Lightweight Reading: Endless Summer Edition

Welcome to another installment of Lightweight Reading, CWs semi-regular blog post rounding up some of the fun and sometimes unusual product releases and news within the composites industry. As summer draws to a close, I thought it might be fun to reflect on a couple of recent water sport products that feature composites.

Composite materials and innovations are constantly evolving. In addition to industry news, features, blog posts and podcasts, CW also maintains a comprehensive collection of product announcements provided by companies. This monthly roundup includes links to regular posts concerning the latest products of interest to the composites industry.

This month’s innovations include:

Like many people, this week past I’ve been obsessed with NASA’s solar probe. The Parker Solar Probe — named after solar science pioneer Professor Eugene Parker who developed theories on solar wind and the solar magnetic field in the mid-1950s — launched on Aug. 12 and will travel to the corona of the Sun to study the star and solar wind.

The probe will perform in situ measurements and imaging to study the corona. In order to endure the extreme temperatures in this region which reach approximately 2,500°F (1,377°C), the probe utilizes a 4.5-inch thick lightweight reflective shield. This Thermal Protection System (TPS) is made from carbon composite foam sandwiched between two carbon plates and coated with white ceramic paint on the sun-facing surface. The shield was designed by Johns Hopkins Applied Physics Laboratory (Laurel, Maryland, US) and built at Carbon-Carbon Advanced Technologies (Kennedale, TX, US).

My April blog “Continuous fiber thermoplastics are smart for world’s largest appliance manufacturer” discussed the development of a high-end production air conditioner using CFRTP composite materials by supplier Covestro and the world’s largest appliance company Haier. Now Covestro has trademarked these materials as Maezio, which include carbon or glass fibers impregnated with polycarbonate (PC), thermoplastic polyurethane (TPU) or other thermoplastic resins. Covestro produces unidirectional reinforced tapes and sheets at its production site in Markt Bibart, Germany.

It’s long overdue. After nearly 20 years of CW coverage about composites for infrastructure — in bridges, concrete formwork, piping, electrical transmission towers, and more — our government has taken notice of composites for streamlining and ultimately saving money on all aspects of infrastructure projects, thanks in large part to the persistent efforts of the American Composites Manufacturers Association (ACMA). On August 2, ACMA announced that both chambers of Congress have introduced new legislation to encourage research and deployment of innovative construction techniques and materials in transportation and water infrastructure projects nationwide. According to Senator Sheldon Whitehouse’s (D-RI) web page, investing in these new techniques and materials would help to extend the life of critical public works that draw increasingly poor ratings for condition and performance.

The legislative bill, known as the Innovative Materials for America's Growth and Infrastructure Newly Expanded (or IMAGINE), was introduced in the Senate by Whitehouse, Lamar Alexander (R-TN), Mike Rounds (R-SD), and Cory Booker (D-NJ), and in the House of Representatives by Reps. Barbara Comstock (R-Va.), Elizabeth Esty (D-Conn.), and David Cicilline (D-R.I.). It is designed to promote the increased use of innovative materials like FRP composites, as well as new manufacturing methods to speed up the deployment and extend the life of infrastructure projects.
