Flexural property study of multiaxial fiber reinforced polymer sandwich panels with pultruded profile cores
Abstract This study investigates the bending performance of a new type of composite sandwich panels with pultruded profile cores, and multiaxial glass fiber reinforced polymer (GFRP) facial sheets and webs between the profile cores. The influences of the position and number of fiber cloth layers on the bending properties of the sandwich panel are also studied. The failure modes, load–deflection behavior, and load–strain relationships are compared using four-point bending tests. The results show that wrapping multiaxial fiber cloth can change the brittle failure characteristics of the pultruded profiles, and that the multiaxial FRP surface and uniaxial pultruded profiles can operate effectively. The completely wrapped fiber cloth method improves the bending performance of the sandwich plate.
Highlights A new type of composite sandwich panel was investigated. Pultruded profiles (core) and multiaxial GFRP (facial sheets, webs) were used. Four-point bending test were conducted and panel properties were quantified. Multiaxial fiber cloth wrapping changed the brittle failure profile characteristics. Complete fiber cloth wrapping yielded improved bending performance.
