In order to improve and enhance its hydrophilic and adhesion, this study used atmos- phere plasma to modify the surface of PTFE with the application of different plas- ma powers and rolling rates. Moreover, the study used the contact angle test in Ar gas under the power of 1.3kw and rolling rate 2L/min as the optimal condition. Afterwards this study spread two UV glue Aliphatic Urethane Diacrylate N6113, N Series, and Aliphatic Urethane Diacrylate diluted in 25% IBOA, 6148J-75, J Series to the PTFE film. The next step was to use FTIR-IR to modify and observe the surface of PTFE in the modified 3476cm-1 with the absorption peak of OH functional groups. XPS instrument alyzer identified that modified PTFE produ- ced oxygen. Glass fiber Cloth(GFC) was separately modified by three different Silane . These three Silane are Benzylamino-silane (A1128), N-[2-Vinylbenzyl]- 2-aminoethyl-3-aminopropyltrimethoxysilane hydrochloride oligomer (KBM974), and 3-trimethoxysilyl propryl methacrylate (KBM503). With the change of differ- rent consistency, this study used soaking method to modify the surface of Glass fiber clothe(GFC). The results showed that it was better for the adhesion with the consistency of KBM503 was 1 %. In addition, this study used modified PTFE and GFC to proceed UV curing. This study revealed that the application of N series of agglutination was helpful for the stick of PTFE/GFC composite and got the high- est strip strength 0.712Mpa and the hundred square strength was 95％. With the comparison of unmodified materials of strip strength, the effect was above 5 times better than the unmodified materials. The purpose of this study was to observe the surface with stripping by using SEM.
