Mechanical Properties of Boron and Kevlar-49 Reinforced Thermosetting Composites

Glass reinforced thermosetting composite materials are now widely usUUed in building and construction applications. However, the adoption of Boron and Kevlar based composite materials in this industry has been very slow, and the main reasons are lack of previous experiences to assess the durability of such composite products and understanding of their properties by designers. In order to fill t...

Ballistic Impact Response of Kevlar 49 and Zylon Under Conditions Representing Jet Engine Fan Containment

A ballistic impact test program was conducted to provide validation data for the development of numerical models of blade out events in fabric containment systems. The impact response of two different fiber materials Kevlar 49 (E.I. DuPont Nemours and Company) and Zylon AS (Toyobo Co., Ltd.) was studied by firing metal projectiles into dry woven fabric specimens using a gas gun. The shape, mass...

Physicochemical properties of bacterial surfaces.

Streptococcal M protein is one of the best characterized anti-phagocytic surface molecules. The protein has a coiled fibrillar structure extending outwards about 600 nm from the streptococcal cell wall. The anti-phagocytic nature of the M protein appears to be related to two properties: ( a ) its ability to bind fibrinogen and the D family of its degradation products, thereby preventing deposit...
