Aerospace series - Analysis of non-metallic materials (cured) for the determination of the extent of cure by Differential Scanning Calorimetry (DSC)

This test method defines the procedure for the estimation of the extent of cure of certain non-metallic materials (e.g. preimpregnated and neat resin systems, adhesives) for aerospace use. The extent of cure is estimated by Differential Scanning Calorimetry (DSC) measurements of uncured (reference) and cured materials. Additional evidence on the extent of cure may be gained by combining results from this method with those obtained by other techniques.
This standard does not give any directions necessary to meet the health and safety requirements. It is the responsibility of the user of this standard to adopt appropriate health and safety precautions.

Scope

This test method defines the procedure for the estimation of the extent of cure of certain non-metallic

materials (e.g. preimpregnated and neat resin systems, adhesives) for aerospace use. The extent of cure

is estimated by Differential Scanning Calorimetry (DSC) measurements of uncured (reference) and cured

materials. Additional evidence on the extent of cure may be gained by combining results from this method

with those obtained by other techniques.

This standard does not give any directions necessary to meet the health and safety requirements. It is the

responsibility of the user of this standard to adopt appropriate health and safety precautions.

Symbols and definitions
For the purposes of this document, the following symbols and definitions apply.

The determination of these parameters shall be agreed upon between manufacturer and purchaser in

case of non-ideal curves or different instrument types.
3.1
curing reaction (see Figure 1)
θ is the heating rate, in degrees Celsius or Kelvin by minutes;
∆H is the reaction enthalpy, in Joules by grams;

∆H is the reaction enthalpy corrected to 100 % resin content, in Joules by grams;

100
A-curve is the reference reaction curve for uncured material;
B-curve is the reaction curve for an already (semi-) cured sample.
3.2
calibration (see 6.6)
T is the melting temperature, in degrees Celsius or Kelvin
∆H is the enthalpy of fusion, in Joules by grams
Principle of the method

Differential Scanning Calorimetry (DSC) measures the temperatures and the heat flow associated with

transitions in materials as a function of time and temperature.
