The state of recycled carbon fiber | CompositesWorld
WEBSep 4, 2019 · The case for recycled carbon fiber is a complicated one. The industry is built on the hope of solving problems — namely, the desire to keep carbon fiber waste out of landfills and to fill a potential gap between carbon fiber supply and demand. It is commonly estimated that around 30% of produced carbon fiber ends up as waste.
Composite submersibles: Under pressure in deep, deep waters
WEBMay 10, 2017 · Thus, in the event of catastrophic failure of a submersible at any depth greater than even 250m, deepsea water pressure would instantly kill every passenger on board. And this is the primary concern of OceanGate and, by extension, Spencer Composites. Cyclops 2 faces potential failure in any one of …
Estimating composite properties using data from similar materials

The making of glass fiber - CompositesWorld
WEBJun 1, 2020 · Step 3: Fiberization. Molten glass exits the furnace at ≈1340°C/2444°F and is extruded through heated bushing plates (top image), which have 200 to 8,000 very small orifices, or nozzles. The winders (lower part of bottom image) apply tension to the extruded glass, drawing it out into thin filaments.
Pultrusion: The basics - CompositesWorld
WEBFeb 20, 2020 · Although pultrusion is a continuous process, producing a profile of constant cross-section, a variant known as “pulforming” allows for some variation to be introduced into the cross-section. The process pulls the materials through the die for impregnation, and then clamps them in a mold for curing. This makes the process non-continuous, but ...
The outlook for carbon fiber supply and demand - CompositesWorld
WEBNov 30, 2021 · Tony and Dan estimate that in 2021, global demand for all CF is 113,800 MT. By 2026 that figure is expected to increase to 180,400 MT. Recall that Tony and Dan estimate CF supply from existing facilities in 2026 reaching only 125,150 MT, which creates a potential CF shortfall of 55,250 MT by 2026, with signs of this supply deficit appearing as ...
