“…Figure 13.10 shows that diameter to wall thickness ratios can be quite high. These spheres can be used in a number of applications, including lightweight and self-lubricating composites, in a wide variety of materials [7]. Carbon spheres can be coated with a ceramic such as silicon carbide or a metallic coating in order to prevent undesired reactions, like the formation of aluminium carbide, and to help improve wetting between the matrix and the reinforcement.…”

“…Syntactic foams are a class of closed-cell foam which is manufactured by filling a polymeric matrix with hollow spheres called microspheres or micro balloons [1,2]. They have been widely used in several engineering applications due to their low moisture absorption, good thermal insulation, and excellent strength to weight ratio, vibration isolation, and low radar cross-section properties [3][4][5].…”

Syntactic foams are closed cell structured foam materials and present improved properties for lightweight and high performance material requests. They have been widely used in naval, aeronautical, aerospace, civil, industrial, and automotive engineering applications on account of their good acoustical attenuation, excellent strength to weight ratio, vibration isolation, dielectric properties. In this study, a novel high strain rate sensitive syntactic foam was developed. A rigid polyurethane resin was used as a binder material. Glass bubbles were used as an additive for producing cell structure. Elastomeric silicone rubber resin were used to change elastic properties of the foam as an additional binder material. Quasistatic compression properties and high strain rate compression properties were obtained by using Instron Universal Tensile-Compression Machine and Split Hopkinson Pressure Bar experimental setup respectively. The results show that developed foams are low dense and very high strain rate sensitive materials. Consequently, developed foam can be used for the blast, impact or ballistic mitigation purpose as a coating material.

“…The hollow particles can be made of carbon, ceramics, or glass, while the matrix is often made of metals or polymers [6][7][8][9]. Previous studies [10][11][12] have shown that the properties of the syntactic foams can be tailored by varying the volume fraction and the wall thickness of the hollow particles. Besides, another phase of materials such as discontinuous fibers or nanoclays has been successfully embedded to further improve the performance of the composites [13][14][15][16][17].…”

The failure behavior of the syntactic foams is investigated based on a three-dimensional (3D) micromechanical finite element (FE) model, by varying the volume fraction, the wall thickness of the hollow particles, and the interfacial strength. The maximum princi pal stress criterion is adopted to determine the state (damaged or undamaged) for both interface and matrix. Material property degradation is used to describe the mechanical behavior of those damaged elements. The current model can reasonably predict the ten sile strength of the syntactic foams with high volume fractions (40%-60%). The failure mechanism of the syntactic foam under uniaxial tension is captured by analyzing the stress-strain curves and the contours of damaging evolution process. Results from the quantitative simulations demonstrate that the tensile strength of the syntactic foam can be improved effectively by enhancing the interfacial strength.
