Abstract

Particleboards were fabricated using Rhizophora spp. wood particles as phantom material in for photon beams with a target density of 1.0 g/cm3. Two types of tannin, namely the extracted tannin and the commercialized tannic acid were added into the particleboard to improve the physical strength of the particleboards. The strength of the particleboards was measured according to Japanese Industrial Standards (JIS A-5908:2003). The microstructure of the particleboards was investigated using a Scanning Electron Microscope (SEM) coupled with an Energy Dispersive X-ray Analysis (EDXA) to determine the elemental composition of the particleboards. The mass attenuation coefficient of Rhizophora spp. particleboards were measured by using the attenuation of x-ray fluorescent (XRF) photons from niobium, molybdenum, palladium, silver and tin metal plates that provided photon energies between 16.59 and 25.26 keV. The CT images of the particleboards were obtained to determine the CT number and mass attenuation coefficient at 80, 120 and 140 kVp x-ray energies. The results showed that tannic acid provided better improvement of physical strength of the particleboard based on the internal bond strength, thickness swelling and water absorption tests. The mass attenuation coefficient of tannic acid-Rhizophora spp. particleboards were found to be the nearest to calculated XCOM of water indicated by the χ2 values. The CT study showed that tannic acid-Rhizophora spp. particleboards have the nearest CT numbers to water substitute at all CT energies.
