Lightweight blast mitigating composite panel

摘要

Lightweight blast mitigating composite panels (10) include a first glass composite shell (14; 152), an intermediate, preferably honeycomb layer (56; 156), a reinforcing layer (60; 160), an ultra high molecular weight polyethylene fiber (UHMWPE) layer (64; 164) and a second glass composite shell (15; 168) adhered together with fire resistant adhesive layers (54; 58, 63, 66; 154, 158, 163, 166). The UHMWPE layer (64; 164) includes top and bottom coatings (70, 71) of fire resistant thermoset plastic preferably in the form of a paste. The panels (10) have use in a wide range of applications including in a blast mitigating overhead storage bin (100). The storage bin (100) includes a main body portion (133) defining a storage area formed from composite unarmored and armored panel segments (137, 138; 128-132). The unarmored and armored panel segments (137, 138; 128-132) share first and second shells (14, 15) to form an integral main body portion, with the armored panel segments (128-132) providing blast protection between the storage area and a wall (125) of an airplane cabin (120).

主权项

1. A lightweight blast mitigating composite panel comprising:
a first glass composite shell; an intermediate layer; a first flame resistant adhesive layer interposed between and adhering the intermediate layer to the first glass composite shell; a first reinforcing layer; a second flame resistant adhesive layer interposed between and adhering the first reinforcing layer to the intermediate layer; an ultra high molecular weight polyethylene fiber layer including an upper coating of fire resistant thermoset plastic and a lower coating of fire resistant thermoset plastic; a third flame resistant adhesive layer interposed between and adhering the ultra high molecular weight polyethylene fiber layer to the first reinforcing layer; a second glass composite shell; and a fourth flame resistant adhesive layer interposed between and adhering the ultra high molecular weight polyethylene fiber layer to the second glass composite shell.
