Elastic behaviour of plain and fibre-reinforced syntactic foams under compression

Syntactic Foams

“…Thus, the latter method was found to be more effective, as evident from the lower void content and good mechanical properties [123,124]. The compressive modulus also increased with the content of fibers in the system, except for the one containing 3.54% of fibers, which showed a lower value than other fiber-reinforced systems [125].…”

“…Karthikeyan et al found that compressive modulus and specific compressive modulus increased with an increase in fiber concentration despite the presence of voids [125]. In another study, Karthikeyan et al observed that fiber-free syntactic foams had a higher compressive strength than the fiber-bearing ones, whereas the moduli values did not differ much.…”

Effect of final pyrolysis temperature on the mechanical and thermal properties of carbon foams reinforced by aluminosilicate

“…3 with FPT of 1400 1C. This could be explained by that the modulus is usually the sum of three contributions: cell edge bending, membranes stresses and the compression of the cell fluid [11]. Surface tension can draw the phenolic resin into the cell edges in the foaming process, leaving only a thin membrane across the faces of the cells.…”

Development and characterization of epoxy syntactic foam filled with epoxy hollow spheres

“…These materials were combined together using a simple casting technique. The developed EHoS were produced in-house, thus it would provide different approach in the production of syntactic foam compared to previously studied syntactic foams which usually utilized hollow spheres manufactured by established industries [23,[35][36][37]. Because the matrix and hollow sphere were made from the same materials, the high possibility of achieving good compatibility in the system is an added advantage.…”
