Shell test pressure
殼體試驗壓力
The second example is to study the problem of shape control for the composite plate structure . finally , the plate and shell test pieces are designed and manufactured using rtm . they all are expected as the base of the research on adaptive blade with piezoelectric actuators
本文給出了碳纖維復(fù)合材料板和殼試驗件制作工藝方案；在進(jìn)行了模具的設(shè)計與制作、樹脂選取后，采用二維編織技術(shù)，利用rtm工藝完成了試驗件的制作。
The phenomena can be observed in the tests low seepage pressures can easily form passageways behind the waterproof layer if there is no drainage layer or the drainage layer is blocked in the single - shell test slab ; the waterproof layer can resist higher seepage pressure if there is no drainage layer or the drainage layer is blocked in the double - shell test slab ; the seepage water can be controlled and drained away in the drainage layer by the water proof layer only if there is unblocked drainage layer behind it in the double - shell test slab
由試驗可見，在單層試驗板中沒有排水層或排水層不通暢時，較低的水壓就能在防水膜后形成滲流通路；在雙層試驗板中沒有排水層或排水層不通暢時，防水膜能抵抗一定程度的滲漏水壓；只有在雙層試驗板中的排水層暢通時，防水膜才能有效地將滲漏水控制在排水層中排走。
