UV / Weathering ResistanceExcellent95/100
Chemical Resistance SummaryFiber is inert to most acids, alkalis, solvents and fuels at room temperature; attacked by strong oxidizers (hot conc. nitric, chromic acid, hypochlorite) and oxidized in air above ~400 °C. In service, chemical durability of a part is set by the resin matrix and by galvanic isolation from aluminium/steel fasteners.

Working with T1000GB-24K

Is T1000G easy to machine?

Extremely abrasive — use PCD or diamond-coated tools, high speed/low feed, dust extraction, and compression routers or waterjet to avoid delamination and fiber pull-out.

Can T1000G be welded?

Not weldable; joints are made by co-cure, adhesive bonding (peel-ply or plasma-prepared surfaces) or bolted metal fittings with galvanic isolation.

Can T1000G be formed, bent or molded?

Processed as prepreg autoclave/oven cure, wet or towpreg filament winding, RTM/infusion or AFP; keep low tow tension and generous fiber radii — the high-strength fiber is notch- and abrasion-sensitive during handling.

What surface finishes work on T1000G?

Surface is sealed with a resin-rich peel-ply or clear-coat/UV-blocking topcoat; never anodize or plate directly, and isolate from aluminium/steel with glass-ply or sealant to prevent galvanic corrosion.

T1000GB-24K — frequently asked

What is T1000GB-24K used for?

T1000GB-24K is typically used for rocket motor cases, advanced military aircraft and high-end sporting goods. In short: highest tensile strength PAN fiber; filament-winding strength benchmark; highest cost, limited supply.

What is the tensile strength of T1000GB-24K?

T1000GB-24K has a typical tensile strength of 6,370 MPa (924 ksi) — stronger than 100% of composite grades. Strength varies by condition: see the 4 listed tempers.

Is T1000GB-24K easy to machine?

Not especially — machinability is rated poor (15/100, worse than 84% of composite grades). Extremely abrasive — use PCD or diamond-coated tools, high speed/low feed, dust extraction, and compression routers or waterjet to avoid delamination and fiber pull-out.

Can T1000GB-24K be welded?

What is the maximum service temperature of T1000GB-24K?

T1000GB-24K is rated for continuous use to about 400°C (752 °F), and briefly to 500°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
