ASTM D3171 PDF

Also, knowledge of the constituent content is required for evaluation of the quality of a fabricated material and the processes used during fabrication. Higher void volumes usually mean lower fatigue resistance, greater susceptibility to moisture penetration and weathering, and increased variation or scatter in strength properties. Knowledge of the void volume of a composite material is desirable as an indication of the quality of a composite. Scope 1. Test Method I physically removes the matrix by digestion or ignition or carbonization by one of eight procedures, leaving the reinforcement essentially unaffected and thus allowing calculation of reinforcement or matrix content by weight or volume as well as percent void volume.

ASTM D 1. Scope 1. Test Method I physically removes the matrix by digestion or ignition by one of seven procedures, leaving the reinforcement essentially unaffected and thus allowing calculation of reinforcement or matrix content by weight or volume as well as percent void volume.

Test Method II, applicable only to laminate materials of known fiber areal weight, calculates reinforcement or matrix content by weight or volume , and the cured ply thickness, based on the measured thickness of the laminate.

Test Method II is not applicable to the measurement of void volume. However, special provisions can be made to extend these test methods to filled material systems with more than two constituents, though not all test results can be determined in every case.

The suggested applications are discussed in Section 4, as well as at the start of each procedure. A procedure for correction of the results for minor changes in the reinforcement is included. Procedures A through F are based on chemical removal of the matrix while Procedure G removes the matrix by igniting the matrix in a furnace.

The presence of voids is not measured. Eq 9 and 10 assume zero void content to perform the calculation. No other units of measurement are included in this standard. 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. See Section 9 for additional information.
