· As4 C3

AS4 C3 is a carbon fiber reinforced composite material, where AS4 refers to a high-strength polyacrylonitrile (PAN)-based carbon fiber commonly used as reinforcement in advanced composites. The C3 designation typically indicates a specific resin matrix system or fiber treatment specification, though without detailed composition data, the exact resin type cannot be confirmed. This material class is widely deployed in aerospace structures, sporting equipment, and high-performance automotive applications where the combination of carbon fiber strength and matrix properties enables lightweight, fatigue-resistant designs that outperform aluminum and steel alternatives in critical load paths.

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.
