Glass Fiber Composite Specimen Preparation

Metallographic etchant database

Glass reinforced composites are very useful materials, however microstructural preparation can be tricky. The best approach is to minimize the amount of cracking and chipping in the fibers as early in the preparation stage as is practical. This is accomplished by starting with 320 grit SiC or finer. For rough and final polishing, the use of a resilient polishing pad such as Black Chem, in combination with polycrystalline diamond and SIMAT colloidal silica produce a damage free surface ready for examination.
