Experimental Investigation into the Low-velocity Impact Behavior of Thick and Thin Laminated Composites.

The low-velocity impact behavior of thick and thin unidirectional E-glass fiber-reinforced laminated composite plates with three different stacking sequences subjected to three different impact energies have been investigated. The test specimens were produced by the Vacuum Assisted Resin Injection (VARI) method in a laboratory environment. The thick specimens contained 50 layers of unidirectional E-glass fibers and the thin ones — 16 layers of unidirectional E-glass fibers. The low-velocity impact tests were carried out using a CEAST Fractovis drop-weight impact test device. The contact force–time and energy–time graphics were plotted and the experimental results were interpreted in detail. [ABSTRACT FROM AUTHOR]
