Abstract

ABSTRACT
Low velocity impact tests have been conducted on paper honeycomb sandwich
panels. Two panel thicknesses with span length of 100 mm are used; these are 35
mm and 41 mm, respectively. The dynamic behavior of each paper honeycomb
thickness is investigated using two types of indentors: hemispherical and bar. The
effect of indentor, and specimen length are studied. This includes the pattern of loaddisplacement
curve collapse load and energy absorbed. It concludes that the
dynamic collapse load on 41 mm thickness for hemispherical indentor increases by
5% compared with 35 mm. The impact energy absorbed for hemispherical indentor
increases by 36%.
