In the present study, novel woven reinforced single polymer composites (WSPC) based on polyamide 6 (PA6) is developed via a combination of powder-coating of PA6 textile reinforcements with PA6 empty microcapsules (EMC) and compression molding techniques. Activated anionic ring-opening polymerization of ε-caprolactam was employed to synthesize the PA6-EMC which was transformed during the compression molding into WSPC matrix without damaging the PA6 textile reinforcements. A promising novel class of PA6 woven fabrics, stitched plain, which are patented by Jakob Müller company AG® were used as reinforcements. The tensile properties of stitched plain reinforced WSPC were studied and compared to ones reinforced by the plain-woven structure and the PA6 neat matrix reference materials. The parametric studies are performed on the stress field along the elements of reinforcements, using image processing to correlate the influence of reinforcement architectures with the failure mechanism of WSPC.

新型缝合平纹织物增强聚酰胺6基单聚合物复合材料的开发

在本研究中,通过将PA6纺织增强材料的粉末涂料与PA6空微胶囊(EMC)和压缩成型技术相结合,开发了基于聚酰胺6(PA6)的新型机织增强单聚合物复合材料(WSPC)。ε-己内酰胺的活化阴离子开环聚合用于合成PA6-EMC,该PA6-EMC在压缩成型过程中转变为WSPC基质,而不会损坏PA6织物增强材料。JakobMüller公司AG®申请了一种很有希望的新颖PA6编织平纹机织物作为增强材料。研究了缝合的平纹增强型WSPC的拉伸性能,并将其与平纹组织结构和PA6净基体参考材料增强后的拉伸性能进行了比较。
