AS4/3502 Plain Weave Fabric (MIL-HDBK-17)
Verifiedcomposite· AS4/3502 PW· 3502 Fabric
AS4/3502 is a carbon fiber reinforced epoxy composite in plain weave fabric form, combining Hexcel's AS4 carbon fiber (3K tow) with 3502 epoxy matrix, cured via autoclave prepreg processing. This material is a workhorse in aerospace and defense, selected for primary and secondary structures where balanced in-plane properties, damage tolerance, and manufacturing repeatability are required. The plain weave architecture (versus unidirectional or twill) provides good transverse strength and impact resistance with acceptable longitudinal performance, making it ideal when loads aren't purely directional or when lay-up flexibility and ease of handling outweigh ultimate performance density.

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.
