In the present work tubular –shaped fiber reinforced composites weremanufactured by using two types of resin epoxy (EP) and unsaturated polyester(UP),each was separately reinforced with glass, carbon and kevlar-49 fibers (filamentand woven roving), hybrid reinforcement composites of these fibers were alsoprepared. The adhesion force test of the prepared specimens was carried out. Theseadhesion forces exhibited a peak value at a percent of hardener/resin (H/R)= 3% forUP matrix with all type of fiber arrangements while 30% was obtained for EP matrix.Such behavior was declined with increase in temperatures. Glass transitiontemperatures were determined from these measurements, and found to be 90°C for EP–glass and 83 °C for UP –glass composites.
