The paper presents a study of the effect of constant magnetic field on composites used in building industry.
David P. Maass, an aviation engineer and an expert on composites, said that one method was ultrasonic testing, in which high-frequency sound waves, too high for the human ear to hear, are pumped into a composite structure.
The calculated results are validated by comparison with measurements on composites fabricated by gas pressure infiltration of aluminum into preforms of selected compositions of particle mixtures.
A comparative study performed on composites and pure PPy has led to two main conclusions: on one hand, the microstructure of the GNS/PPy composites is dependent on the loading of PPy.
Unlike Anna Deavere Smith, who interviewed dozens of people for her one-woman shows "Fires in the Mirror," about the Crown Heights riots of 1991, and "Twilight: Los Angeles, 1992," about the Rodney King riots, Mr. Hoch bases most of his characters on composites of people he knows.
A collaboration with Airbus on composites led to an order to design and build wing parts for the giant A380 jet, launched in 2005.The aerospace venture might seem to sit awkwardly in a company whose mainstay is selling car parts but Mr Stein says there are "soft synergies" between the two divisions.
This complexity is meant to engender operations on composites of composite units.
We concentrate on composites with circular or elliptic cylindrical inclusions.
The researchers, who plan to test the meshes on composites that resemble human skin, hope that they will eventually lead to smart wound dressings that could prevent infections.
Attention is focused on composites involving ageing constituents.
It is found that thinner reinforcing fibers do not definitely confer better fracture toughness on composites.
