· XP251S· Fiberglass/Epoxy

Glass fibre in an epoxy matrix. Glass/epoxy is the workhorse of secondary aircraft structure and tooling: far cheaper than carbon, electrically transparent, and tolerant of impact and handling damage. It is chosen where stiffness-per-pound is not the governing requirement — radomes and antenna windows, fairings and access panels, lay-up tooling, and marine and industrial laminates. The handbook characterises it from -65 °F to 350 °F, consistent with elevated-temperature service. MatWorld carries 108 tensile, compressive and shear curves for this system, digitised from MIL-HDBK-17-2F Volume 2 (US Government work, public domain).

Quality & Standards

Industry-Specific

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.
