Boston Materials produces Carbon Supercomposites, a 3-dimensionally reinforced line of carbon fiber materials. We align discontinuous milled fibers in the z-direction of industry-standard carbon fiber weaves. These milled fibers fill the interstitials of biaxial weaves to create through-thickness reinforcement, as well as coat the material to provide interlaminar reinforcement between adjacent plies.
One important feature of Carbon Supercomposites is that they come in an industry-standard roll of either dry fabric or prepreg. The plies can be cut into customized shapes and are compatible with standard wet and prepreg layup processes as well as RTM.
- Understand the impact and benefits of z-axis reinforcement in composite materials
- Recognize applications where z-axis fibers are a necessity
- Integrate Carbon Supercomposites into existing and upcoming component designs
Why Is This Important?
Carbon fiber composites were developed in the 1970s and promised better performance than metals at fraction of the weight. Over the last 40 years, composite materials have been implemented by virtually all manufacturers in the aerospace, defense, transportation, and energy sectors but have failed to phase out many bulky metal-based designs.
Carbon fiber composites fail by delamination (peeling apart) caused by lack of through-thickness performance – problems that metals do not have. These two issues are preventing the full adoption of carbon fiber composites and the phase-out of bulky metals. The design of current- and next-generation products with increased energy efficiency and decreased raw materials usage relies on the development of a carbon fiber composite that addresses the issues of delamination and poor through-thickness performance.
OEMs and tiered suppliers of wind turbine, aircraft, satellite, automobile, and energy storage products are all struggling to fully implement composite structures and eliminate metal designs. A material that bridges the performance gap between metals and carbon fiber composites is needed to improve current-gen products and enable next-gen solutions.
