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

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.
