IM7/8552 [90]₈

Verifiedcomposite

IM7/8552 is a carbon fiber reinforced polymer (CFRP) composite featuring IM7 carbon fibers in an 8552 epoxy resin matrix, with a quasi-isotropic layup configuration ([90]₈ denoting eight plies oriented at 90°). This material system is widely used in aerospace and defense applications where high specific strength, stiffness, and environmental resistance are critical, particularly in primary structures that experience moderate to high service temperatures. IM7/8552 is favored over lower-performance alternatives for applications demanding superior fatigue resistance, dimensional stability, and damage tolerance, making it a standard choice in commercial and military aircraft, satellites, and advanced composites where weight reduction and structural reliability directly impact 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.
