Abstract

The invention discloses a composite explosion-proof board capable of shielding high speed broken sheets and high strength blasting impact. The composite explosion-proof board capable of shielding highspeed broken sheets and high strength blasting impact comprises a broken sheet damage layer, a buffer dispersion layer, and a structure support layer; the broken sheet damage layer is prepared from high strength constructional steel; the buffer dispersion layer is prepared from ultra high molecular polyethylene fiber; the structure support layer is composed of glass fiber and an epoxy composite material; the broken sheet damage layer, the buffer dispersion layer, and the structure support layer are laminated successively, and are bound using an epoxy adhesive. The structure is simple; the cost is low; manufacturing is convenient; shielding performance on high speed broken sheets and high strength blasting impact is excellent; and the composite explosion-proof board is an excellent explosion-proof material.

Description

Technical field

[0001] The invention relates to a composite explosion-proof plate capable of resisting the impact of high-speed fragments and high-strength explosions and a manufacturing method, and relates to a composite explosion-proof plate capable of protecting against ultra-high-strength explosion shock waves (≀0.15MPa) and ultra-high-speed fragment damage (≀1700m / s) Plate and manufacturing method. Background technique

[0002] Field combat training and field testing of missile forces are routine and necessary training items. During the training process, personnel, equipment, and related materials in designated areas need to be protected. Traditional board protection materials include steel plates, sand, concrete, etc., but a single material has different degrees of "short board" in terms of usability. For example: steel plate is heat-resistant but not fire-resistant, and has poor corrosion resistance; the amount of sand needed to resist the impact of high-strength explosio...
