The water absorption test using rectangular specimens
were cut with the dimensions of 30 · 28 mm (length · -
wide). The experiments were performed using test samples
unsealed on the sides (ASTM D570), in an attempt to replicate
the most aggressive in-use water absorption condition.
The sample was oven dried at 50 C for 24 h to a
The dynamic mechanical properties of the resin and
composites were measured using a Mettler Toledo Model
DMA 861 under the flexural mode of testing. The dimensions
of the specimens were 50 mm · 13 mm · 4 mm. The
heating rate was set at 5 C/mm.
