| Abstract: | Reasons for the aging of wood residues composite were discussed and analyzed,which were the aging of wood residues,the aging of adhesive,and the rebounding and expansion contraction stress.And then,testing measures of the accelerated aging of wood residues composite was introduced pointing out that ASTM D1037 6-cycle accelerated aging method and aging instrument detection method would be used.Influencing factors of aging of wood residues composite were temperature,humidity,sample size,etc. |
