Effect of Hostile Solutions on Composites Laminates Subjected to Low and High Velocity Impact Loads

Composite structures can be exposed to different hostile environments, which cause degradation of their mechanical properties. However, this subject is not completely understood. Therefore, the aim of the present work is to study the low velocity impact and the response at high strain rates of carbo...

More Information
Summary:Composite structures can be exposed to different hostile environments, which cause degradation of their mechanical properties. However, this subject is not completely understood. Therefore, the aim of the present work is to study the low velocity impact and the response at high strain rates of carbon/epoxy laminates, after immersion into hydrochloric acid (HCl) and sodium hydroxide (NaOH). From the experimental tests, it is very clear that exposure to corrosive solutions affects significantly the impact strength, but their effects are strongly dependent of the exposure time. Finally, alkaline solutions show to be more aggressive.
