Working with HTS40 UD-EP60
Is HTS40 easy to machine?
After cure, use PCD or diamond-coated tooling and diamond wheels at high speed and small feed with dust extraction to avoid delamination and burrs. The dust is conductive, so guard against short circuits and use spark-safe collection.
Can HTS40 be welded?
Not weldable; join by adhesive bonding or mechanical fasteners. Use titanium or stainless fasteners with an isolating layer to prevent galvanic corrosion.
Can HTS40 be formed, bent or molded?
Suits wet and dry filament winding, pultrusion, RTM, braiding and autoclave-cured prepreg. F13 and E13 sizings wet out well in epoxy; thermoplastic matrices require a matrix-specific sizing.
What surface finishes work on HTS40?
Weave texture is normally covered with a topcoat or gel coat. Sand wet to control dust, and add a UV-blocking coating on exposed parts to protect the resin rather than the fiber.
HTS40 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

HTS40 UD-EP60 — frequently asked
What is HTS40 UD-EP60 used for?
HTS40 UD-EP60 is typically used for automotive structural parts, wind energy, sporting goods and industrial tooling. In short: T700-class high tenacity; industrial-volume standard modulus; wide sizing and tow range.
What is the tensile strength of HTS40 UD-EP60?
HTS40 UD-EP60 has a typical tensile strength of 2,400 MPa (348 ksi) — stronger than 78% of composite grades. Strength varies by condition: see the 5 listed tempers.
Is HTS40 UD-EP60 easy to machine?
Not especially — machinability is rated poor (25/100, worse than 65% of composite grades). After cure, use PCD or diamond-coated tooling and diamond wheels at high speed and small feed with dust extraction to avoid delamination and burrs. The dust is conductive, so guard against short circuits and use spark-safe collection.
