Q1: How much thicker does a compression molded composite part have to be versus a metal part to achieve same stiffness? A1: The answer depends upon how the metal part is loaded. Is the part subjected to bending, tension, or compression loads? …
Q2: How much does tooling cost? A2: ... A rule-of-thumb for sufficient tooling return on investment is that the tool’s cost will be covered with 1000 production units...
Q3: Why does billet stock not truly replicate the 3D behavior of a compression molded part? A3: ... The BMC layer in the compression molding tool is a near quasi-isotropic fiber dominated lay-up in the plane of the plate, but resin dominated through the thickness. Therefore, if the machined part has a feature that needs strength in the direction out of plane, this cannot be attained…
Q4: How does one learn if compression molded parts are viable? A4: The best place to start is to request a copy of the TenCate Compression Molding Design Guide, from our online resource center at www.tencatecomposites.com/guides.
Q5: How do I structurally analyze a discontinuous fiber compression molded part? A5: ... With fiber orientation assumptions, an orthotropic FEA model can be created.
TenCate Cetex® thermoplastic chopped tape is an ideal high-volume, cost-effective solution for diverse industrial applications, from under foot to under carriages. Thermoplastic parts can be designed with PP, PET, or PA6 chopped carbon or glass fibers and allow for:
> Tapered edges
> Variable thicknesses
> Variable rigidity
> Integral ribs and surface textures
Thermoplastic’s design freedom provides improved strength over normal injection-molded plastics while still allowing injection overmolding of fine details, such as clips or secondary features.
Thermoplastic composite parts can be fine-tuned for optimized mechanical properties and kitted for high volume production of hundreds per hour. Parts and tools can be designed with minimal flashing to minimize waste and to provide efficient post-processing to final form.

ORIBI Manufacturing is a unique company specializing in thermoplastic composite fabrication for industrial applications. Matt Christensen, Chief Commercial Officer from ORIBI Manufacturing provides some insight on the trends and opportunities. Through the utilization of highly automated assembly, uni-directional Continuous Fiber Reinforced ThermoPlastic (CFR-TP) materials are leveraged, delivering highly scalable, predictable, and tight tolerance advanced composite parts.
Abstract: Q3: On processing, describe the general process and maybe the fast cycle times thermoplastics offer. How different or alike are the processes from metal stamp forming? A3: The process is most like stamp metal forming, but instead of using sheet metal, we essentially use blanks of uni-directional CFR-TPs. Our process does require a matched-metal two-piece tooling system which we develop and build in-house. Tooling costs vary by size and complexity of the part, but we have a lifetime guarantee on the tool so if a customer wears one out through manufacturing, we will make a replacement at no extra cost. We have some tools that have over 200,000 parts made and are still functioning very well.
Composites World interviewed key members of TenCate Advanced Composites’ Technology group for a recent blog post. In it they discussed thermoplastic tapes and the advancement of processing techniques such as in-situ consolidation. Here is a look at what we shared regarding which polymers and processing technologies we feel offer the best potential.
Abstract: Low Melt PAEK is a potential alternative to PEKK and PEEK in the quest for faster processing. Dr. Hans Luinge, director of Thermoplastic Composites Research and Product Development, recapped the difference in melt temperatures:
> TenCate Cetex® TC1225 Carbon fiber (CF)/LM PAEK tape 305°C (581°F)
> TenCate Cetex® TC1320 CF/PEKK tape 340°C (644°F)
> TenCate Cetex® TC1200 CF/PEEK tape 350°C (662°F)
“Cetex TC1225 LM PAEK was introduced in the TAPAS1 development program,” Luinge says. He shared how Airbus Nantes exhibited a fuselage panel with integrated stiffeners at the 2013 Paris Air Show. It was fabricated using the [TenCate Cetex® TC1225/Carbon] PAEK tape. Press-formed omega and butt-jointed T stringer elements made with automated fiber placement (AFP) were welded to the skin.
“Low-melt PAEK works well in AFP, stamp forming, and welding,” says TenCate Global Chief Technology Officer Scott Unger. He explained TC1225 LM PAEK holds promise for in-situ consolidation. There are two key factors to consider when choosing a product: tape quality and how well the matrix resin and fiber are distributed in the UD tape.
“Our tape is extremely consistent with 0 to 0.5% voids maximum,” says TenCate Director of Expert Services EU Winand Kok. “Our tape thickness is also very consistent, which is why we can achieve very accurate ply thicknesses in consolidated laminates. This consistency is also important for thermoplastic welding processes and in-situ consolidation.”
Unveiled by Elon Musk in 2013, the Hyperloop concept is a futuristic high-speed ground transport and transit system, with vehicles/pods traveling in a system of near-vacuum tubes at speeds over 1000 km/h (800 mph). The Hyperloop Competition III last month at SpaceX’s Hawthorne facility demonstrated speed feasibility. Competing with student teams from across the world, Delft Hyperloop’s Atlas 01 pod won second place, coming in under the winner’s speed top speed of 467 km/h (290 mph).
Delft Hyperloop’s pod launcher design features a full composite 2350 x 300 mm chassis weighing only 15 kg, and carbon fiber battery case. The pod’s launcher was manufactured with TenCate's 8020 epoxy-based carbon fiber woven and uni-directional prepregs, donated by TenCate Advanced Composites’ European Centre of Excellence for Thermoset Systems, based in Langley Mill (Nottingham, UK).
Backing structures can be used to increase strength and stiffness on composite mold tools.
Key considerations when designing tooling backing structures include:
These considerations offer the best opportunity to match the physical properties of the mold and utilize standard products readily available to our customers, such as TenCate AmberTool HX42.
A popular method for stiffening mold tools is the “Egg Crate” technique, where a cellular support structure is created with panels using materials similar to those used in the mold tool construction. Typical example: Carbon/epoxy prepreg mold panels could be made from monolithic carbon/epoxy prepreg laminates or sandwich panels utilizing carbon/epoxy skins.
TenCate Advanced Composites’ Tooling Academy took place at our Morgan Hill, California, USA, facility on June 12 and 13. Twenty graduates representing six customers and several of our summer interns participated.
The class featured an upgraded curriculum focused on the products and practices required for TenCate AmberTool® HX42 composite tool creation. It also included new tool sets with more complex features, allowing students to learn about many issues they will encounter in their composite tooling builds.
The academy included a full facility tour and evaluation of the three tools made during the course. In the end, the team that took the longest to complete the build produced the highest quality tool. All graduates received certificates of completion, a binder of all the presentation materials, and the TenCate AmberTool® Processing Guide. Many attendees can use this course for CPE credits.
We’d like to thank our participants and instructors FortORDWorks President Joe Johnson, Abaris Training Instructor Lou Dorworth, and TenCate Expert Services team member Jimmy Shedden. The next Tooling Academy will be held either Fall 2018 or Spring 2019 (depending on demand).
