The thermal expansion behavior of three epoxy-fiberglass composite specimens was measured from 20 to 120/sup 0/C (70 to 250/sup 0/F) using a fused quartz push-rod dilatometer. Billets produced by vacuum impregnating layers of two types of fiberglass cloth with an epoxy resin were core-drilled to produce cylindrical specimens. These were used to study expansion perpendicular and parallel to the fiberglass layers. The dilatometer is held at a preselected temperature until steady-state is indicated by stable length and temperature data. Before testing the composite specimens, a reliability check of the dilatometer was performed using a copper secondary standard. This indicated thermal expansion coefficient (..cap alpha..) values within +-2% of expected values from 20 to 200/sup 0/C.
