“…The radiation curing of resin matrix composites by E‐Beam was initiated in the 1960s , E‐Beam curing technology have achieved a major breakthrough for the composite materials manufacturing by successfully developing E‐Beam curable epoxies, cationic initiator and E‐Beam curing cycles that reduce processing time and cost while meeting the demanding requirements of high‐performance composite structures . Recent years, the research efforts about E‐Beam curing composites mainly focused on high‐energy E‐Beam curing process and composites that match the performance of thermally cured composites .…”

To solve the penetration depth of carbon fiber/epoxy prepreg and irradiation dose uniformity by low-energy E-Beam under 125 keV, the both-side irradiation curing of prepreg was investigated. The results show that there is little thermal effect during the low-energy electron beam irradiation curing process, even though the irradiation dosage reached 300 kGy, only 46.2 C can be tested on the prepreg surface. Due to the low curing temperature, the degree of cure of prepreg was only 61.8% at 300 kGy level of irradiation, and the glasstransition temperature (T g ) was only 48.6 C. The degree of cure and T g can be increased sharply by thermal postcure. After being postcured at 160 C for 30 min, the degree of cure and the T g of prepreg reached 98.5% and 170.4 C, respectively. Interlaminar shear strength testing result indicate that the fabrication process of the composite layer by layer curing by the low-energy E-Beam is a promising cure approach. POLYM.

“…Radiation effects are studied less for transients than for steady state, because of the additional and computational complexities. Recently, they have attracted much more attention, and several excellent reviews on radiation and combined radiation and conduction energy transfer in dispersed media are available 10–23…”

Transient radiative and conductive heat transfer in a translucent medium with isotropic optical properties is investigated. The radiative two-flux equation is coupled with the transient energy equation and both equations are solved simultaneously. Transient solutions are obtained for a plane layer with refractive index equal to or larger than one, and with external convection and radiation at each boundary. Illustrative results obtained with the twoflux method show the effects of changing parameters such as optical thicknesses, refractive index, conduction-radiation parameter, and scattering on the transient temperature distribution within the layer. Results are given at different instances during the transient, and the distribution for the largest time is at or very close to steady state.

“…Recently, polymers have been one of the main research areas owing to their interesting electrical properties and their potential applications in various fields. They can be used as thermal barrier coatings [3,4], and many modern electronic and electrical components, such as connectors, electrochromic displays [5], sensors [6,7], bobbins circuit breakers, batteries, [8,9], electrochromic windows [10], and electromagnetic interference shielding [11], are often based on polyamide engineering plastics and find widespread use in computers, automotive systems [12][13][14], industrial equipments, machinery, thin films, and sporting goods. These products are likely to be found in service conditions where there is an increased chance of ignition.…”

An analysis is developed for computing transient thermal behavior in a layer of polyamide 6T. The radiative two-flux equation is coupled with the transient energy equation, and for the general boundary conditions of external convection and radiation on the layer with diffuse interfaces, it is shown that the two-flux method can be used to predict accurate steady-state temperature distributions. The layer refractive indices are larger than one and internal reflections are included. The analysis includes internal emission, absorption, and isotropic scattering and heat conduction. An advantage of the two-flux method is that isotropic scattering is included without any additional complication and some transient results with large scattering are given to illustrate scattering effects.
