Abstract: A safety helmet includes an outer shell configured for surrounding a head of a user, and an infrared reflective layer disposed in an interior of the outer shell. The infrared reflective layer is configured for reflecting at a least a portion of incident infrared radiation transmitted through the outer shell. The infrared reflective layer has infrared reflectivity of at least 40%. The safety helmet further may have an evaporative cooling pad positioned within a cavity defined by the inner surface of the outer shell. A method of manufacturing a safety helmet is also disclosed.

Abstract: A projectile resistant device for use in armor includes a ceramic component; and at least a first component adhered to the ceramic component on at least one side thereof. Preferably the first component is a woven carbon fabric that is adhered to the back surface of the ceramic component. The projectile resistant device can further include at least a second component adhered to the front surface of the ceramic component. The second component preferably comprises a woven carbon fabric. The projectile resistant device can also include a retention layer adhered to the front surface of the second component. At least a portion of the retention layer extends around the edges of the second component, the ceramic component, and the first component and is adhered to the back surface of the first component. Preferably the retention layer is a woven fiberglass.
