Effects of pressing cycles and durations on the properties of compreg oil palm wood
Oil palm wood (OPW) extracted from the oil palm trunks and subjected to a four-step compreg method consisted of drying, impregnation, re-drying and hot-pressing densification process. For the densification process, four different pressing cycles (involving 1–3 cycles) were proposed and conducted wit...
