AI总结:

本研究采用RFP熔融沉积成型与LFS立体光刻两种增材技术制备不同纤维增强复合试样,开展多力学性能试验并与传统固化复合材料对比,为航空航天用3D打印结构损伤模型开发提供实验基础。

摘要:

本项目旨在研究采用最新增材制造技术生产的零件与结构的力学性能。试验样件的增材制造采用了纤维增强聚合物(RFP)熔融沉积成型技术,以及高分辨率低力立体光刻(LFS)热固性树脂打印系统。LFS打印采用UV热固性树脂,RFP打印则使用两种不同的丝材:无定形聚碳酸酯碳纤维丝材和半结晶尼龙12玻璃纤维丝材。实验工作中打印了用于拉伸、压缩和剪切试验的试样,此外还探究了这些试样的II型层间断裂行为。研究将这些试样的弹性模量和强度值与烘箱固化的T700G/2510复合材料数据进行了对比。本文的实验工作将进一步拓展,用于开发面向航空航天与空间应用的3D打印结构零件及结构的损伤模型。

英文摘要:

This project is focused on investigating the structural performance of parts and structures produced using the latest additive manufacturing techniques. For additive manufacturing of test coupons, fused deposition modeling of fiber-reinforced polymer (RFP) and high-resolution low-force stereolithography (LFS) thermoset resin printing systems were employed. UV thermoset resin was used for LFS printing, while RFP printing adopted two different types of filaments: amorphous polycarbonate carbon fiber filaments and semi-crystalline Nylon 12 glass fiber filaments. For the experimental work, specimens were printed for tension, compression, and shear tests. Additionally, mode-II interlminar fracture in these specimens was explored. The elastic modulus and strength values of these specimens were compared with the data of oven-cured T700G/2510 composites. The experimental work herein will be extended to develop damage models for 3D-printed structural parts and structures for aerospace and space applications.
