Composites Use in Military & Defense
One of the main drivers of composites use in defense-related structures – such as components for fighter jets and other aircraft, weapons systems, and to some extent land- and water-based vehicles – is the high temperatures and harsh conditions in which these applications are used. Composite materials also offer high impact resistance, light weight and corrosion resistance needed for work in the field.

How are composites used in the defense market?
Composites can be used to lightweight defense aircraft and other vehicles, increasing range or allowing higher payloads.
Ultra-high temperature (UHT) composite materials can also be tailored to withstand harsh environments and high temperatures, or to be antiballistic. Research and production of ultra-high temperature (UHT) ceramic matrix composites (CMC), with melting points of 2,500°C (4,532°F) or higher, has ebbed and flowed over the years, following rising and falling demand for applications like hypersonic defense systems and space launch vehicles.

Can composite materials be antiballistic?
New materials cntinue to be developed for use as bullet-proof armor for vehicles, infrastructure and equipment.
Historically, antiballistic material designers have preferred tough but expensive aramids, high-density polyethylenes and the like, passing over conventional E-glass as too brittle to have ballistic stopping power.
Proprietary additives and resin systems have enabled the development of bullet-proof fiberglass materials. 3D weaving of carbon fiber, fiberglass or other composite materials can also help to develop high-strength preforms for use as armor materials or molded panels.
