CFRP AS4/3501-6 Quasi-Isotropic
Verifiedcomposite· AS4/3501-6· AS4 QI laminate
AS4/3501-6 quasi-isotropic CFRP is a carbon fiber reinforced epoxy composite with balanced fiber orientation (0°, ±45°, and 90°) designed to provide uniform stiffness and strength in multiple load directions. The layup consists of eight plies of Hexcel AS4 carbon fiber in a 3501-6 epoxy matrix, processed via autoclave prepreg curing, creating a material suitable for applications requiring multidirectional load resistance without a dominant stress direction. This quasi-isotropic architecture makes it a go-to choice over unidirectional or angle-ply laminates when loading conditions are complex or unpredictable, though engineers sacrifice peak performance in any single direction compared to tailored layups.

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.
