摘要

Syntactic foam composites containing 0,0.9,1.76,2.45,3.54,and 4.5 vol %of E-glass fibers in the form of chopped strands were fabricated and subjected to compression testing.It was found that the compressive strength values generally increased with fiber content except for the 3.54% fiber-bearing cast slab,which recorded lower values.This lone exception was due to the difference in processing route adopted in fabricating this particular fiber-bearing foam.Also noticed was the fact that the compressive strength of the 0.9 vol %fiber-bearing system was lower compared to the fiber-free bearing foam compared to that seen in the unreinforced foam.
