Standard Test Method for
Matrix Solids Content and Matrix Content of Composite
Prepreg1

This standard is issued under the fixed designation D 3529/D 3529M; the number immediately following the designation indicates the
year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last
reapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

This standard has been approved for use by agencies of the Department of Defense.

1. Scope

1.1 This test method covers the determination of the matrix
solids content and matrix content of composite material
prepregs. Volatile content, if appropriate and required, is
determined by means of Test Method D 3530/D 3530M.

1.2 This test method focuses on thermosetting matrix material systems for which matrix may be extracted in an organic
solvent. However, other, unspecified reagents may be used with
this test method to extract other matrix material types for the
same purposes.

1.3 This test method does not distinguish between hybrid
reinforcements or matrices. Its use with hybrids is limited to a
determination of total reinforcement or matrix, or the use of a
standard factor to be used as the weight of a particular
reinforcement or matrix constituent.

1.4 Alternate techniques for determining matrix and reinforcement content include Test Methods C 613/C 613M
(Soxhlet extraction) and D 3171 (meant typically for laminates; covering matrix digestion or combustion).

1.5 The values stated in SI units are to be regarded as
standard.

1.6 This standard does not purport to address all of the
safety concerns, if any, associated with its use. It is the
responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary information is given in 8.2.4 and 8.2.5
