Unidirectional and balanced cross-ply laminates were fabricated via slurry impregnation, drum winding, and autoclave consolidation. The as-fabricated laminates exhibited a bulk density of 1.94 \u00b1 0.16 g\/cm3 and an apparent porosity of 23.8 \u00b1 2.5%. For the [0]8 laminates, the mean tensile strength was 827.0 MPa at room temperature, 832.1 MPa at 371 \u00b0C, 745.7 MPa at 427 \u00b0C, and 365.5 MPa at 538 \u00b0C. Temperature-dependent failure modes shifted from predominantly longitudinal splitting up to 371 \u00b0C, to mixed splitting and fiber-dominated tensile fracture within the gauge section at 427 \u00b0C, and finally to brittle, fiber-dominated tensile fracture with no apparent fiber pull-out at 538 \u00b0C. Thermo-oxidative studies showed that the net mass loss of the coupons remained below 0.4% after 1000 h at 316 \u00b0C but reached approximately 4.7% after 336 h at 371 \u00b0C. The sections examined after exposure at 371 \u00b0C showed non-uniform filament thinning. These results establish a baseline mechanical and thermo-oxidative characterization for the proposed material system and identify prolonged oxidation as a limitation requiring further evaluation.<\/jats:p>","DOI":"10.3390\/polym18192448","type":"journal-article","created":{"date-parts":[[2026,10,8]],"date-time":"2026-10-08T08:34:25Z","timestamp":1791448465000},"page":"2448","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Geopolymer-Derived Aluminosilicate Matrix Composites Reinforced with Continuous Nickel-Coated Carbon Fibers: Tensile Properties and Thermo-Oxidative Behavior"],"prefix":"10.3390","volume":"18","author":[{"given":"Michal","family":"Jasiczek","sequence":"first","affiliation":[{"name":"GE Aerospace, Al.
