Frequency-dependent viscoelastic crosslinked polyether elastomer and nano-silica synergistically enhance the impact resistance of Kevlar laminates

Key Points

• Impact resistance increases with the introduction of viscoelastic crosslinked polyether elastomer and nano-silica, showing significant improvement.
• Results highlight a greater than 30% enhancement in resistance compared to conventional materials.
• Assessment using a combination of viscoelastic properties and nano-silica ensures effective crosslinking in composite materials.
• This improvement suggests interesting applications in protective gear, although full modeling in real-life scenarios remains necessary.
