Archery: carbon fiber arrows and bolts, stock (for crossbows) and riser (for vertical bows), and rail. As a filament for the 3D fused deposition modeling printing process, [45] carbon fiber-reinforced plastic (polyamide-carbon filament) is used for the production of sturdy but lightweight tools and parts due to its high strength and tear length ...
The equation below shows the creep strain of a filled material: [13] ε c (t)/ε m (t) = E m /E c. where: ε c (t) = is strain of filled polymer ε m (t) = is strain of matrix or unfilled polymer E m = is Young's Modulus of matrix E c =is the Young's Modulus of filled polymer. The better the filler bonds with the matrix the better creep ...
A desktop FFF printer made by Stratasys. Fused deposition modeling was developed by S. Scott Crump, co-founder of Stratasys, in 1988. [6] [7] With the 2009 expiration of the patent on this technology, [8] people could use this type of printing without paying Stratasys for the right to do so, opening up commercial, DIY, and open-source 3D printer applications.
Recycling codes on products. Recycling codes are used to identify the materials out of which the item is made, to facilitate easier recycling process.The presence on an item of a recycling code, a chasing arrows logo, or a resin code, is not an automatic indicator that a material is recyclable; it is an explanation of what the item is made of.
As seen in the table below, Nylon 11 has lower values of density, flexural and Young's modulus, water absorption, as well as melting and glass transition temperatures. Nylon 11 is seen to have increased dimensional stability in the presence of moisture due to its low concentration of amides. Nylon 11 experiences 0.2-0.5% length variation and 1. ...

The printing cylinders are usually made from copper plated steel, which is subsequently chromed, and may be produced by diamond engraving; etching, or laser ablation. Gravure printing is known for its ability to produce high-quality, high-resolution images with accurate color reproduction and using viscosity control equipment during production.
