Blast Resistant Fiber Cement Composite Panel

The overall structural design of the panel follows the concept of "ductile outer layer + energy-absorbing inner core", with no bonding gap or hollow layer in the whole plate body, solving the common defects of delamination, peeling and low impact resistance of ordinary composite boards：

The outer protective layer on both sides is made of high-quality hot-dip galvanized steel sheet with precise uniform perforation technology. The regular hole array on the steel surface is not a simple decorative design, but a key structural innovation for composite integration. In the high-temperature and high-pressure autoclave production process, the high-density fiber cement base material fully penetrates the steel plate holes and forms a firm mechanical occlusion structure with the metal layer. This physical interlocking mode completely replaces traditional glue bonding, ensuring that the steel layer and the cement core will not separate under strong impact, high temperature aging or long-term damp environment, and greatly improving the overall structural stability and service life of the panel;
The middle core layer is the core functional area for anti-blast and fire resistance, which is made of low-alkali high-strength cement, alkali-resistant glass fiber, natural cellulose fiber and inert mineral aggregate through scientific proportioning. After long-term autoclave curing and constant-temperature aging treatment, the internal fiber forms a crisscross three-dimensional network structure. Compared with ordinary brittle cement boards, this fiber-reinforced core has excellent toughness and energy absorption characteristics. When the panel is subjected to instantaneous explosion shock wave pressure, the internal fiber network can quickly disperse local concentrated stress, convert violent impact kinetic energy into micro-deformation energy of the plate body, and realize layered attenuation of explosion energy. It avoids the overall fragmentation and instantaneous collapse of the wall panel, and fundamentally eliminates secondary injury risks caused by broken plate splashing after explosion

In terms of safety performance mechanism, this anti-blast composite panel has dual protection capabilities of explosion resistance and fire resistance. For accidental deflagration and explosion impact in industrial workshops, the outer galvanized steel sheet firstly bears and evenly disperses the instantaneous shock wave, blocking high-speed flying debris from penetrating the partition wall. The inner fiber cement core further consumes residual explosion energy through micro-structure deformation, ensuring that the wall body remains intact and stable after bearing the specified explosion load. In terms of fire protection, the whole panel is made of fully inorganic non-combustible materials, without any flammable organic additives. It can maintain structural integrity for a long time under high-temperature flame baking, effectively blocking flame spread and hot gas transmission, and the fire resistance limit of single-layer installation can reach 4 hours, which meets the highest fire protection standards of most industrial buildings in Europe, Southeast Asia, the Middle East and other regions;

In addition to core safety performance, the panel's physical stability is also optimized for harsh industrial environments. The integrated compact structure has excellent moisture-proof, mildew-proof and anti-aging properties. The galvanized steel layer isolates external water vapor and humid air, and the inorganic cement core will not expand, deform or mildew in long-term damp, high-temperature and ventilated industrial environments. The product has no asbestos and harmful substances, fully complying with global environmental protection and building material safety certification requirements. All production links adopt closed-loop quality inspection, including raw material screening, perforation precision detection, composite pressing uniformity test and finished flatness calibration. Each batch of products can provide professional third-party test reports to support engineering acceptance and project certification;

In engineering application, the panel supports dry construction installation, which can be quickly cut and assembled on-site according to project size requirements, matched with standardized steel frame keel structure, without wet cement pouring and long curing cycle. It greatly improves the construction efficiency of anti-blast partition walls, ceilings and equipment protective enclosures. For architectural designers and engineering technical engineers, this standardized structural panel with stable performance parameters can be flexibly integrated into various industrial safety design schemes, providing a lightweight, high-strength and high-reliability passive safety protection solution for modern high-risk industrial buildings
