CFRP IM7/8552 Unidirectional
Verifiedcomposite· IM7/8552· Hexcel 8552
CFRP IM7/8552 is an autoclave-processed carbon fiber reinforced polymer composite combining Hexcel's high-strength IM7 carbon fibers with a toughened 8552 epoxy matrix, engineered as a unidirectional lamina for primary load-bearing applications. This material system is widely specified in aerospace structures—including aircraft fuselages, wings, and control surfaces—and increasingly adopted in high-performance sporting goods and industrial equipment where weight reduction, damage tolerance, and thermal stability are critical. The IM7/8552 combination is valued over competing systems for its balance of fiber stiffness, matrix fracture resistance, and processing robustness in demanding environments.

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.
