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
本文给出了碳纤维复合材料板和壳试验件制作工艺方案；在进行了模具的设计与制作、树脂选取后，采用二维编织技术，利用rtm工艺完成了试验件的制作。
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
由试验可见，在单层试验板中没有排水层或排水层不通畅时，较低的水压就能在防水膜后形成渗流通路；在双层试验板中没有排水层或排水层不通畅时，防水膜能抵抗一定程度的渗漏水压；只有在双层试验板中的排水层畅通时，防水膜才能有效地将渗漏水控制在排水层中排走。
