Study on Low-Velocity Impact Performance of Chemical Treated Flax Fibre-Reinforced Aluminium 6082 Laminates

The experimental studies of drop weight and Izod impact test of FFAL (flax fibre aluminium laminate) are presented in the research. The materials taken for the study are plain woven flax and aluminium lamina with epoxy resin as an adhesive material. Alkaline with diluted epoxy chemical treatment is added to flax, and aluminium is treated with NaOH to strengthen the binding between the fibres and metal. The FFAL was prepared by hand layup method followed by compression moulding technique. The low-velocity and Izod impact tests were conducted for treated and untreated samples. The outcomes exhibited that the increase in the impact strength of 40% and energy absorption capacity of low-velocity impact strength also improved for the treated sample. The experimental damage of low-velocity and Izod impact test results are also examined.
