How it’s Made: Fabricating a Composite Truck Cab

composite truck cabSince 1999, Daycab Company, in Rockwood, TN, has been using composites to retrofit class 8 commercial trucks with sleeper cabs to day cabs. Why would anyone be interested in having the sleeper cab removed, and a composite day cab installed you ask? Once a commercial truck gets to a certain age, many fleets will not run them and purchase new ones. The old trucks are then auctioned off, and are popular among local farmers, short haul companies and dealerships. The large abundance means they sell quite cheap.[divider_padding]

When first speaking with Zach Martin, Product Design Specialist and Machine Programmer at Daycab Company, I was surprised to hear that commercial trucks were quite desirable with the sleeper cabs removed. The reasons for this vary: farmers like non-sleeper cabs because loading in grain or other products at a station might have a height restriction that a sleeper can’t meet. Removing a sleeper also saves on weight, which could instead be used for carrying more cargo.

Short haul companies have the same issue as farmers with the weight of the sleeper and cargo, and because they work in more localized areas (farms, rock yards and landscaping companies), they require better visibility out the back.

Precision Board Plus HDU is used to manufacture the part used to fill the void created once the sleeper cab is removed. In this case, a Peterbilt semi truck is going to be converted. With the cab removed and the void exposed, Precision Board Plus HDU is machined using a 5-axis CNC router. This male mold is then coated with a sealer, vinyl ester, and is sanded. Red hard gelcoat and fiberglass is applied, to start the female mold. Plaster, fiberglass and resin complete the final stages.

Once the female mold is completed, gelcoat and fiberglass is shot to make the final production part. The part is completed by being trimmed on a CNC machine, and is then painted and installed on the Peterbilt truck, providing a great looking finished product.

Suffolk University – 3D Design with Precision Board

Suffolk University HDU DesignSuffolk-University-HDU-Design

Suffolk University Students Design with Precision Board HDU

Precision Board is a truly user-friendly medium for art and design. It allows even the most entry-level artists, architects, and designers to create a tangible object from just an idea and some rudimentary tools. Whether the objective is structural, architectural, or abstract, anyone can design with Precision Board! Creating with Precision Board doesn’t require woodcarving expertise, CAD programming experience, or any other special talents. It’s easy to work with, and all it takes is a little inspiration, as students from Suffolk University found out recently.

Professor Bebe Beard of the New England School of Art and Design at Suffolk University contacted us a few months ago with a unique project idea for her 3D Design class. She wanted to offer her students the opportunity to create something from scratch, coming up with the design and assembling the final product all on their own. The plan was for students to start with an intact block of foam, cut it into individual components, and then reassemble the pieces to create a new and distinctly different shape. This is a valuable exercise in spatial awareness and the architectural mindset, allowing students to put theory into practice in short order.

The students all started out with equal sized cubes of Precision Board, either PBLT-12 or PBLT-15. This density range is a good choice for design products like this, as our 12-20 PCF (pounds per cubic foot) Precision Board strikes a perfect balance between low weight and high durability. The students used a band saw to make six separate cuts through their Precision Board cube, ending up with seven individual pieces of HDU. If assembled together in the order they were cut, the pieces could be used to reform the cube. But the point of the project was to branch out and create something personal, so the students set to work. First, they sanded their cut pieces to create a smooth surface for painting and bonding. Using  Formula 560 canopy glue, the students bonded the HDU pieces together in a variety of unique patterns. The students painted their small statues with acrylic paint, either before or after they assembled the pieces together. Another aspect of the project was to examine the effects of lighting on their completed statue, and the students’ paint jobs really accentuate the different ways light falls across the structures.

Suffolk University HDU Design

As you can see, the assignment was a resounding success, and the students turned out some really impressive miniature display pieces. This project showcases how easy it is it design and create with Precision Board HDU foam, even without much prior experience in artistic design. We’d like to thank Bebe Beard for coming up with such a fresh and constructive way to use Precision Board. Be sure to check out her website to see some of the personal projects she’s worked on.

Laser Cutting Foam Precision Board: OSHA Approved, Highly Effective

Laser Cutting Foam Precision Board with Universal Laser Systems

For those with access to the necessary equipment, lasers can be an effective means of cutting, engraving, and marking various materials. High power, high-wavelength Carbon Dioxide lasers are widely used for material processing, namely for their versatility and relatively low cost as compared to solid-state laser systems. CO2 lasers are ideal for projects that require cuts or engravings so precise that they prevent the use of hand tools, or even a CNC router. But with such a volatile cutting technology, extra precautions need to be observed to ensure the safety of the laser operator. With this in mind, we set out to test the limits of our Precision Board Plus. Not only did we want to ensure that Precision Board could be effectively processed using a CO2 laser, we wanted to prove that it was completely safe to do so. So we turned to Universal Laser Systems to give us a hand with laser cutting foam HDU.

When any material is burned and vaporized, it gives off certain gaseous byproducts called effluent. Since CO2 lasers cut and engrave by literally burning through the material with focused beams of light, the laser operator is always in close proximity to the effluent, and usually in an enclosed space. If the released gasses have any harmful properties, this could pose a serious hazard to the operator’s safety. For our tests, we wanted to ensure that the effluent byproducts of Precision Board did not exceed OSHA’s Permissible Exposure Limits (PEL), federal regulations that dictate safe chemical exposure levels.

Size comparison of laser-cut Precision Board pieces

For the tests, we chose to use a selection of densities of Precision Board to achieve the most accurate results. To test the efficacy of cutting and engraving, we chose to use our lightest density, PBLT-4, and one of our most popular signage densities, PBLT-15. This would give us a good idea of the surface definition and cut precision we could achieve with Precision Board, as it will only improve with denser material. For the OSHA PEL test we chose our heaviest material, PBHT-75. Because of the high density, it would release the maximum amount of effluent when laser processed. If the PBHT-75 passed the PEL test, we knew that every lighter density would pass as well, since every density of Precision Board is identical in chemical composition. Universal Laser Systems used their PLS6.150D CO2 laser system for every test in conjunction with air assist, a honeycomb cutting table, and dual-laser configuration.

I won’t leave you in suspense: Precision Board passed every test with flying colors. For the OSHA PEL test on PBHT-75, Universal Laser Systems used a sophisticated RTGA Mass Spectrometer and a carbon monoxide detector to monitor the levels of effluent at all times during testing. They noted the following in their report: “The concentration of the detected compounds did not exceed their respective OSHA PEL at any level of filtration during this study.” It’s official, and we have the lab report to back it up: Laser cutting foam Precision Board is completely safe.

As for the cutting and engraving tests, you can see for yourself how they turned out. The level of detail achieved on every sample is simply incredible. Even the ultra-lightweight PBLT-4 can be engraved to a high degree of precision and surface detail. PBLT-15 and PBHT-75 performed even better, and their higher densities will allow for greater durability over a longer period. The word is finally in: Precision Board is perfect for laser cutting and engraving, so get out there and laser it up! Laser cutting foam HDU is a great processing method, so click here for a free sample and start laser cutting Precision Board today.
