摘要： A process and equipment for making seamless composite tubes. Composite material is applied on a mandrel (12) which includes an inflatable bladder (36) and inserted in a single piece mold (14). The bladder is pressurized for pressing the composite material against the mold wall for molding and curing thereof. In order to prevent seizing of the tube by the mold and thus allow easy removal of the cured tube, the mold is composed of a composite of resin impregnated carbon fiber material wherein the carbon fiber material has a negative coefficient of thermal expansion along the length thereof and is oriented at an angle of between 15 and 40 degrees relative to a radial plane of the mold. In order to eliminate the use of inefficient and inconvenient cure ovens, a heat generating element (144) may be disposed internally of the mandrel for curing of the composite material.
摘要翻译：制造无缝复合管的工艺和设备。将复合材料施加在包括可膨胀囊（36）并插入单件模具（14）中的心轴（12）上。加压气囊以将复合材料压靠在模具壁上以进行模制和固化。为了防止管子被模具卡住，从而容易地除去固化管，该模具由树脂浸渍碳纤维材料的复合材料构成，其中碳纤维材料沿其长度具有负的热膨胀系数并且相对于模具的径向平面以15至40度的角度定向。为了消除使用低效和不方便的固化炉，发热元件（144）可设置在心轴的内部以固化复合材料。
