Vectran&reg fibers; made using liquid crystalline polyester; were treated with pulsed XeCl excimer laser (308 nm) to alter their surface characteristics and; thus; improve their adhesion to epoxy resin. The treatments were carried out in air using varying numbers of pulses at different laser fluences. The effects of laser treatment on the fiber surface topography; chemistry and wettability have been investigated. Fiber/epoxy resin interfacial shear strength was measured using the microbead test. The surface roughness was characterized qualitatively and quantitatively using scanning electron microscopy (SEM) and atomic force microscopy (AFM); respectively. Changes in the surface energy were characterized using the Wilhelmy technique. Based on the SEM micrographs; the threshold fluence for the formation of surface structure was found to be less than 36 mJ/(pulse * cm2). The laser treatments at fluences higher than the threshold fluence introduced periodic roll (wavy) structures on the fiber surface transverse to the fiber axis. From the AFM results; the fiber surface roughness was found to increase by up to 3.5 times the control fiber after the laser treatment. The dispersion component of the surface energy decreased; while the acid-base component of the surface energy increased significantly from 0 to 8.8 mJ/m2 after the laser treatment. The Vectran&reg fiber/epoxy resin IFSS increased by up to 75% after the laser treatment. This improvement is mainly attributed to higher surface roughness of the fiber;
