Abrasion resistance of a carbon fiber reinforced composite based on a nanoclay epoxy nanocomposite matrix

In this paper, the abrasion resistance of a carbon fiber composite based on epoxy nanocomposite matrix filled with layered-silicate clay nanoparticles was evaluated. In the first step of the work, the clay-epoxy nanocomposite was first studied to assess the dispersion and the performance, and then to select the best content for the fiber composite production. The nanocomposite mixture was prepared by finely dispersing clay nanoparticles into the epoxy monomer through mechanical stirring, then the hardener was added. After this step, the fiber reinforced composite was produced by vacuum infusion, and then the properties were evaluated. The abrasion resistance has been assessed using different approaches. A test was specifically designed to simulate the impact of abrasive powders which could potentially be found in the atmosphere and crash into aircraft or air vehicles (such as for instance volcanic ashes). The results showed that the presence of nanoclay reduces the weight loss of the sample with the impacted surface, which can be clearly correlated to a damage reduction. Highlights: Sandblasting tool made to mimic impact of abrasive powder on composite surface Presence of nanoclay does not significantly affect the vacuum infusion process Layered-silicate nanoparticles lead to improve composites abrasion resistance.
