“…Ten replicates of compressed OPT were produced. The compressed OPT was hot pressed using a laboratory Molding Test Press, Model Fabricate GT-7014-A30, for 60 min at 200 °C and a pressure of 11.16 MPa (Salim et al 2012). Compressed OPT without steaming treatment was produced to compare the effect of steaming to the compressed OPT.…”

“…Considering the fact that biomass from oil palm trees is expected to double in the near future, it would bring a beneficial economic return to Malaysia if this material were efficiently used (Sulaiman et al 2009). Although many studies have reported on the use of oil palm trunks for laminated veneer (LVL), pulp and paper, and different types of composites (Dahlan 2000), very limited information is available on the use of oil palm for compressed lumber (Salim et al 2012) The concept of wood densification dates back to the early 1400s (Seborg et al 1962) and is used for strength enhancement. Properties of compressed lumber from different species have been investigated in past studies (Hsu et al 1988;Inoue et al 1993aInoue et al , 1996Kawai et al 1992).…”

Compressed lumber is considered to be a superior structural material due to its uniform properties and higher strength than other solid timbers. This study presents the effect of steaming on some properties of compressed lumber of oil palm (Elaeis guineensis) trunks (OPT). The specimens were steamed at a temperature of 130 ⁰ C for 2 hours before being compressed in a hot press and evaluated for their physical and mechanical properties. Compressed OPT without steaming was used as a comparison sample to compare the effect of steaming on compressed OPT. The average modulus of rupture of steamed compressed OPT samples was 31.36 MPa, which was 8.7% higher than the compressed OPT without steaming samples. The modulus of elasticity was determined to be 8919 MPa, 9.9% higher than the compressed OPT samples. Steaming enhanced the dimensional properties of the samples. Thickness swelling and water absorption of the steamed compressed OPT samples were 6.57% and 33.84%, respectively, lower than those of the samples without steaming. Some other properties such as compression strength, dynamic bending strength, and the compression and recovery ratios were also evaluated. Scanning electron micrographs taken from the cross section of the samples showed a clear difference between the compressed and uncompressed oil palm.

“…Upon steaming, the hemicelluloses, cellulose, starch, lignin, and some extractives were partially degraded. Salim et al (2012) found that steamed samples experienced less biological deterioration compared to non-steamed samples. This could be due to the lesser amount of readily available food favorable to microorganisms in the samples.…”

“…Samples were subjected to steam in an autoclave chamber at 130 °C for 120 min. The optimum manufacturing condition was based on previous research by Salim et al (2012). The steamed samples were dried in the oven of 50 °C to reduce water content before being subjected to hot pressing.…”

“…Compreg is a resin-treated, compressed wood, whereas Staypak is not impregnated with any resin (Seborg et al 1962). Salim et al (2012) optimized the manufacturing conditions of compressed wood from OPTs and utilized them as raw materials for various purposes. In compressed OPT, wood is compressed in the transverse direction to prevent cell damage; otherwise, mechanical and physical properties are adversely affected (Kollman et al 1975).…”
