Solvent-free release a good match for wind blade molding
5/21/2009

Lightweight, stable large-tool concept requires no master model
4/24/2009

After two years of testing, partners Advanced Composites Group (ACG, Tulsa, Okla.) and GrafTech (Parma, Ohio) are commercializing the ACG GRAFOAM FPA-20 tooling system, a new concept in dimensionally stable, low-mass, high-temperature-compatible composite tooling. The system’s foundation is carbon foam.

Tooling
1/8/2009

The molds used for forming composites, also known as tools, can be made from virtually any material. For parts cured at ambient or low temperature, or for prototyping, where tight control of dimensional accuracy isn’t required, materials such as fiberglass, high-density foams, machinable epoxy boards or even clay or wood/plaster models often are suitable. Tooling costs and complexity increase as the part performance requirements and the number of parts to be produced increase.

New metal coating to optimize composite tooling
5/1/2008

Near the end of its development cycle, this nanostructured metal overlay promises to extend the working life and improve the cost-effectiveness of carbon/epoxy tooling.

Aircraft interior bins benefit from fast-heat, fast-cool tool
3/1/2008

Airbus Industrie (Toulouse, France) wanted to cut cycle time off the production of interior storage bin doors for its A320 and A380 commercial airplanes and identified part cooling in the mold as the most likely source of potential time savings. The doors, about 1m long, are fabricated of a glass fiber prepregged with

Carbon/BMI and carbon foam form Invar alternative
1/1/2008

For years, Invar steel has been the material of choice for tooling that must endure repeated autoclave cycling in volume part production. Invar's disadvantage is its relatively high density and resulting large mass. As processors move away from hand layup and toward automated fiber and tape placement, there is a

Tooling Update: New dimensions in tooling
1/1/2008

Nanoenhancements, out-of-autoclave strategies and low-pressure RTM headline efforts to increase mold quality and productivity and cut tool cost.

JEC COMPOSITES 2007 Highlights
5/1/2007

Advanced composites make notable marks not only in traditional aerospace apps, but in automotive, sport and infrastructure arenas as well.
