摘要：

The disadvantages of natural fiber reinforced laminate composite materials are reviewed from their mechanical properties (impact toughness, flexibility), so they do not meet the requirements to be applied as raw materials for parquet flooring. Parquet flooring made of Stone Plastic Composite (SPC) and wood plastic composite (WPC) also have limitations. Namely, they contain heavy metals, have low absorption capacity, and are not heat resistant, so they are not suitable for outdoor use, are easy to peel, and are not environmentally friendly. The characterization of polyester composites reinforced with hybrid fibers of Musa Acuminata Stem Fiber (MASF)-Bamboo fiber (BF) with a Polyurethane Resin (PR) matrix has been carried out. The variations of bamboo types used are apus bamboo (BA) (Gigantochloa apus) and wulung bamboo (BW) (Gigantochloa atroviolacea). This study aims to develop the impact toughness and flexibility of laminate composites. The MASF and BF volume fraction variations were: 5%: 25%, 10%: 20% and 15%: 15%. The results showed that the use of BA bamboo fiber in laminate composite materials reinforced with MASF-BF hybrid fibers with PR had better mechanical properties (impact toughness and flexibility) compared to using wulung bamboo fiber, so it is important to be further developed as a material for making parquet flooring. 2024 Seventh Sense Research Group.
