“…On the other hand, when it assumes to be like a complex springs with different elasticities and their limits of a series connection constructed with both monomers in PC polymers and Ti/PC interface layer, as well as parallel connection of PC/CF interface, it can explain the elasticity transition (n = 1.2 for Ti/CF/PC). The stress-strain cureves with n > 1 have been also obtained for compressive test of C/C composite 49) , as well as tensile test for carbon ber 46) and Polyethylene 50) .…”

A new titanium (Ti)/polycarbonate (PC) joint [Ti/EBCF/PC] internally connected by homogeneous low potential electron beam irradiation (HLEBI) activated cross-weave carbon ber (6 μm in diameter) cloth insert taking advantage of broad CF surface area had been developed. Applying HLEBI dose in the range of 0.043 to 0.43 MGy to the bare CF half-length prior to dipping in the thermoplastic PC molten resin enhanced ultimate tensile strength (σ b) of Ti/EBCF/PC over that without HLEBI [Ti/CF/PC]. The 0.30 MGy dose appeared to be near the optimum resulting in σ b of 20.7 MPa, an increase of 3.0, 3.9 and 21.1 times higher than that of Ti/CF/PC, with glue only [Ti/Glue/PC], and with spontaneous adhesion without glue [Ti/PC], at 7.00, 5.30, and 0.98 MPa, respectively. Moreover, regardless of HLEBI treatment, introduction of the CF insert into the joint prevented abrupt brittle fracture compared to the Ti/PC joint. The corrected ultimate tensile strength (c σ b) de ned as that of the 60 vol% CF-containing PC cross section portion calculated by rule of mixtures was also raised by the 0.30 MGy HLEBI to c σ b = 195 MPa (Ti/EBCF/CFRPC); 6.89 and 31.7 times higher than that of Ti/CF/CFRPC and Ti/PC at 28.3 MPa and 6.16 MPa, respectively. The HLEBI probably enhanced the ability to adhere the CFs to dif cult to adhere thermoplastic PC to generate the tremendously large friction force, with the aim of raising the safety level of lightweight material with high resistance to fracture for airplanes and automobiles.

The EBM 350 keV/10mA is an electron irradiation facility located at the Centre for Accelerator Science and Technology (PSTA). The EBM generates the electrons with energy of 350 keV and the beam current of 10 mA. This generated electron beam can induce x-rays radiation when passing through materials. It is dangerous for workers if the radiation dose exceeds the dose threshold. The previous study has investigated the x-rays radiation in the EBM facility. However, it implemented an analytical approach and applied the high-Z material tabulation data for the x-rays source definition. In this work, we present a different approach using particle transport simulation. The Particle and Heavy Ion Transport code System (PHITS) was utilised to obtain the x-rays source data as well as its dose distribution in the EBM facility. Based on the PHITS simulation, the x-rays are induced by the interaction between electron beams and the EBM’ window through atomic fluorescence and bremsstrahlung mechanism, with the total reaction rate density of 2.6437 × 1013 reactions/cm3s. The x-rays’ maximum dose rate of 1.4659 × 104 µSv/s is located around the window, and it decreases along with the position from the window. The x-rays dose rate in the preparation room (12 m away from the x-rays source, behind 45 cm concrete wall) was 7.4975 × 10−2 µSv/s. It exceeded the permissible dose threshold. Therefore, a radiation shield or the working-duration limits is required for the workers’ safety.
