(GMT) have been around for years now, finding a home in automotive interiors
among other applications. But these materials, which consist of short
glass-fiber mat in various thermoplastic base resins, have not made any headway
automotive components where cosmetic, structural, and production concerns have
so far limited their appeal.

plastics have come a long way from their early days in the car’s
less-than-critical components. And today, plastics routinely see use in vital
underhood or structural applications whose mechanical or thermal requirements
would have called for a metal not so long ago. Materials advances over the years
have helped propel plastics into this growing role.
What are the major materials issues confronting design engineers
key issue is accounting for the effects on material of the forming process. For
example, short glass fiber reinforcement increases the stiffness of plastic and
when you mold the material, the final orientation of the glass fibers determines
the properties. With flow analysis, we can predict the final orientation and
then calculate the modulus in different directions. This information can then be
used for structural analysis.
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
In a world that's going green, industrial operations have a problem: Their processes involve materials that are potentially toxic, flammable, corrosive, or reactive. If improperly managed, this can precipitate dangerous health and environmental consequences.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
