    適用范圍

    4.1 The COPVs covered in this guide consist of a metallic liner overwrapped with high-strength fibers embedded in polymeric matrix resin (typically a thermoset). Metallic liners may be spun formed from a deep drawn/extruded monolithic blank or may be fabricated by welding formed components. Designers often seek to minimize the liner thickness in the interest of weight reduction. COPV liner materials used can be aluminum alloys, titanium alloys, nickel-chromium alloys, and stainless steels, impermeable polymer liner such as high density polyethylene, or integrated composite materials. Fiber materials can be carbon, aramid, glass, PBO, metals, or hybrids (two or more types of fiber). Matrix resins include epoxies, cyanate esters, polyurethanes, phenolic resins, polyimides (including bismaleimides), polyamides and other high performance polymers. Common bond line adhesives are; FM-73, urethane, West 105, Epon 862 with thicknesses ranging from 0.13 mm (0.005 in.) to 0.38 mm (0.015 in.). Metal liner and composite overwrap materials requirements are found in ANSI/AIAA S-080 and ANSI/AIAA S-081, respectively. Pictures of representative COPVs are shown in E07’s forthcoming Guide for Nondestructive Testing of Composite Overwraps in Filament-Wound Pressure Vessels Used in Aerospace Applications.

    4.2 The operative failure modes COPV metal liners and metal PVs, in approximate order of likelihood, are: (a) fatigue cracking, (b) buckling, (c) corrosion, (d) environmental cracking, and (e) overload.

    Note 2: For launch vehicles and satellites, the strong drive to reduce weight has pushed designers to adopt COPVs with thinner metal liners. Unfortunately, this configuration is more susceptible to liner buckling. So, as a precursor to liner fatigue, attention should be paid to liner buckling.

    4.3 Per MIL-HDBK-340, the primary intended function of COPVs as discussed in this guide will be to store pressurized gases and fluids where one or more of the following apply:

    4.3.1 Contains stored energy of 19 310 J (14 240 ft-lbf) or greater based on adiabatic expansion of a perfect gas.

    4.3.2 Contains a gas or liquid that would endanger personnel or equipment or create a mishap (accident) if released.

    4.3.3 Experiences a design limit pressure greater than 690 kPa (100 psi).

    4.4 Per NASA-STD-(I)-5019, COPVs shall comply with the latest revision of ANSI/AIAA Standard S-081. The following requirements also apply when implementing S-081:

    4.4.1 Maximum Design Pressure (MDP) shall be substituted for all references to Maximum Expected Operating Pressure (MEOP) in S-08......

    無損檢測檢測形式

    如對金屬材料,可檢測厚度為1~2mm薄壁管材和板材,也可檢測幾米鋼鍛件;而且缺陷定位較準確,對面積型缺陷檢出率較高;靈敏度高,可檢測試件內部尺寸很小缺陷;并且檢測成本低、速度快,設備輕便,對人體及環境無害,現場使用較方便。  但其對具有復雜形狀或不規則外形試件進行超聲檢測有困難;并且缺陷位置、取向和形狀以及材質和晶粒度都對檢測結果有一定影響,檢測結果也無直接見證記錄。  ...

    例如飛機機翼,采用兩次曝光和實時檢測方法都能檢測出脫粘、失穩等缺陷。膠結結構檢測以硼或碳高強度纖維本身粘接以及粘接到其他金屬基片上復合材料檢測、藥柱質量檢測以及印制電路板焊點檢測等。然而這種檢驗方法由于設備昂貴、需要沖洗顯影、對環境振動敏感和需要對被測加載,因此限制了推廣能力,目前主要在實驗室使用。...
