Abstract
In this paper, an experimental study regarding the maximum bearing strengths of bolted-joint of glass epoxy composite laminate with [90/ + 45/ -45/0]s, [90/0/ + 45/ -45 ]s and [ +45/ -45/90/0]s stacking sequences is presented. The ratio of the distance from the hole center to the top edge to the hole diameter is four ( E/D = 4) , and the ratio of the specimen width to the pin diameter is five ( W/D = 5 ) . The results show that the bearing strength increase when the torque increase, but the trend is diminishing. When torque is 5N · m, strengths of three plies are found to be stronger when compared to pinned-joint by up to 175% , 196% , 141%. When it is pinned-joint,the strength of [90/ + 45/ -45/0]s increases by 12. 7% than [90/0/ +45/ -45]s, the strength of [ +45/-45/90/0]s increases by 10.8% than [ 90/ + 45/ - 45/0 ]s. But when torque is used by hand, the strength of [90/ +45/ -45/0]s increases by 3. 5% than [90/0/ +45/ -45]s,the strength of [ +45/ -45/90/0]s increases by 0. 37% than [90/ +45/ -45/0]s. As the rate of washer outer diameter to inner diameter increases from 2 to 3, the bearing strength increases, but it changes very little when it is from 3 to 4.关键词
