Peggy Malnati Contributing Writer

Peggy Malnati is a Detroit-based contributing writer for CompositesWorld magazine since 2006, for which she primarily covers automotive and ground transportation.

A long-time member of SAE and SPE, she has organized and managed large technical sessions and conferences for both organizations as well as for the former Structural Plastics division of SPI. For 15 years, she was a board member and the communications chair for the SPE Automotive Division. She also was editor of the 1994 McGraw-Hill book Structural Analysis of Thermoplastic Components. She has provided writing and communications services for the global plastics and composites industries since 1984.
