ACCC^® Composite Core

CTC Global’s ACCC® Composite Core consists of high-strength carbon and glass fibers embedded in a toughened thermoset epoxy resin matrix. The composite core is manufactured to aerospace quality specifications using a continuous pultrusion process developed by highly skilled pultrusion experts. The ACCC® Conductor’s composite core offers a strength to weight ratio approximately six times better than steel, with a coefficient of thermal expansion about ten times lower. The composite core is also impervious to corrosion and cyclic load fatigue. CTC Global’s ACCC^® Conductor cores are currently available in 310 and 375 ksi tensile strengths. The higher strength version – referred to as ULS – also offers a higher modulus to accommodate longer spans and extreme ice loads. For comparison, extra high strength steel is rated at 285 ksi, but is approximately 70 percent heavier than the ACCC® Composite Core.
