Abstract

One of the remaining barriers to the wide acceptance and implementation composites in structural applications is the high cost associated with the manufacturing of structural composite parts. Preform assembly, as it is currently done, is the single most costly step in the fabrication of fiber-reinforced polymer composites. Current techniques of assembling preforms for most liquid resin infusion processes involve the hand lay-up of individual fiber plies in a molding tool. An inexpensive and effective means to connect a large number of individual fiber plies so that the desired preform shape is achieved has been developed and demonstrated by Solectria Corporation. The objective of this effort is to investigate and evaluate the performance of preforms created by using this preforming technology with respect to composite armor requirements. Aspects of the binder behavior that will be investigated include: 1) The mechanism in which the binder interacts with the type of glass used in composite armors. 2) The compatability between the binder and the fiber sizing and 3) The effects of binder chemistry, particle size and concentration on the properties of the stabilized preform and molded parts. BENEFITS: The project will result in a preforming technology package capable of producing preforms for market such as: 1) Add-on composite armor packages for fielded systems, 2) body armor products, 3) the Crusader program, 4) the Future Scout vehicle and 5) other automotive products for the army.
