Résumé :
Polymer Matrix Wave-Transparent Composites

One-stop reference on important recent research accomplishments in the field of polymer matrix wave-transparent composites

Polymer Matrix Wave-Transparent Composites: Materials, Properties, and Applications is a unique book that focuses on polymer matrix wave-transparent composites for electromagnetic wave transmission of a certain frequency, discussing various aspects of design, fabrication, structure, properties, measurement methods, and mechanisms, along with practical applications of functional polymer composites in industrial fields ranging from aircraft radomes, to radomes for ground, shipborne, and airborne purposes, to radomes for 5G communication, to printed circuit boards and beyond.

Edited by four highly qualified academics and contributed to by well-known experts in the field, Polymer Matrix Wave-Transparent Composites includes detailed discussion on sample topics such as:

• Interface between the reinforced fiber and polymer matrix, including basic concepts, characterization, and the most common method of functionalization for the interface
• Mechanism of wave-transparent, factors that influence wave-transparent performance, and fabrication techniques
• Processes of hand paste molding, pressure bag molding, laminated molding, resin transfer molding (RTM), and winding molding
• Physical and chemical properties of the inorganic fibers (glass fibers and quartz fibers) and organic fibers (aramid fibers, ultra-high molecular weight polyethylene fibers and poly-p-phenylene benzobisoxazole fibers)

Polymer Matrix Wave-Transparent Composites is an essential reference on the latest research in the field for researchers and related professionals, as well as for individuals who are not familiar with the field and wish to gain a holistic understanding in one place....
