The invention relates to the technical field of composite material curing preparation, in particular to a C-shaped beam curing process for improving R-angle defects and a C-shaped beam prepared through the C-shaped beam curing process. According to the invention, after the pre-forming body is paved and prepared, during vacuum forming and packaging, the glass fabric prepreg of the same resin system is added in the composition of the laminated layer, so that the slippage phenomenon of the pre-forming body in the curing process can be reduced, and the glass fabric prepreg is convenient to assemble and disassemble through the isolation of the lower isolating membrane and the upper isolating membrane. And on the other hand, the added glass fabric prepreg provides pressure for the R corner where pressure is dispersed, in combination with the position arrangement of the air guide wires, assistance is provided for discharging of volatile components in the curing process, the R corner defects of pores and layering in a workpiece are finally reduced, and the quality of the workpiece is improved.

    本发明涉及复合材料固化制备技术领域,尤其涉及一种改进R角缺陷的C型梁固化工艺及其制备的C型梁。本发明中预成型体铺贴制备完毕,在真空成型封装时,增添同树脂体系的玻璃织物预浸料在叠层的构成中,这样可减少预成型体在固化过程中出现的滑移现象,且通过下隔离膜和上隔离膜的隔离也便于玻璃织物预浸料的装拆。另一方面,增添的玻璃织物预浸料为压力分散的R角处提供了压力,结合导气丝的位置设置,在固化过程中为挥发分的排出提供了帮助,最终减少了制件中孔隙和分层的R角缺陷,提高了制件的质量。
