【摘要】：采用一定劑量的低能電子束輻照預浸帶并分層鋪放,在不同溫度下對預成型層合板進行熱后固化制備復合材料,研究了輻照劑量及后固化溫度對復合材料層間性能的影響。結(jié)果表明:上表面輻照劑量對復合材料層間剪切強度(ILSS)的影響比后固化溫度的影響大,下表面輻照劑量的影響最小;當總輻照劑量(上下表面劑量之和)為100~130kGy時,復合材料層間剪切強度較高(66.3 MPa);輻照總劑量大于130kGy后,因黏接層平均固化度的增大導致復合材料層間黏接效果變差,層間剪切強度明顯下降;后固化溫度對經(jīng)過低能電子束輻照后復合材料的固化速率影響較大,在滿足預浸帶上下表面完全固化的基礎(chǔ)上,較低的固化溫度能夠改善復合材料的層間黏接性能并使其獲得較高的層間剪切強度。
[Abstract]:In this paper, the prepreg band of a certain dose of low energy electron beam was irradiated and layered to prepare the composite material. The effects of irradiation dose and post-curing temperature on the interlaminar properties of the composite were studied. The results show that the effect of irradiation dose on the interlaminar shear strength (ILSS) of the composites is greater than that on the post-curing temperature, and the effect of irradiation dose on the lower surface is the least. The interlaminar shear strength of composites was higher (66.3 MPa);) when the total irradiation dose (the sum of upper and lower surface doses) was 100~130kGy. When the total irradiation dose is greater than 130kGy, the interlaminar adhesion becomes worse and the interlaminar shear strength decreases obviously because of the increase of the average curing degree of the bonding layer. The post-curing temperature has a great influence on the curing rate of the composite after low energy electron beam irradiation, and on the basis of satisfying the complete curing of the upper and lower surfaces of the prepreg band, Lower curing temperature can improve the interlaminar adhesion of the composites and make them obtain higher interlaminar shear strength.
