinyl ester molecules, dissolved in a reactive monomer (e.g. styrene) capable of
copolymerisation with the vinyl ester molecules

epoxy) with an unsaturated monocarboxylic acid (e.g. methacrylic acid).
3.15
viscosity
measure of the resistance to flow due to internal friction when one layer of fluid is caused to move in
relationship to another layer
Note 1 to entry: In the context of thermosetting resins for the FRP (Fibre-Reinforced Plastic) industry, viscosity is one
of the important parameters that express the ability of a resin to flow in reinforcements and release entrapped air often
formed during the application a production process.
3.16
water absorption
moisture absorption
amount of water absorbed by a material under specified test conditions
Note 1 to entry: The conditions may be immersion in water or exposure to a humid atmosphere, in the latter case the
