... depth can be measured. Carbon/epoxy composite materials have a characteristic wave speed of approximately 3.2 mm/μs (0.125 in./µs). This can vary by as much as 5% in parts of the same material, so care must be used when using PE ultrasound for absolute thickness measurements. Automated PE inspection...

...-fiber-reinforced composites offer a specific modulus approximately twice that of steel or aluminum. Comparing efficiently designed structural elements, the fatigue endurance limit for aramid and carbon-fiber-reinforced epoxies may approach 60% of the ultimate tensile strength. For aluminum and steel...

The polyester fibers of an apertured veil are woven in such a manner that a pattern of small squares is formed through the veil. Carbon veil also provides excellent resistance to caustic and hydrofluoric acid...

Surface treatments, which increase the number of active chemical groups and sometimes roughen the fiber surface, have been developed for the more mature resin matrix composites. Carbon fibers are commonly shipped with an epoxy size, which usually prevents fiber abrasion, improves...

... TPCs. Carbon-polyetheretherketone (PEEK) composites were successfully assembled and repaired by both techniques, although both had some disadvantages. Adhesive bonding required an appropriate surface treatment, but the relatively low temperatures involved (180 °C, or 355 °F) minimized the risk of...

Carbon fibers offer a range of properties, including an elastic modulus up to 966 GPa (140 psi × 10 6 ) and a negative CTE down to −1.62 × 10 −6 /°C (−0.9 × 10 −6 /°F). However, carbon and aluminum in combination are difficult materials to process into a composite. A...
