Self-healing composite sandwich structures

Smart Materials and Structures, 2007
Impact damage can degrade the flexural strength of composite sandwich structures by over 50% due to a loss of skin support inducing localized skin buckling. Various self-healing methodologies have been applied to laminated composites but the concept of delivering a healing agent from a remote reservoir to a region of damage via a vascular network ...

Partially Composite Sandwich Panel Deflections

Journal of Structural Engineering, 1995
A continuum model for evaluating partially composite insulated concrete sandwich panel deflections with discrete shear connectors due to differential volume changes such as those caused by differences in temperature between the wythes is evaluated for accuracy by comparison with finite-element analysis.

Assessment on the ageing of sandwich composites with vinylester-based composite faces and PVC foam core in various harsh environments

Composite structures, 2019
The behaviour of moisture absorption and evolution of various mechanical properties for the sandwich composites immersed into two humid conditions: seawater with 30°C (SWL) and purewater with 80°C (PWH) have been examined by Ding et al . [13] .

Sandwich PZT/polymer composite transducer

Ferroelectrics, 1983
Abstract Sandwich composite materials consisting of one PZT/polymer middle layer and two solid PZT surface layers have been tested for use as a hydrophone and NDT transducer. The effects of the thick fraction of solid PZT surface layer, of filling porous layer with polymer and hydrostatic pressure on the electromechanical properties are described.

Self-healing sandwich composite structures

SPIE Proceedings, 2012
Previous research demonstrated that a thin self-healing layer is effective in recovering partial sandwich composite performance after an impact event. Many studies have been conducted that show the possibility of using Fiber Bragg Grating (FBG) sensors to monitor the cure of a resin through strain and temperature monitoring. For this experiment, FBG

Parametric investigations of mechanical properties of nap-core sandwich composites

Composites Part B: Engineering, 2019
The focus of this paper lies on the sensitivity of the nap-core sandwich – a novel kind of structural composite – to changes of its parameters. First, the fabrication, properties, and applications of the nap-core sandwich are briefly presented.

Indentation of composite sandwich beams

The Journal of Strain Analysis for Engineering Design, 1996
Indentation of a sandwich beam is analysed as linear elastic bending of the top skin on a rigid-perfectly plastic foundation (the core). The theoretical predictions of fracture load from this simple theory are shown to be in good agreement with experimental results from indentation tests on strips of sandwich panel, with glass-fibre-reinforced plastic

Characterization of Wood-Polypropylene Composite Sandwich System

Journal of Composite Materials, 2000
A new wood-polypropylene composite sandwich was made by bonding unidirectional continuous glass fiber reinforced polypropylene (UCGPP) composite to oak wood using a thermoplastic tie layer. In order to evaluate the practical utility of wood-composite sandwich systems, the effects of moisture changes in both continuous and cyclic manner were ...
