Use of KEVLAR ® 49 in Aircraft Components

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...

Managing Life-Cycle Information of Aircraft Components

When an aircraft component needs replacement of a serially controlled item, a maintenance officer in the U.S. navy uses the Scheduled Removal Component (SRC) card to confirm the component's life cycle, to verify that the part is ready-for-issue, and to verify how many flight-hours it still has left. Unfortunately, replacement components are often missing the SRC cards. Further, when the cards a...
