CFRP M55J/RS-3C Ultra-High Modulus

· M55J/RS-3C· UHM CFRP

CFRP M55J/RS-3C is an ultra-high modulus carbon fiber reinforced polymer combining Toray's M55J carbon fiber with TenCate's cyanate ester matrix, processed via autoclave prepreg for 0° unidirectional layup. This material targets aerospace and space structures where exceptional stiffness-to-weight ratio and dimensional stability under thermal cycling are critical performance drivers. The combination of ultra-high modulus fiber with a high-temperature thermoset matrix makes it suitable for demanding applications that require minimal deflection, superior creep resistance, and reliable performance in extended temperature environments—distinguishing it from general-purpose epoxy composites used in less stringent load cases.

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.
