Prepregs

Leveraging towpreg to reduce the cost of CMC

High-denier, spread-tow Nextel 610 fiber and novel alumina matrix enable AFP production of Ox-Ox ceramic matrix composites.

Nanomaterials

Graphene 101: Forms, properties and applications

Graphene-enhanced composites find new applications across end markets as the supply chain continues to mature. 

Epoxies

Vitrimers: The reprocessable thermoset

Vitrimers are not classic thermosets and they are not classic thermoplastics, but they behave like both and as such offer the best of both worlds. CW catches up with Mallinda for an explanation.

Defense

Data security in composites manufacturing

The U.S. Department of Defense is imposing new, strict rules on companies that supply composite parts and structures in a defense contract supply chain. Understanding and following those rules will not be trivial.

ESE Carbon Co.’s new carbon fiber wheel uses tailored fiber placement and custom presses to minimize waste and improve scalability.

Compression Molding

Overmolding on the cheap

Innovative injection/compression composites overmolding approach combines smaller injection molded inserts with compression molded parts.

Thermoplastics

Additive Molding promises mass-produced high-performance composites

Arris Composites introduces a patent-pending technology that manufactures high-performance thermoplastic composite components with a combination of additive manufacturing technology and high-speed compression molding. Has mass production of advanced composite components finally arrived?

Thermoplastics

3D printing continuous fiber on the desktop

Additive manufacturing technology company expands offerings to include high-performance composites.

Aerospace

Modular, mobile, multiple robotics poised to change the AFP/ATL paradigm

The German Aerospace Center (DLR) is working on two multi-robot automated fiber and tape placement technologies that could change the paradigm in large-part aerocomposites manufacturing.

Carbon fiber/epoxy for automotive mass reduction, mass production

IACMI precompetitive research explores carbon fiber-reinforced prepreg, SMC with novel matrix for structural passenger-car applications.

Aerospace

Rocket module manufactured with in-situ consolidation survives first flight test

A carbon fiber-reinforced thermoplastic (CFRP) module developed at the Technical University of Munich survived its first launch — and a “hard landing” — in March.

Compression Molding

Compression presses keep evolving in response to composites innovation

Shorter, lighter, smaller footprint Fiberpress machines are ideal for facilities with lower ceilings, automated production lines.

Fabrics/Preforms

Injection-forming for high-performance, unitized thermoplastic structures

Combining braided tape, overmolding and form-locking, herone produces one-piece, high-torque gear-driveshaft as demonstrator for broad range of applications.
