Physical and mechanical properties of composite boards based on wood fiber/oil palm kernel shell with different polyurethane composition

In Malaysia, the oil palm industry has brought significant impacts to the economy, social, geographical as well as the environment but the waste produced from palm oil production has become concerned. Palm kernel shell is an abundant residue produced from the oil palm processing. The possibility...

Palm kernel shell is an abundant residue produced from the oil palm processing. The possibility of utilizing palm kernel shell in the fiberboard could help to overcome the shortage of wood resources facing in the wood based industry. Therefore, a series of fiberboard samples have been fabricated using wood fiber/palm kernel shell at ratio of 100/0, 85/15, 75/25, and 65/35.
