ジャーナル フリーFour kinds of FRP panels with three layers consisting of roving glass cloth and/or glass mat reinforced unsaturated polyester resin were acoustically excited and tested by using the acoustic fatigue testing facility. The shape of each test panel is rectangular and identified with one bay of the aircraft body. In the experiments, it is observed that the lamination structure of the test panel may characterize the failure pattern and the glass mat reinforced test panel may be more isotropic than the roving glass cloth reinforced test panel. The experimental results indicate that the acoustic fatigue strength of FRP test panel is considerably lower than the fatigue strength of FRP materials tested under constant stress. In order to predict the acoustic fatigue life of test panels, it is assumed that the acoustic load used here is a random noise with narrow frequency band-width and the modified Miner's rule is applicable to FRP materials . Under these assumptions, the acoustic fatigue life of test panels is predicted by the experimental data of fatigue strength of FRP obtained from constant stress testing and has the good agreement with their experimental data.抄録全体を表示PDF形式でダウンロード (6440K) -

ジャーナル フリーAs shown in the previous paper, a linear analysis of the strain distributions in filamentwound pressure vessels by use of the finite element method can explain the experimental results in the initial stage of pressure loading. However, it was found that the experimental pressure versus strain curves on some dome portions became nonlinear with an increase of internal pressure and it seemed to result from the variation of dome configuration. Accordingly, in the present paper, the stress and strain analyses in filament-wound pressure vessels are treated as an geometrically large deflection problem by using the modified load incremental method. And it is shown that the numerical results for a rocket moter case (EXOS-KM-B) which is to be launched by Inst, of Space & Aeronaut. Sci., Univ. of Tokyo, agree fairly with the experimental results.抄録全体を表示PDF形式でダウンロード (3458K) -
