· IM7· Hexcel IM7· IM7 12K

IM7 is an intermediate-modulus polyacrylonitrile (PAN)-based carbon fiber produced by Hexcel, designed to balance stiffness and toughness in structural composites. It is widely used in aerospace primary structures, wind turbine blades, and high-performance sporting goods where weight savings and damage tolerance are critical; IM7 offers superior impact resistance and manufacturing ease compared to high-modulus fibers, making it the preferred choice for damage-tolerant design in commercial aircraft and large rotating machinery.

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.
