The development of environmentally friendly composite materials is important because it is a global demand. However, using natural materials does not rule out the possibility of a decrease in quality during use in a wet environment and in conditions of impact defects. This paper analyzes the post-impact bending strength of sandwich composites with woven bamboo reinforcement after being immersed in seawater. Sandwich composites are made by laminated polyurethane rigid foam sheet with polyester resin and bamboo-fiberglass woven hybrid reinforcement. To provide defects in the sandwich composite, dropweight impact was carried out, then it was immersed in seawater and a bending test was carried out. The highest average bending strength of sandwich composites occurs in formations with a higher amount of fiberglass. The performance of maintaining post-impact bending strength is better in composites with more bamboo laminate formations, the decrease in post-impact bending strength is only 2.6%. The post-impact bending strength of sandwich composites in wet conditions has a lower value than in dry conditions. The longer the immersion of the sandwich composite in seawater after impact, the smaller the bending strength.

The manufacturing process of cement results in the depletion of limited natural resources, consumption of excess energy and also leads to significant levels of carbon dioxide emission in the atmosphere. Consequently, researchers all over the World are concentrating their efforts in finding alternative materials that can replace cement on the long run. In this view, the focus has been turned onto utilising sugarcane bagasse ash as a source of raw and eco-friendly substitute material. Moreover, the possibility of using sugarcane bagasse ash in concrete have long been debated. The outcome of the experiments have showed positive and encouraging results especially for the mechanical and durability properties of concrete samples. The substitution of sugarcane bagasse ash in concrete would not only provide an economic relief, but also help to create a sustainable and pollution-free environment as the disposing of this waste creates many inconveniences to living organism.
