Micromechanical modelling of syntactic foam [PDF]

Composites Part B: Engineering, 2020
Abstract A combined numerical-experimental method that enables accurate prediction of not only the elastic moduli and tensile failure strengths of syntactic foams, but also accounts for the experimentally observed scatter in these measurements is presented.

Densification mechanics of polymeric syntactic foams [PDF]

Composites Part B: Engineering, 2022
In this paper, a fundamental understanding of the densification mechanics of polymeric syntactic foams under compressive loading is established. These syntactic foams are closed cell composite foams with thin-walled microballoons dispersed in a matrix (resin) whose closed cell structure provides excellent mechanical properties, like high strength and ...

Static and impact responses of syntactic foam composites reinforced by multi-walled carbon nanotubes

Journal of Materials Research and Technology, 2020
The incorporation of multi-walled carbon nanotubes (MWCNTs) into syntactic foams (hollow glass microspheres bonded to a polymer matrix) can enhance the mechanical performance of syntactic foams.

Hydrostatic strength of hollow glass microspheres composites: Influencing factors and modelling

Composites Part C: Open Access, 2022
This study deals with the hydrostatic strength of hollow glass microspheres composites, commonly known as syntactic foams, using model materials made of 0.15 g/cm3 microspheres with 3 types of matrix, two epoxies and one paraffin.

Tensile properties of all-polymeric syntactic foam composites: Experimental characterization and mathematical modelling [PDF]

Composites Part B: Engineering, 2021
All-polymer syntactic foams are studied under large strain cyclic and monotonic tensile loading in order to reveal their tensile stress-strain behaviour, recoverability, tensile strength, and elongation at break.

Water Impact of Syntactic Foams [PDF]

Materials, 2017
Syntactic foams are particulate composite materials that are extensively integrated in naval and aerospace structures as core materials for sandwich panels. While several studies have demonstrated the potential of syntactic foams as energy absorbing materials in impact tests, our understanding of their response to water impact remains elusive.

Functionally-Graded Metallic Syntactic Foams Produced via Particle Pre-Compaction

Metals, 2020
This paper introduces a novel functionally graded metallic syntactic foam. The investigated foams are manufactured while using infiltration casting where molten A356 aluminum flows into the interstitial voids of packed expanded perlite (EP) particle beds.

X-ray microtomographic characterization and quantification of the strain rate dependent failure mechanism in cenosphere epoxy syntactic foams [PDF]

, 2016
This work investigates the failure mechanism in cenosphere epoxy syntactic foams at the quasi-static and dynamic strain rates. Split-Hopkinson pressure bar experiments are controlled to stop dynamic deformation of the foams at various strain stages.
