A Novel High Strain Rate Sensitive Rigid Polyurethane Resin Based Syntactic Foam

5th International Advances in Applied Physics and Materials Science Congress Exhibition (APMAS2015), Muğla, Türkiye, 16 - 19 Nisan 2015, ss.248

Syntactic foams are close 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 produce cell

structure. Elastomeric silicone resin were used for change elastic properties of the foam as an

additional binder material. Quasi static compression properties and high strain rate compression

properties were obtained by using Instron Universal Tensile-Compression Machine and Split

Hopkinson Pressure Bar experimental set up respectively. The results show that, developed foam is

very high strain rate sensitive material. The strength raise depend on strain rate was obtained more

than widely used Polyurea strain rate sensitive coating material. Consequently, developed foam can

be used for blast, impact or ballistic mitigation purpose as a coating material.
