Abstract

The advantages of stinging nettle fibre (Urtica dioica L.) properties as a substitute for synthetic fibres for reinforcing composite materials are its strength and lightweight compared to other natural fibres. This study aims to find the mechanical properties of hybrid composites reinforced with stinging nettle fibre based on immersion treatment of the fibres with chemical solutions. The mechanical properties studied include the hardness and toughness of the hybrid composite. This paper examines the effect of fibre immersion time in NaOH and Silane coupling agent solutions at concentrations of 3% and 9% which are used as reinforcement for hybrid epoxy resin composites. Variations of fibre immersion time in NaOH and Silane solutions: 30, 60, 90, and 120 minutes. The hybrid composite was produced by the hand lay-up moulding method. The results showed that the highest value of hardness was 88,254 VHN and toughness was 7,459 kJ/m 1562 at 9% immersion. NaOH solution can remove impurities and lignin in the fibre and the Silane coupling agent can form strong bonds because it has a hydroxy group. Based on the results of the study, it can be concluded that the hardness and toughness of the hybrid composite reinforced by stinging nettle fibre have higher hardness and toughness at 9% NaOH and Silane treatment with an immersion time of 120 minutes.
