· T800H/3900-2· Toray 3900-2

CFRP T800H/3900-2 is a high-performance unidirectional carbon fiber reinforced polymer combining Toray's T800H intermediate-modulus carbon fiber with a toughened epoxy matrix, processed via autoclave prepreg for consistent fiber alignment and minimal voids. It is used in aerospace primary structures (wings, fuselages), high-speed rotorcraft, and demanding defense applications where the combination of stiffness, strength, and impact resistance enables weight reduction without sacrificing damage tolerance. Engineers select this material over standard T700 or IM7 systems when the superior fiber properties and toughened matrix justify the cost—particularly in load-critical components that experience transverse loads, vibration, or require excellent fatigue performance.

Quality & Standards

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
