Analyzing Carbon Fiber Filament Damage

Posted by Maureen Redmond on Jan 8, 2021 8:37:27 AM


The handling and guiding methods of carbon fibers
to prevent filament damage is often overlooked. However, it is an extremely important factor in carbon fiber production and downstream processes using carbon fiber.

Redirection with sharp angles, use of guides without proper surface finish, excessive tension, static contact points: these are all factors that can induce damage to the filaments in the carbon fiber tow. Broken filaments not only degrade the strength of the carbon fiber, but also cause issues in processing leading to production downtime.

Broken filaments accumulate on rotating parts and will snowball into a mess quickly, which not only needs an operator to intervene but can stop production or create defects in the product.

The main reason proper assessments are not made for fiber damage caused by inadequate handling is that there have been no quantitative means to measure fiber damage. Read more to find out about tools to accomplish this and some analyzation studies.

Dispensing with 6-Axis Robots

Posted by Maureen Redmond on Jan 7, 2021 2:04:36 PM

Dispensing by means of 6-axis robots is an efficient platform for various dispensing applications, when a 3-axis tabletop robot does not provide the flexibility required.

Software options are available to allow for path following of  3D CAD models or sketch patterns within a 3D model. Product models can be inserted into a simulated robot environment so that dispensing simulations can be generated offline. This enables the programmer to verify any axis limitations or collisions without taking the actual robot offline and prevents downtime of production.

Dispense verification options are also available to ensure proper dispense bead width tolerances are met, alert upon dispense failure, or for traceability requirements. Bead reconstruction or repair can be done on the spot to prevent product waste and down time.

Download a brochure for further details and options available.

Read the below to see which dispenser to equip on the 6-axis robot for certain applications.

Karakuri (からくり) Automation Systems

Posted by Maureen Redmond on Nov 30, 2020 2:42:44 PM

Karakuri ningyo (からくり人形) are traditional Japanese automated puppets with origins dating back to the 7th century. Eventually, they gained widespread popularity around 17th century Edo period in Japan, when a theater opened in Osaka with Karakuri puppets on stage. These dolls relied solely on mechanical components such as springs or cams and clever engineering techniques to produce life-like movements, such as a tea serving doll or an archer doll which loads an arrow in his bow and shoots them one by one. Fast forward to present day 2020, and we live in an age where programmable logic controllers enable precise control sequences in millisecond increments, and 6-axis robots configure a completely automated production line. We now integrate sophisticated electronic controls to fulfill our industrial automation requirements.

However, there are still industrial automation processes that can be done by a fully mechanical, “Karakuri” type system. These systems would require no electricity, which could help achieve a green manufacturing target that may be required in a plant. Having no electronic controls also means lower cost, making integration of this type of automation affordable in situations where cost is a key

Winders for Carbon Fiber and High-Performance Fibers

Posted by Maureen Redmond on Oct 27, 2020 9:42:12 AM

Winding fibers to produce bobbins or fiber packages is a necessary evil in many composite production processes. Winding is an intermediate step and does not contribute to the production of the final product. If possible, it would be preferred not to wind, and instead take the fibers directly to the final product.

However, composite manufacturing processes come in all shapes, speeds, and sizes, so integrating the composite manufacturing process with the actual fiber production process is impossible. Therefore, we are left with the task of winding the fiber to an easy to handle form to take it to the next process.

When winding carbon fibers in particular, there are three main objectives:

1 – Good build shape of package

2 – No twist in the fiber

3 – Minimal damage of the filaments

The means of achieving these properties vary depending on the type of fiber, number of filaments in the tow, sizing type/content and various other factors. This may require actual test winding, but typically we can assist you based on our decades of experience as well. Optimum winding parameters such as tension or wind ratios are difficult to determine without experience and our team of engineers can help you achieve the winding characteristic desired.

In this article, we would like to go over the different types of winders available and what applications they are the most fit for.

Benefits of Non-Contact Jet Dispensers

Posted by Maureen Redmond on Oct 20, 2020 11:12:30 AM

A relatively new development in the world of fluid dispensers, the non-contact jet dispenser uses a jetting mechanism to drop fluids from a distance on to the substrate, so that the nozzle never touches the surface of the product. Jet dispensing is performed by high speed dot pulsations from the nozzle, therefore dot dispensing as well as connecting these dots to form line dispensing can be achieved.

These jetting solutions are developed by Musashi Engineering. Though relatively new in the U.S. market, Musashi Engineering is a global leader in fluid dispensing systems for industrial automation, and their product developers have fine-tuned their dispensers to provide the highest accuracy and lowest product rejection rates possible.


See some applications of the jet dispenser in this video. 

The guide below goes over some of the unique benefits the jetting systems can bring to the table, and also the various jet dispenser models available.

The Importance of Monitoring the Tension of Fibers

Posted by Maureen Redmond on Sep 28, 2020 3:14:04 PM

In upstream composites production processes, it is often necessary to control a fiber 

or a band of fibers to an optimum tension value. However, identifying the correct tension is often overlooked, and production processes still utilize tensioning systems which were developed decades ago without much consideration.

If the starting tension at the creel is not controlled properly, then the final product may be constructed of fibers with varying tension. As a result, it will not fully utilize the strength of all fibers equally. This can degrade the mechanical properties of the final product.
