Abstract
A ballistic composite laminate exemplified by a panel incorporating resin impregnated, heat and pressure bonded, fabric layers of high tensile strength "S" glass roving filaments on its backside extending through approximately one-half its thickness with the remainder of its thickness on the face side of the laminate formed of appreciably lower cost fabric layers of "E" glass filaments, which meet acceptance according to military ballistic acceptance tests substantially matching higher cost panels reinforced with fabrics of 100% "S" glass filaments.
Claims15
A ballistic impact resistant laminate structure comprising stacked layers of glass filament fabrics,
- said layers of glass fabrics each having been impregnated with heat curable resin bonding material,
- said stacked layers of impregnated fabrics having been integrated under heat and pressure to produce said structure,
- a portion of the thickness of said structure comprising fabrics of "E" glass roving filaments to provide a front face for said structure, and
- the remainder backside portion of the thickness of said structure comprising fabrics of "S" glass roving filaments.
A ballistic impact resistant structure, comprising a laminate formed of fabrics of glass reinforcement filaments impregnated with heat curable resin binder material integrated under heat and pressure,
- 40% to 60% of the thickness of said laminate including S glass filament fabrics on its backside,
- the remainder of the thickness of said laminate comprising E glass filament fabrics on its face side.
