Is it necessary to keep the specimen surface wet using wet cotton throughout fatigue testing of any hygrothermal aged CFRP composite laminate?

03 February 2020 0 4K Report

Conditions

1. The environmental chamber facility is not available to control the humidity level.

2. The matrix used is epoxy.

3. A scaling is getting formed on the specimen surface in environmental contact and brittleness of the matrix has increased due to hygrothermal aging at 70-degree centigrade temperature.

4. The runout limit is 106 cycles.
