Boeing will soon be generating enormous amounts of carbon fiber scrap and is looking for a way to use it. According to a fascinating story reported by Plastics Today, about two-thirds of the carbon fiber purchased by Boeing as an aircraft construction material ends up as waste. It wasn’t clear why the percentage is so high. Presumably, the ratio will decline as Boeing and its partners gain more experience using the material. Much of the body of the Dreamliner 787 is made from carbon composites.
The commercial launch of the Dreamliner has been delayed about two years, but testing results are increasingly positive and full-scale production will require huge amounts of carbon fiber. The aircraft was originally expected to become commercial in May 2008, but the best hope now is for the planes to enter service by the end of this year. Boeing hopes to expand production to 10 per month in 2013. Another source of older carbon fiber will be parts from other planes that are being retired.
According to the report by Tony Deligio, Boeing is working with compounder RTP to qualify compounds using the recovered carbon fiber. An RTP Company glass fiber-reinforced PEEK compound is already specified for the hinge bracket assemblies (see photo below) of overhead storage compartments in Boeing 767 airplanes.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Many of the materials in this slideshow are resins or elastomers, plus reinforced materials, styrenics, and PLA masterbatches. Applications range from automotive and aerospace to industrial, consumer electronics and wearables, consumer goods, medical and healthcare, as well as sporting goods, and materials for protecting food and beverages.
Engineers trying to keep track of the ever-ballooning number of materials and machines for additive manufacturing and 3D printing now have some relief: a free searchable database with more than 350 machines and 450 different materials.
At JEC Europe Dow Automotive introduced a new ultra-fast, under-60-second molding cycle time for its commercial-grade VORAFORCE 5300 epoxy resin matrix for carbon composites. It's aimed at high-volume automotive manufacturing.
