Hand Lay-up
An open mold process in which components or successive plies of reinforcing material or resin-impregnated reinforcements are applied to the mold, and the composite is built up and worked by hand.

Emerging Applications of Ceramic and Metal...
Many of the 500 papers presented during the 27th Annual Cocoa Beach Conference & Exposition on Advanced Ceramics & Composites focused on composites, both ceramic and metal matrix, and discussed mechanical behavior, design, fibers/interfaces, processing, and applications. Potential applications under development include components for armor, nuclear energy, and automobiles.
