ASTM C613/C613M-97

Standard Test Method for Constituent Content of Composite Prepreg by Soxhlet Extraction

SCOPE
1.1 This test method covers a Soxhlet extraction procedure to determine the matrix content, reinforcement content, and filler content of composite material prepreg. Volatiles content, if appropriate, and required, is determined by means of Test Method D3530/D3530M.
