Abstract

Bamboo is a lightweight and high-strength raw materials that encouraged researchers to investigate and explore, especially in the field of biocomposite and declared as one of the green-technology on the environment as fully accountable as eco-products. This research was to assess the technical feasibility of making single-layer experimental Medium-Density Particleboard panels from the bamboo waste of a three-year-old (Dendrocalamus asper). Waste materials were performed to produce composite materials using epoxy resin (C21H25C105) from a natural treatment by soaking with an average of pH 7.6 level of sea-water. Three different types of MDP produced, i.e., bamboo waste strip MDP (SMDP), bamboo waste chips MDP (CMDP) and bamboo waste mixed strip-chips MDP (MMDP) by following the same process. The experimental panels tested for their physical-mechanical properties according to the procedures defined by ASTM D1037-12. Conclusively, even the present study shows properties of MDP with higher and comparable to other composite materials; further research must be given better attention as potential substitute to be used as hardwood materials, especially in the production, design, and construction usage.

Abstract

In this study, the effectiveness of mango polyphenol (MPP) powder in seawater pH 7.4 as a natural treatment on the mechanical properties of unidirectional full culm bamboo (Dendrocalamus asper) was investigated. Our observations are explained through the changes in MPP percentage of 5, 10, and 20 of the raw material upon treatment, where the 10% amount of MPP are dominant in compressive strength with 43.83 MPa at the top part (nodal), 10% amount of MPP in compressive strength with 47.13 MPa at the middle part (non-nodal), and 5% in flexural strength with 43.07 MPa at the top part. The treatment process combining sea-water absorption plus mango polyphenol powder is more effective in improving mechanical properties with MPP variations than using them alone. Finally, materials identified as having favorable effects on full bamboo culm.
