scope:

Specifies two methods for the determination of the cure characteristics of fibre-reinforced thermosetting moulding compounds and prepregs. The characteristics measure are: - the heat generated by the exothermic reaction; - the thermal expansion of the compound accompanying the rise in temperature; - the shrinkage due to the curing reaction. The methods are applicable to all compounds comprising thermosetting matrices reinforced with fibres. The major field of application is compounds based on UP resins like SMC (prepregs), BMC and DMC.
