Effect on mechanical properties by partial replacement of the glass with alkali-treated flax fiber in composite facesheet of sandwich structure

Sandwich structures made of glass-reinforced composite facesheet (FS) and honeycomb core are using in many load-carrying applications. This study aims to reduce the dependency on synthetic materials FS sandwich structure. Recently, there has been rapid growth research innovation hybrid achieve comparable performance cost, weight, environmental impact. In present research, mechanical properties (tensile, axial compression, flexural) with flax/glass structure were investigated. The was fabricated different ratios glass alkali-treated flax fiber. non-hybrid composites for comparison purposes. overall results showed potential reinforcement improve structural compared revealed promising composite. by replacing 25% weight fiber achieved 96% compression strength 92% flexural facing stress H2 outer only 6% lower stiffness than when normalized compared.
