Method for improving internal quality of R angle of non-autoclave molded part

The invention discloses a method for improving the internal quality of an R corner of a non-autoclave molded part, and relates to the technical field of curing molding. In the process of paving and pasting the prepregs, fiber tows are placed at the position of an R angle when N layers of prepregs are paved, and the fiber tows extend out of the two ends of the paving layer in the length direction and are connected with a breathable felt which is subsequently paved; gas existing in the prepreg, gas wrapped in the prepreg in the paving process, small molecule gas generated by chemical reaction in the curing process and the like can be discharged through glass fiber tows, internal quality defects such as loosening and layering of a workpiece at the R angle position are prevented, and the internal quality of the R angle is remarkably improved. 本发明公开了一种改善非热压罐成型制件R角内部质量的方法，涉及固化成型技术领域。通过在铺贴预浸料的过程中，每铺设N层预浸料即在R角位置放置纤维丝束，并使纤维丝束从铺层的长度方向的两端伸出，与后续铺放的透气毡相连，能够将预浸料中本身存在的气体、铺贴过程中裹入的气体以及固化过程中化学反应产生的小分子气体等通过玻璃纤维丝束排出，防止制件在R角位置出现疏
