In this study, we use spectra® and HDPET fiber by leno structure to weave Ribbond composites. The surfacial property will be modified by plasma treating with different ratio of gas and treat time. The modified samples were coated by UV curable resin to improve mechanical property of Ribbond composites. From the result shows the strength of Ribbond composites were decreased with the increase of treating time. The strength of HDPET Ribbond lose more than HMWPE Ribbond in the same Plasma treat time. HDPET strength lose 10%, PE lose 6.82% when the same treat time at 4 minute. The contact angle of Ribbond will decrease with the increase the treat time increased. HDPET Ribbond composites wetting property better than HMWPE Ribbond composites.
