Infused, fiberglass/polyester composite boat hulls have been built since the mid-1900s, expanding over time to include additional resins and foam cores. Composites continue to be a mainstay for various types of boats and luxury and racing yachts, and now include newer innovations such as carbon fiber precision hydrofoils and recycled carbon fiber or bio-based resins.

Boston Materials uses milled reclaimed carbon fibers to increase modulus, impact/delamination resistance and produce metals-like conductivity for EMI shielding, lightning strike protection, heat exchangers and more.

Designed for room-temp infusion and filament winding with 2-hr no-heat-added cure or 15-30 min heated cure without post-cure for flexible processing of marine, industrial and energy structures.

The composites show’s appearance in Paris this spring promises to be bigger than ever before, reflecting the industry’s post-recession resurgence.

Scott M. Lewit, CCT, holds an MS in ocean engineering from the Florida Institute of Technology (1985). Lewit is president and founding partner of Structural Composites Inc. and COMPSYS Inc., the managing director of the Navy CCT Marine Composites Technology Center, and a co-inventor of the resin recirculation

In Part I of a series about the past, present and future of training in marine composites, Andre Cocquyt outlines the historical difficulty composites manufacturers have had in finding qualified technicians, and how that reality led to his involvement in the development of training programs.

Physical and virtual material libraries and access to designers should attract composites industry participation.

An intelligent, integrated process using 3D fiber spraying, inline inspections/simulation and embedded RFID chips to cut scrap and rejections for structural HP-RTM epoxy parts.

The hull mirror-like gel coat finish on the Daedulus 30 cabin cruiser was achieved through a combination of Marine Concepts’ (Lee-on-the-Solent, Hampshire, U.K.) mold design experience and fabrication techniques and materials provided by Scott Bader (Wollaston, Northamptonshire, U.K.).

For most of the last several decades, whenever someone used the words “composites” and “boats” in the same sentence, it’s likely that you immediately thought “fiberglass.” And rightfully so.

Ray Tsai, technical director of Simutech Solution Corp. (Taipei, Taiwan) and colleagues develop a demonstration modeling exercise for Taiwanese motoryacht builders.
