Abstract
Utilization of citric acid as natural binder for nonwood composite is still limited Therefore this study investigated the physical and mechanical properties of particleboard made from bamboo using citric acid as natural binder Three bamboo particles ie petung bamboo Dendrocalamus asper wulung bamboo Gigantochloa atroviolacea and apus bamboo Gigantochloa apus were used as raw materials in this research Citric acid contents were set at 0 15 and 30 wt based on airdried particles Two classifications of petung bamboo particle sizes coarse and fine particles were used in this research The particleboards were also made as single layer and three layer boards with variation of layer compositions The results showed that addition of citric acid could significantly improve the dimensional stability and mechanical properties of the boards while bamboo species did not significantly affect the properties of boards Fine particles provided higher internal bond strength of the particleboard than coarse particles due to bigger contact area among fine particles Single layer particleboard provided higher internal bond strength compared to the three layer ones The properties of citric acidbonded bamboo particleboard in this research could meet the requirements of the Japanese Industrial Standard for particleboard A 5908 Fourier transform infrared analysis indicated that the peak at around 1734 cm−1 was hardly recognized in binderless board however it clearly appeared in citric acidbonded particleboards As a result of reaction between citric acid and bamboo good properties of particleboards could be obtainedThe authors are grateful to Directorate General of Higher Education Ministry of National Education Indonesia and Universitas Gadjah Mada Research Grant No LPPMUGM/1379/LIT/2013 and LPPMUGM/462/LIT/2014 The authors also thank the student Ari Puspa Yudha for her assistance in fabrication of the composite
