A wide range of polymers are now produced in glass-filled varieties, including polyamide (Nylon), acetal homopolymers and copolymers, polyester, polyphenylene oxide (PPO / Noryl), polycarbonate, polyethersulphone [4] Bulk moulding compound is a pre-mixed material of resin and fibres supplied for moulding. Some are thermoplastic or thermosetting ...
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 ...
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 fibres are usually glass (in fibreglass), carbon (in carbon-fibre-reinforced polymer), aramid, or basalt. Rarely, other fibres such as paper, wood, boron, or asbestos have been used. The polymer is usually an epoxy , vinyl ester , or polyester thermosetting plastic , though phenol formaldehyde resins are still in use.
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.

Continuous form paper is used in some of the fastest types of printing systems, some of which print text at a rate of 20,000 lpm (lines per minute). This will produce about 400 pages per minute, using about 8–11 large boxes of paper for every hour of printing (affected by character density, and other details such as paper weight).
