进行了33个木材与玄武岩纤维布(BFRP)粘结试件的单剪试验,主要考察粘贴层数对BFRP与木材粘结性能的影响,测量了不同粘贴层数下BFRP与木材界面的应变分布规律。比较了在不同粘贴层数下BFRP与木材之间的极限荷载和粘结应力分布情况,结果表明,随着BFRP粘贴层数的增加,有效粘结长度呈增加趋势,在木材含水率为10%条件下,1,2,3层玄武岩纤维布与木材(福杉)的有效粘结长度分别在100,120,150mm左右;粘贴层数对木材与玄武岩纤维布的极限粘结荷载也有一定影响,随BFRP粘贴层数的增加,极限粘结荷载逐渐增加。
A single shear test was carried out on 33 bonded specimens of wood and basalt fiber cloth (BFRP). The effects of the number of layers on BFRP and wood bonding properties were investigated. The strain distributions of BFRP and wood at different bonding layers were measured law. The ultimate load and bond stress distribution between BFRP and wood were compared under different adhesive layers. The results showed that the effective bond length increased with the increase of the number of BFRP layers. When the wood moisture content was 10% Under the conditions of 1,2,3 layers of basalt fiber cloth and wood (Fuso) the effective bonding length of 100,120,150 mm or so; adhesive layer on the wood and basalt fiber cloth ultimate bonding load also have an impact, with the BFRP paste As the number of layers increases, the ultimate bond load gradually increases.
