CURRENT CARBON FIBERS EXIST WITH MODULI UP TO 140 MSI OR STRENGTHS APPROACHING 1 MSI.

CURRENT CARBON FIBERS EXIST WITH MODULI UP TO 140 MSI OR STRENGTHS APPROACHING 1 MSI. THESE TWO EXCEPTIONAL PROPERTIES DO NOT EXIST SIMULTANEOUSLY WITHIN ANY FIBER HOWEVER. TYPICALLY, HIGH MODULUS FIBERS EXHIBIT LOW STRENGTH WHILE HIGH STRENGTH FIBERS EXHIBIT LOW MODULUS. THE THRUST OF THE PROPOSED PROGRAM IS TO DETERMINE THE RANGE OF THERMAL AND MECHANICAL PROPERTIES AVAILABLE THROUGH HYBRIDIZATION. THE PROPOSED EFFORT WILL EVALUATE ANALYTICALLY THE RANGE OF PROPERTIES AVAILABLE THROUGH TWO HYBRIDIZATION SCHEMES. FIRST, HIGH MODULUS AND HIGH STRENGTH FIBERS WILL BE COMBINED IN A SINGLE PLY. SECOND, PLIES REINFORCED WITH HIGH MODULUS FIBERS WILL BE COMBINED IN A LAMINATE WITH PLIES REINFORCED WITH HIGH STRENGTH FIBERS. WITHIN THE ANALYSIS, POLYMERIC, CARBON, AND METALLIC MATERIALS WILL BE UTILIZED AS THE COMPOSITE MATRIX MATERIAL. THE RESULTS OF THESE EFFORTS WILL QUANTIFY THE RANGE OF PROPERTIES AVAILABLE THROUGH HYBRIDIZATION.
