SONIC FATIGUE TOLERANCE OF GLASS FILAMENT STRUCTURE: VOLUME II. EXPERIMENTAL RESULTS.

Abstract

Sonic fatigue experimental test results on a series of sixty flat rectangular glass fiber sandwich test panels are presented and discussed. The panels were of the fluted core (corrugated) type, had nominal overall dimensions of 24 in. x 30 in. x 0.45 in., and a nominal surface weight of one pound per square foot. The fluted core glass fabric (181 and 151S glass) was of the integrally woven variety. A vacuum process was employed to impregnate the glass cloth with resin. Twenty each of three types of panels were sonic fatigue tested using a discrete frequency siren, five identical panels at four different sound pressure levels, to provide three S-N (Sound Pressure Level Vs. Cycles to Failure) plots. Twenty aluminum skin-stringer panels of the same overall dimensions and surface weight were similarly tested for control. (Author)
