The use of carbon fiber to improve the fracture toughness of 3D-printed fused filament fabricated carbon fiber/ABS composites was effective in loadings up to 25 percent, according to research detailed in a May 10 ANTEC® presentation. Optimal results were achieved with 10 percent carbon fiber load.
Researchers gauge impact of fibers in multiple applications
The May 12 composites session featured several talks characterizing fiber-breakage mechanisms and developing predictive models for discontinuous/short-fiber injection molding materials. It’s well established both that retained fiber length has a major impact on mechanical properties of composites and that, by its nature, injection molding provides many opportunities to break fibers.
Advances in chemistry improve film recyclability, precision of automotive parts and even asphalt
From flexible and rigid packaging to mobility and roads, the boundaries of ethylene polymers are poised to expand and create more sustainable options for everyday uses, according to Dow research presented at ANTEC® 2021 on May 6.
Large printed water drainage parts would speed repairs and cost less than conventional versions
Large-scale 3D printing is being evaluated to repair water-diverting highway culverts, according to Sunil Bhandari of the University of Maine, speaking in a virtual ANTEC® presentation on May 10. An experimental culvert diffuser will be installed in Maine in July and tested in October when the autumn rains arrive.
