“…As can be seen from the Table, the changes at low irradiation dose are not significant but compressive strengths have decreased after 140.0 and 200.0 kGy irradiation doses owing to parallel and perpendicular directions, respectively. The effect of high energy radiation on wood has been investigated by different authors (9,10).…”

In this study, spruce samples were impregnated with acrylonitrile (AN), methyl methacrylate (MMA), allyl glycidyl ether (AGE), AGE/AN or AGE/MMA monomers and monomer mixtures. In situ polymerization (copolymerization) was achieved by gamma irradiation. The relationship between the mechanical properties of the wood-polymer(copo1ymer) composites and the kind and quantity of polymers and copolymers, irradiation dose and artificial aging treatment of the wood was investigated. The fine structure of wood-polymer(copo1ymer) composites was determined by Scanning Electron Microscopy. The presence of homopolymer and copolymers increased the mechanical properties of the wood. The compressive strength and Brinell Hardness Numbers, determined for untreated and treated wood samples, indicated that the mechanical strength of wood-polymer(copo1ymer) was significantly increased in the presence of P(AGE/MMA). At maximum percent conversion, the percentage increase in the compressive strength with regard to the applied force perpendicular to the fibers in spruce was 218%. After aging for 28 days, it was found that there were no significant changes in mechanical stability. PROCEDURES MaterialsThe following commercial reagents were purchased from Merck Methyl methacrylate (MMA) , acrylonitrile (AN), allyl glycidyl ether (AGE).
