In order to evaluate the influence of sheet electron beam irradiation (SEBI) with low potential on water absorption in nylon6, the mass of water absorption in nylon6 has been measured. The SEBI decreases the saturated mass of water absorption in nylon6 and also decreases the initial absorption rate of water, as well as the mass of absorbed water in nylon6 for each treatment time. Based on the results of ESR and XPS, the SEBI forms dangling bonds and then decreases the electrical polarization of nylon6 molecules, resulting in decreasing the mass of absorbed water in nylon6.

Effects of silane coupling treatment and electron beam (EB) irradiation on bending test of glass fiber reinforced epoxy polymer (GFRP) thick sheet were studied. EB irradiation increased the bending strength and its strain of GFRP thick sheet with silane coupling treatment. EB irradiation also enhanced the apparent hardening modulus (ds/de) of bending deformation and increased the deformation energy of GFRP thick sheet with silane coupling treatment. The deformation energy depends on the strain improvement at the maximum bending stress of epoxy resin and glass fiber and the interfacial friction force.

Influences of electron beam (EB) irradiation on magnetostriction and its susceptibility of Fe 2.6 Sm alloy thin films have been investigated. The alloy thin film deposited on a (100) plane of a silicon wafer is prepared by using a direct current magnetron sputtering apparatus. The irradiation enhances compressive magnetostriction and its susceptibility. The large magnetostriction of the irradiated Fe 2.6 Sm sample occurs, because the irradiation prevents generating the Fe 3 Sm crystalline with small magnetostriction. On the other hand, the high susceptibility is explained by randomization, induced by EB irradiation, of Fe 2.6 Sm amorphous sample, where the magnetic moment rotates easily.
