Carbon Fiber Industrial Equipment碳纤维工业设备
As many industries shift from using aluminum or steel in many products to carbon fiber or other composite materials, they’re experiencing higher performance with less weight. For example, we created a carbon fiber lance that extended a paint tube up to 27′ and was over 70% lighter than an equivalent stiffness steel tube.Steel tubing proved too heavy for this application, but carbon fiber tubing got the job done without sacrificing any performance.
随着许多行业从在许多产品中使用铝或钢转向碳纤维或其他复合材料，他们正在体验到更高的性能和更轻的重量。例如，我们创造了一种碳纤维喷枪，可将油漆管延长至 27 英尺，并且比同等刚度钢管轻 70% 以上。 事实证明，钢管对于这种应用来说太重了，但碳纤维管在不牺牲任何性能的情况下完成了工作。

Roll Wrapping卷管
Roll wrapping is an excellent process to produce high quality carbon fiber tubing and fiberglass tubing.The roll wrapping process utilizes pre-impregnated (prepreg) carbon fiber or fiberglass materials.The prepreg is cut into patterns with specific fiber orientations.The patterns are rolled onto a mandrel and then wrapped with a thin plastic film.The plastic film applies pressure and contains the resin during the curing cycle.After the part has cured, the mandrel is extracted and the plastic film is removed.
卷绕是生产高质量碳纤维管和玻璃纤维管的绝佳工艺。 卷筒包装工艺采用预浸渍（预浸料）碳纤维或玻璃纤维材料。 预浸料被切割成具有特定纤维取向的图案。 将图案卷到心轴上，然后用薄塑料薄膜包裹。 塑料薄膜在固化周期中施加压力并包含树脂。 零件固化后，取出心轴并去除塑料薄膜。
Advantages of Roll Wrapping
卷绕的优点
Maximum Strength and Stiffness – the use of prepreg materials and the ability to precisely control fiber orientation results in maximizing the performance of carbon fiber and fiberglass products
最大强度和刚度 – 预浸料的使用和精确控制纤维取向的能力可最大限度地提高碳纤维和玻璃纤维产品的性能
Customization – prepreg plies can readily be added or subracted allowing the tube to be customized with different wall thicknesses
定制 – 预浸料层可以很容易地添加或分装，允许使用不同的壁厚定制管材
No Minimum Quantities – Because each tube is made one at a time, small production runs are available.
无最小数量限制 – 由于每根管子一次生产一根，因此可以进行小批量生产。

Various exterior finish options are available on all carbon fiber products. Typical options are:
所有碳纤维产品均提供各种外部饰面选项。典型的选项包括：
1. Standard Finish – “Cello-wrap” 1. 标准表面处理 – “大提琴包装”
Cello-wrap is slang for describing the textured exterior of carbon fiber tubes made using the roll wrapping process.As shown in the photo to the right, the surface of the carbon fiber tube is slightly textured with small resin ridges, about 0.001″ thick.
大提琴包装是俚语，用于描述使用卷绕工艺制成的碳纤维管的纹理外观。 如右图所示，碳纤维管的表面略有纹理，有小树脂脊，厚度约0.001英寸。
2. Sanded Finish2. 打磨处理
Smooth exterior finish with a matte-like exterior where the tubes are the color of graphite (greyish).This is seen in the two tubes on the left side of the picture (the three tubes on the right have cello-wrap finish)
光滑的外部饰面，具有哑光般的外观，其中管子是石墨的颜色（灰色）。 这在图片左侧的两个管子中可以看到（右侧的三个管子有大提琴包装饰面）
3. Ground Finish3. 地面处理
Ground finish refers to centerless grinding the carbon fiber tubes to a precise OD tolerance.The carbon fiber tubing has the same matte-like finish as sanded, but with an added advantage of tighter OD tolerances.
研磨光洁度是指将碳纤维管无心研磨至精确的外径公差。 碳纤维管具有与打磨相同的哑光光面，但具有更严格的外径公差的额外优势。
4. Clearcoat Finish4. 清漆饰面
The clearcoat finish is generally a glossy exterior that brings out the carbon fiber “look” of the carbon fiber tubes.The clearcoat also provides UV resistance to sunlight exposure.The picture to the rightshows the difference between a cello-wrap and clearcoated carbon fiber tube with the 2×2 twill carbon fabric.
清漆饰面通常是有光泽的外观，带出碳纤维管的碳纤维“外观”。 清漆还具有抗紫外线能力，可抵抗阳光照射。 右图显示了大提琴包裹和透明涂层碳纤维管与2×2斜纹碳纤维织物之间的区别。
5. Painted Finish5. 涂漆饰面
A painted exterior in various colors is possible.Although this is not a popular choice for most of our customers, it is common for carbon fiber fishing rods, golf shafts and softball bats.
可以涂上各种颜色的油漆外观。 虽然这对我们大多数客户来说不是一个受欢迎的选择，但它在碳纤维钓鱼竿、高尔夫球杆和垒球棒中很常见。

Galvanic Corrosion: Is galvanic corrosion a concern when bonding carbon fiber to metals? 电偶腐蚀：将碳纤维粘合到金属时，电偶腐蚀是否是一个问题？
Yes, carbon fiber is electrically conductive. Corrosion occurs by an electrochemical process where metal corrodes due to electrical contact, in the presence of an electrolyte. This can be prevented by insulating the tube with fiberglass (non-conductive). Often times, anodized aluminum and/or the epoxy layer can insulate enough to prevent galvanic corrosion. |
是的，碳纤维是导电的。腐蚀发生在电化学过程中，其中金属在电解质存在下由于电接触而腐蚀。这可以通过用玻璃纤维（不导电）绝缘管来防止。通常，阳极氧化铝和/或环氧树脂层可以绝缘到足以防止电偶腐蚀。 |
Low CTE: What is the CTE of your carbon fiber tubes?低热膨胀系数：你们碳纤维管的热膨胀系数是多少？
Carbon fiber laminates have low CTE compared to standard metals. Laminate design can be modified to make zero/specific CTE’s. Reach out to our sales team for additional information. 与标准金属相比，碳纤维层压板的热膨胀系数较低。可以修改层压板设计以制作零/特定的 CTE。请联系我们的销售团队以获取更多信息。

Can be done with tape, dowel, plug, or clamped to a sacrificial material 是的，加工碳纤维管相对简单。有关有用的提示，请参阅下文。-钻头：用于复合材料的整体硬质合金铣刀头，金刚石（如果有） – 主轴速度：越快越好 -进给：基于厚度（专有） -加固背面以防止爆裂。可以使用胶带、销钉、插头或夹在牺牲材料上完成

Standard Tolerances: What are your standard tube tolerances?标准公差：你们的标准管公差是多少？
Temperature (Tg): What temperature can your tubing withstand?温度 （Tg）：您的管道可以承受什么温度？
Our standard, high, and ultra-high modulus tubes are made with standard 250° F cure epoxy pre-preg. We have not verified the Tg, but theoretical Tg is estimated at ~250° F. 我们的标准、高模量和超高模量管采用标准的 250° F 固化环氧树脂预浸料制成。我们尚未验证Tg，但理论Tg估计为~250°F。
Temperature (Tg): Is high temp material available?温度（Tg）：是否有高温材料？
We offer 350° cure, standard modulus, material as a custom solution. Higher temp material can be acquired but is on a per-part basis. Reach out to our sales team for additional information. 我们提供350°固化，标准模量，材料作为定制解决方案。可以获取更高温度的材料，但要按零件购买。请联系我们的销售团队以获取更多信息。
Twill vs. UD: What is the difference between the twill carbon fiber tubes and the UD carbon fiber tubes?斜纹布与UD：斜纹碳纤维管和UD碳纤维管有什么区别？
The simple answer – just the exterior ply of material. Unless noted on a specific product, all of our carbon fiber tubing is made with UD prepreg on the inside, and then will have either the UD exterior ply or a fabric ply. The twill carbon fiber fabric exterior is a popular choice as it provides the carbon fiber “look” that so many customers associate with carbon fiber. 简单的答案 - 只是材料的外部层。除非在特定产品上注明，否则我们所有的碳纤维管都是在内部使用UD预浸料制成的，然后具有UD外部层或织物层。斜纹碳纤维织物外观是一个受欢迎的选择，因为它提供了许多客户与碳纤维相关的碳纤维“外观”。
Twill vs. UD: Are the twill carbon fiber tubes stronger or stiffer than the UD carbon fiber tubes?斜纹布与UD：斜纹碳纤维管比UD碳纤维管更坚固还是更硬？
Yes and no. It depends on the wall thickness and which property is of interest. If the tube wall thickness is the same, technical speaking, the UD exterior tubes will be slightly stronger and stiffer in bending (less than 10%). However, the hoop strength of the fabric exterior tubes will be slightly stronger. Again, this strength or stiffness increase is only a small percentage and will not be noticeable without precise testing equipment. It is advised customers choose between these options based on cosmetics, not strength. Another consideration is if holes are to be drilled into the tube, the twill exterior will resist splintering better than the UD exterior.
是和不是。这取决于壁厚和感兴趣的属性。如果管壁厚度相同，从技术上讲，UD外管在弯曲时会稍微强一些，更硬（小于10%）。但是，织物外管的环向强度会略强。同样，这种强度或刚度增加只是很小的百分比，如果没有精确的测试设备，就不会很明显。建议客户根据化妆品而不是强度在这些选项之间进行选择。另一个考虑因素是，如果要在管子上钻孔，斜纹布外部将比UD外部更好地抵抗碎裂。
ROHS Compliance: Are your parts ROHS compliant?符合 ROHS 标准：您的零件是否符合 ROHS 标准？
Our standard carbon fiber prepreg is Considered ROHS compliant. A formal document can be sent upon request. 我们的标准碳纤维预浸料被认为符合ROHS标准。可应要求发送正式文件。
