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.
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.
Core materials: The basics - CompositesWorld
WEBFeb 20, 2020 · Core materials: The basics. Core materials available for composite sandwich structures range from paper, aluminum and thermoplastic honeycomb cores to foams and more. Editor’s note: This content was originally published on NetComposites.com. NetComposites was acquired by CompositesWorld’s parent company, Gardner Business Media, in February ...
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.
Pultrusion: The basics - CompositesWorld
WEBFeb 20, 2020 · In a pultrusion process, fibers are pulled from a creel through a resin bath and then on through a heated die. The die completes the impregnation of the fiber, controls the resin content and cures the material into its final shape as it passes through the die. This cured profile is then automatically cut to length.
The making of glass fiber - CompositesWorld
WEBJun 1, 2020 · KraussMaffei Composites Technology Overview During this webinar, the audience will be introduced to a variety of fiber composite technologies — as well as the machines and equipment — from short fibers to continuous fibers, from thermoset to thermoplastic, as well as the according process technology, including a special focus on long-fiber injection (LFI) and structural composite spray (SCS).
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.
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.
