Typical composite results for plasma treated and untreated (as received) fabric are presented in Tables I & II. These fibers are as dissimilar as one could ever anticipate in synthetic polymers. Spectra is ostensibly only carbon and hydrogen, an analog of wax but a polymer of extremely high molecular weight and orientation (30:1 draw ratio). Kevlar is a polyaramid with a variety of chemical elements and groups and is primarily aromatic in structure. By the judicious selection of process gas the fiber surface of either fiber is reengineered to make it compatible with and, if desired, reactive to the resin matrix of choice.The improvements in flexural strength and modulus are the result of an increase in interlaminar shear strength which in the case of the Kevlar was measured only for the plasma treated fabriccomposites.
