The research shows the comparison between two types of polyamide-based (PA) composites and pure, base material. The conducted analysis describes how the additions of carbon fibers and glass microbeads affect the material's properties and its behavior during the bending tests. All samples have been tested in the three main directions available during the FFF process. To extend the scope of the research, additional digital-image-correlation tests and fracture analyses were made. The obtained results indicated a positive influence of the addition of carbon fibers into the material's volume (from 81.39 MPa in the case of pure PA to 243.62 MPa in the case of the PA reinforced by carbon fibers).
该研究展示了两种聚酰胺基(PA)复合材料与纯基础材料之间的比较。所进行的分析描述了碳纤维和玻璃微珠的添加如何影响材料性能及其在弯曲试验中的表现。所有样品均在熔融沉积成型(FFF)工艺可用的三个主要方向上进行了测试。为了扩展研究范围,还进行了额外的数字图像相关测试和断裂分析。所得结果表明,向材料中添加碳纤维具有积极影响(从纯PA的81.39MPa到碳纤维增强PA的243.62MPa)。
