Hexcel® HiMax® Fiberglass E-Glass Unidirectional Fabric • 35.39oz (≈1200gsm) • 49" Width

Hexcel® HiMax® Unidirectional E-Glass 1200gsm is a premium heavy-weight reinforcement designed for structures that demand maximum strength along a single primary load direction. The non-crimp UD architecture keeps fibers straight for superior mechanical properties, while the 35.39oz (≈1200gsm) areal weight and 49" width enable rapid laminate build-up in demanding marine, wind energy, automotive, and industrial applications.

Key advantages

• High axial performance: Predominantly 0° fiber orientation provides outstanding tensile and compressive strength along the length of the laminate.
• Non-crimp construction: Straight, minimally disturbed fibers improve stiffness, fatigue life, and overall structural efficiency versus traditional woven cloth.
• Rapid thickness build-up: Heavy 35.39oz (≈1200gsm) reinforcement reduces ply count in high-load regions such as spars, stringers, and beams.
• Stable & easy to handle: Light stitching stabilizes the bundle, simplifying cutting, placement, and layup while maintaining fiber alignment.
• Resin compatible: Works with polyester, vinyl ester, and epoxy resin systems for broad process flexibility.
• Hexcel reliability: Manufactured by Hexcel for consistent fiber distribution, dependable quality, and repeatable performance.

Typical uses

• Wind turbine spar caps, shear webs, and primary structural elements.
• Marine stringers, transoms, girders, and longitudinal stiffeners.
• Automotive and motorsport chassis rails, rocker panels, crash structures, and stiffening members.
• Industrial beams, poles, ladders, profiles, and load-bearing composite structures.
• Hybrid laminates with biaxial/triaxial fabrics or woven cloth to tailor off-axis and impact performance.

Processing notes

• Suitable for vacuum infusion, VARTM, RTM, pultrusion, and wet layup processes.
• Maintain fiber alignment during cutting and placement to preserve unidirectional properties.
• Use appropriate flow media and infusion strategy to ensure full wet-out in heavy UD sections.
• Pair with multiaxial or woven reinforcements where additional transverse, shear, or impact strength is required.
• Follow resin supplier cure schedules; apply UV-stable coatings for parts exposed to sunlight.

Ordering

• Standard width: 49" (124cm)
• Sold by: Linear Yard — 1 yard = 36" length × full width.
• Continuous lengths: Multiple yards are supplied as one continuous piece whenever possible.

We sell this fabric by the linear yard. You will receive a continuous piece of fabric at the width listed.

For example, if the fabric is 50" wide, a quantity of 1 (linear yard) equals a continuous piece measuring 50" wide × 36" long. A quantity of 5 (linear yards) equals a continuous piece measuring 50" wide × 180" long.
