Carbon Fiber Multiaxial Fabric is a stitched, non-crimp reinforcement built from straight, non-woven carbon fiber layers oriented at 0°, 90°, and ±45°, joined with polyester stitching threads. Composite manufacturers sourcing carbon fiber multiaxial fabric benefit from parallel, non-buckled fiber orientation that improves resin flow and delivers higher mechanical performance per layer than a comparable woven carbon fabric.
Carbon Fiber Multiaxial Fabric Product Description
This carbon fiber multiaxial fabric is constructed by laying straight, untwisted carbon fiber tows in the warp (0°), weft (90°), or bias (±45°) directions, then stitching the layers together with polyester thread rather than weaving them. Because the fibers stay straight instead of crimping over and under one another, each layer can more fully develop its tensile and compressive strength once impregnated with resin. Configurations range from single-axis (unidirectional) fabric through biaxial, triaxial, and quadraxial constructions, with total areal weight from roughly 100 g/m² to over 800 g/m² depending on the code selected, so laminate schedules can be built up in fewer plies for a target thickness.
Carbon Fiber Multiaxial Fabric Product Application
Carbon fiber multiaxial fabric is used across ship and marine structures, wind turbine blade spar caps and shear webs, construction reinforcement, and other high-performance composite parts where a defined fiber orientation is engineered into the laminate. It is compatible with infusion, resin transfer molding (RTM), and mould pressing processes, and can be paired with epoxy, polyurethane, or vinyl ester resin systems depending on the target part’s service temperature and chemical exposure.
Carbon Fiber Multiaxial Fabric Product Features
- Non-buckling yarn: straight, parallel carbon fiber tows develop the material’s full mechanical properties instead of losing strength to weave crimp
- Designable construction: each ply’s fiber orientation, areal weight, and stacking sequence can be specified to match a laminate’s load path
- Good resin conductivity: the stitched, non-woven structure allows faster resin flow and more complete wet-out during infusion than a tightly woven fabric
- High lamination efficiency: multiple fiber orientations combined in a single multiaxial ply reduce the number of individual layers needed to reach a target laminate schedule

Sourcing Carbon Fiber Multiaxial Fabric for Composite Manufacturing
Composite fabricators evaluating carbon fiber multiaxial fabric alongside other carbon fiber reinforcement products typically confirm areal weight per orientation, stitch gauge, and resin compatibility against their laminate design before qualifying a new supplier. Buyers moving from a woven carbon fabric to a multiaxial construction often run a small trial panel first, since resin uptake and cure behavior can differ from a plain or twill weave even at a similar total fiber weight.
Fiber orientation tolerance and areal weight per layer are commonly checked against reference test methods such as ASTM D4018, which composite buyers can use as a comparison point when reviewing technical data sheets from different multiaxial fabric suppliers. Because supply continuity matters for production planning, buyers sourcing carbon fiber multiaxial fabric for recurring orders also typically ask about lead time, roll width options, and packaging before moving from sample quantities to a standing order.
Frequently Asked Questions
What fiber orientations are available in carbon fiber multiaxial fabric?
Constructions include unidirectional (0°), biaxial (0°/90° or ±45°), triaxial, and quadraxial layups, with the areal weight of each orientation selectable to match a laminate design.
How is carbon fiber multiaxial fabric different from woven carbon fabric?
The carbon fiber tows are laid straight and stitched together rather than woven, so the fibers do not crimp over and under each other. This generally improves mechanical performance and resin flow compared with a woven construction at a similar fiber weight.
Which resin systems is this fabric compatible with?
It is compatible with epoxy, polyurethane, and vinyl ester resin systems, and can be processed by infusion, resin transfer molding (RTM), or mould pressing.
What industries use carbon fiber multiaxial fabric?
Typical applications include marine and shipbuilding structures, wind turbine blade components, construction reinforcement, and other composite parts that call for a defined, high-performance fiber orientation.
Can areal weight and stacking sequence be customized?
Yes. The gram weight of each orientation and the stacking sequence can be specified by design, allowing the fabric to be tailored to a specific laminate schedule.
