摘要
为了探索风力发电机叶片复合材料原材料炭化竹片及杉木薄板的环氧树脂浸渍性能,将炭化竹片及杉木薄板浸渍在不同固含量的混合环氧树脂中,研究炭化竹片及杉木薄板试件在不同浸渍时间的浸渍量。结果表明:(1)当环氧混合浸渍树脂的固含量相同时,随着浸渍时间的延长,杉木薄板和炭化竹片的树脂浸渍量逐渐增加,而后趋于稳定;(2)在相同的浸渍时间内,杉木薄板和炭化竹片在较高固含量的环氧混合浸渍树脂中的树脂浸渍量均高于低固含量的环氧混合浸渍树脂;(3)炭化竹片的树脂浸渍量均较杉木薄板低,说明材料的硬度或密度对树脂浸渍量有很大的影响。
In order to explore the epoxy resin impregnation property of the raw and semifinished materials of wind turbine blades composite materials-carbonized bamboo sheet and Cunninghamia lanceolata thin timber,the relationship between their resin impregnation increment and impregnation time was studied.They were impregnated in mix epoxy resins with different solid contents,and then to calculate the amounts of resin impregnation with different time durations.The results showed that:(1)When the solid contents of the mix epoxy resin were the same,the impregnation increment of the C.lanceolata thin timber and carbonized bamboo sheet increased with the impregnation time and then became stable;(2)When the impregnation time durations were the same,the impregnation increments of the C.lanceolata thin timber and carbonized bamboo sheet impregnated in mixed epoxy resin with higher solid contents were higher than those in mixed epoxy resin with lower solid contents;(3)The resin impregnation increment of the carbonized bamboo sheet was lower than that of C.lanceolata thin timber,indicating that hardness or density had significant effect on resin impregnation increment.
