Mechanical Properties of E293/1581 Fiberglass-Epoxy Composite and of Several Adhesive Systems

摘要

Mechanical properties have been generated on E293/1581 fiberglass-epoxy composite and several different adhesive systems. Three flat panels of this composite were supplied. Several panels having adhesive joints were also supplied having the E293/E-glass fabric composite laminates bonded; to itself, to steel, and to aluminum honeycomb material. Several types of adhesives, both film and foam adhesives, were used in bonding the single lap joint panels and the composite-honeycomb sandwich panel. Tensile, flexure, and interlaminar shear data were obtained on specimens removed from the flat panels parallel to the warp fabric direction and at room temperature and 280 deg F (138 degrees C). Single lap shear tests were conducted on specimens removed from the adhesively bonded panels. Three point flexure and edgewise compression tests were conducted on specimens removed from the composite-aluminum honeycomb sandwich panel. (Author)
