Abstract
Future Army systems have been envisioned that are lighter, faster, and more transportable than their existing counterparts. Glass-fiber reinforced composite materials are envisioned as a solution to meet both structural and ballistic requirements for emerging lightweight army ground vehicle applications. The interphase of these composites may only compose as little as one percent of the total volume of material, but plays a critical role with respect to the overall durability and mechanical performance. In addition to the well-known effects of the fiber-matrix interphase on composite performance, it is now believed that the interphase may control the ballistic properties of composites used in lightweight armor applications. Thus the origin and properties of the sized glass fiber-matrix interphase must be quantified to develop new sizings with optimal ballistic and structural performance. Previous research at our labs has identified the amount and chemical composition of the bound and extractable portions of a commercial sizing using NMR, FTIR, and HPLC techniques. Here, the thermal and mechanical properties of the interphase were further examined using a model system to represent the bound phase of the sizing materials. The previously performed chemical characterization was used to guide the formulation of a model bound fraction of interphase material for typical epoxy compatible commercial silane-based sizing formulations.
