Ky. Lee et Ed. Case, EFFECTS OF ADHESION ON THE EFFECTIVE YOUNGS MODULUS IN GLASS SLIDE GLUE LAMINATES .1. EXPERIMENTS, Journal of Materials Science, 31(9), 1996, pp. 2241-2251
Bond-phase defects in laminates can affect the mechanical properties o
f laminate composites. In this study, the effects of adhesion area, nu
mber of glue spots, and bond thickness on the effective Young's modulu
s of adhered microscope glass slides have been investigated. Three dif
ferent adhesive agents (super glue, epoxy cement, and epoxy resin) wer
e used to explore the effect of bond-phase defects upon adhesion in la
minates. The elastic moduli of single glass slides, unadhered glass sl
ide pairs, glass slide/glue composite specimens and epoxy resin specim
ens were non-destructively determined by a sonic resonance technique.
The change of Young's modulus of adhered glass slides was monitored wh
ile adhesion area per cent ranged from 0.35%-100%. Trends in the Young
's moduli of glass slide/glue composite specimens have been analysed b
y a least-squares best-fit procedure to two empirical equations. Quali
tative explanations for the observed trends are discussed in this pape
