The static impact and vibration behaviour of frp honeycomb core sandwich composites

Abstract

Sandwich structured composites are a special class of composite newlinematerials which have become very popular due to their high specific strength newlineand bending stiffness Sandwich composites are used in a wide variety of newlinestructural applications largely because of their relative advantages over other newlinematerials Sandwich Constructions which consist of two relatively thin and newlinestiff faces bonded to a low density core offer many benefits such as high newlinebending stiffness good thermal and acoustic insulation properties and high newlinespecific energy absorption Due to increasing global competition a number of newlineindustries have a strong need to develop an advanced honeycomb core for newlinelight weight sandwich panels with significantly higher specific strength and newlinebending stiffness than presently available newline newline
