一、引言压力容器(含发动机壳体)中,纤维强度的转化率其表示式如下:纤维强度转化率肠~容器中环向纤维发挥强度纤维复丝拉伸强度X 100务纤维束经过预浸胶、固化、制样、选样后制得的复丝,进行拉伸测试,其强度已有较大损失,这是难免的。问题在于绕制复合材料压力容器时,各种纤维强度又有进一步的损伤递降,但各种纤维强度损失程度是不一致的。据报导,国际上经过十几年的实践证明:(1)在纤维缠绕成型的高压容器中(含发动机壳体),在相同的结构尺寸,
I. INTRODUCTION The conversion rate of fiber strength in a pressure vessel (including the engine housing) is expressed as follows: Fiber strength conversion rate Intestinal fiber in the gut exerts strength in the container Tensile strength of the multifilament X 100 Fiber bundles are pre-dipped , Curing, sample preparation, after the sample prepared multifilament, tensile test, the strength has been a greater loss, it is inevitable. The problem is that when wound around a composite pressure vessel, there is a further decrease in the damage of various fiber strengths, but the degree of loss of various fiber strengths is inconsistent. It is reported that after more than ten years of practice in the world, it has been proved that: (1) in the high-pressured fiber-wound vessel (including the engine casing), in the same structure size,
