Polyester resins: The basics - CompositesWorld
WEBFeb 2, 2020 · It is usual to refer to unsaturated polyester resins as “polyester resins,” or simply as “polyesters.”. There is a whole range of polyesters made from different acids, glycols and monomers, all having varying properties. There are two principle types of polyester resin used as standard laminating systems in the composites industry.

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.
Materials & Processes: Composites fibers and resins
WEBMar 14, 2016 · Compared to legacy materials like steel, aluminum, iron and titanium, composites are still coming of age, and only just now are being better understood by design and manufacturing engineers. However, composites' physical properties-combined with unbeatable light weight-make them undeniably attractive.
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 ...
Composites in commercial aircraft engines, 2014-2023
WEBJan 6, 2015 · Based on growing aircraft production rates, especially for commercial aircraft, our previously noted (and conservative) 2014 estimate of nearly 1,680 MT of composite engine components, worth more than US$1.1 billion, will grow, by 2023, to more than 2,665 MT of structures, valued at US$1.7 billion.
Materials & Processes: Fabrication methods - CompositesWorld
WEBMar 23, 2016 · Composite fabrication processes typically involve some form of molding, to shape the resin and reinforcement. A mold tool is required to give the unformed resin/fiber combination its shape prior to and during cure. Click on “Tooling” for an overview of mold types as well as materials and methods used to make mold tools.
Materials & Processes: Tooling for composites
WEBMar 23, 2016 · A key issue with tooling for composites is the phenomenon of coefficient of thermal expansion (CTE) mismatch. Here, composite tooling has the advantage over metals. Composite tools made from tooling prepregs have a CTE close to the part CTE. During cure, shrinkage and thermal expansion of the tool and part will be very similar.
