Fire resistant composite laminates from GFRP reinforced natural fibers.

The development of composite has spread in every industrial line. Composite is a solution to the demand for material with superior characteristics. One of the most needed characteristics is burning resistance. Extensive composite application encourages continuous innovation, including in terms of the use of natural fibers as a reinforcement. Research related to natural fibers is needed as an alternative to giving birth to environmentally friendly and economical composite. One of the natural fibers that can be utilized is bamboo fiber. Plants with very high growth rates are expected to be a sustainable alternative. The purpose of this study is to manufacture and test the burn resistance and mechanical property of the glass plate/bamboo fiber reinforced composite. There are 3 types of plates that will be manufactured, namely epoxy plates, glass fiber reinforced composite, and glass/bamboo fiber reinforced composite. glass fiber reinforced composite is manufactured with 4 glass fiber layers. Hybrid composites are manufactured with layers in the form of 2 glass fiber layers, bamboo layers, and 2 glass fiber layers in sequence. The GFRP and hybrid composites manufacturing method is by vacuum assisted resin transfer molding. The treatment of the 3 types of plates is burning with a duration of 15, 30, 45, and 60 seconds. The burnt results will be cut and tested according to ASTM D790. The results of the burn and bending tests show that the glass plate/bamboo fiber reinforced composite shows the highest burn resistance and the smallest decrease in bending power due to burnt treatment compared to the other 2 types of plates.
