Material Testing Data for Coreless Filament Winding Using Small-Scale, Star-Type Specimens

To understand the fabrication influence on mechanical properties and to compare different material combinations, 5 star-type composite specimens were tested. Each specimen was fabricated using coreless filament winding (CFW) and exhibits a bundle cross-section of 20mm. The star specimen replicates a typical CFW system with fiber interaction at different locations and similar uncertainties as actual building components derived from the fabrication process and/or material inconsistencies. The specimens were tested in compression, each data point consists of the standard force, deformation amount, and testing time. Five specimens were used: Specimen 1 consists of carbon fibers with petrochemical resin as a point of reference, Specimen 2,3, and 4 are based on a combination of flax fiber and petrochemical resin and specimen 5 combines flax fibers with bio-based resin. The data serves as a base for the evaluation of the fabrication process and equipment, the structural performance and to compare the environmental impact of different material combinations using Life Cycle Analysis (LCA) indices.

为探究制造工艺对机械性能的影响并对比不同材料组合，本研究对五颗星型复合材料试样进行了测试。每个试样均采用无芯纤维缠绕法（CFW）制成，并展现出20mm的束状横截面积。星型试样模拟了典型的CFW系统，其中纤维在不同位置的相互作用以及由于制造过程和/或材料不均匀性所导致的与实际建筑构件相似的误差均得到体现。试样在压缩条件下进行测试，每个数据点包括标准力、变形量和测试时间。共使用了五个试样：试样1由碳纤维和石油化工树脂组成，作为参照物；试样2、3和4基于亚麻纤维与石油化工树脂的混合；试样5则将亚麻纤维与生物基树脂相结合。这些数据为评估制造工艺和设备、结构性能以及通过生命周期分析（LCA）指标对比不同材料组合的环境影响提供了基础。
