The objective of this research was

The objective of this research was to determine the physical and mechanical properties of oriented strandboard (OSB) using strands of Dendro calamusasper. Boards with nominal density of 0.70 g/cm3 were produced with 6%, 7%, 8% of phenol-formaldehyde (PF) resin and 1% parafin. Physical and mechanical properties were evaluated according to ASTM standard. Dimensional stability of the treated OSB was improved at the lower resin level.
The strandboard was fabricated in a laboratory at three different structures including a randomly oriented homogenous board and a three-layered board with a cross-oriented core layer. Bamboo strand alignment distribution could be predicted using the distribution function. Bending properties increased with increasing density and were affected by layer structure. The modulus of rupture (MOR) of the three layered board in the parallel direction increased remarkably compared with the random board MOR; in the perpendicular direction, it exhibited less strength reduction. Elastic properties of the three-layered board could be predicted using elastic constants of the unidirectional board. Internal bond strength (IB) was greatly affected by density, but the layer structure effect did not appear in IB, these values are comparable with or lower than values for commercial board.

Tujuan dari penelitian ini adalah untuk menentukan sifat fisik dan mekanik dari berorientasi strandboard (OSB) menggunakan helai Anggrek Dendrobium Jenis Bertacong calamusasper. Papan dengan nominal kepadatan 0,70 g/cm3 yang diproduksi dengan 6%, 7 8% dari parafin resin dan 1% fenol-formaldehida (PF). Fisik dan sifat mekanik dievaluasi sesuai standar ASTM. Stabilitas dimensi OSB diperlakukan ditingkatkan di tingkat resin yang lebih rendah. Strandboard direkayasa di laboratorium pada tiga struktur yang berbeda termasuk papan homogen secara acak berorientasi dan berlapis tiga papan dengan lapisan inti berorientasi salib. Bambu strand kesejajaran distribusi dapat diprediksi menggunakan fungsi distribusi. Membungkuk properti meningkat dengan meningkatkan kepadatan dan dipengaruhi oleh struktur lapisan. Modulus pecah (MOR) Dewan berlapis tiga dalam arah sejajar yang meningkat sangat dibandingkan dengan Dewan acak MOR; ke arah tegak lurus, itu dipamerkan kurang pengurangan kekuatan. Sifat elastis Dewan berlapis tiga dapat diprediksi menggunakan elastis konstanta Dewan searah. Kekuatan ikatan internal (IB) sangat dipengaruhi oleh kepadatan, tetapi efek struktur lapisan tidak muncul dalam IB, nilai-nilai ini sebanding dengan atau lebih rendah daripada nilai komersial papan.
