Bullet-resistant fiberglass panels function as structural composites engineered to absorb and contain ballistic energy under defined threat conditions. Their performance is not determined by a single material property, but by the interaction of fiber quality, resin compatibility, layer sequencing, and curing precision. At Armortex, these variables are controlled within a vertically integrated manufacturing environment that begins with in-house fiberglass weaving and progresses through calibrated lamination and consolidation before concluding with UL 752 validation. By overseeing each stage internally, we reduce variability, strengthen traceability, and ensure that every bullet-resistant fiberglass panel delivers documented, repeatable ballistic performance.
Step 1: Manufacturing the Foundation Through In-House Woven Roving
The structural behavior of a bullet-resistant fiberglass panel is determined first through its reinforcement. Fiber architecture governs how force moves through the laminate and how energy is distributed across the composite. Rather than sourcing fiberglass fabric from external suppliers, Armortex manufactures woven roving in-house. Controlling reinforcement production at its origin allows us to regulate material consistency before lamination begins and eliminate variability that could compromise structural integrity.
With reinforcement production controlled at the source, woven roving is formed from continuous glass filaments interlaced into a balanced, high-tensile fabric. The weave configuration distributes force across multiple axes, allowing impact energy to spread through the panel instead of concentrating at a single location. We verify that each batch meets defined structural specifications before it enters the lamination process by managing strand alignment, weave density, and fabric weight internally. This level of control establishes a uniform reinforcement structure that supports consistent energy distribution throughout the finished bullet-resistant fiberglass panel.
Step 2: Engineering the Resin Matrix and Saturation Process
Reinforcement defines the load-bearing framework of a bullet-resistant fiberglass panel, but the resin matrix determines how that framework behaves as a unified composite. The matrix binds individual glass filaments into a continuous structure, controlling how stress transfers between layers under impact. Armortex applies a proprietary thermoset polyester resin engineered for chemical and mechanical compatibility with the woven roving. Once cured, the polymer network secures every filament in position while enabling controlled stress redistribution across the laminate.
Equally important is saturation control. Resin must fully wet each fiber bundle without introducing voids or excess accumulation that can alter laminate density. Our automated impregnation systems maintain precise resin-to-glass ratios and remove entrapped air during consolidation. Since fiber production and resin application are managed within the same vertically integrated facility, material interaction is verified before curing begins. The cured laminate exhibits uniform density, stable mechanical properties, and consistent resistance to certified threat classifications.
Step 3: Strategic Layering for Defined Threat Levels
Bullet-resistant fiberglass panels are engineered to meet specific threat classifications under UL 752. Those levels determine ply count, fiber orientation, and total laminate thickness. Such structural variables are defined before production begins and carried through manufacturing without deviation within Armortex’s engineering process. Panel construction is therefore governed by certified UL 752 test criteria, ensuring the laminate configuration reflects documented threat classifications from design through production.
The configuration parameters of the bullet-resistant fiberglass panel determine how energy enters, transfers, and dissipates within the laminate structure. Ply count, orientation, and thickness establish the pathways through which energy travels once impact occurs. When a projectile contacts the surface of a bullet-resistant fiberglass panel, energy transfers progressively through successive plies. Variations in fiber orientation redirect stress pathways, while controlled interlaminar separation slows penetration and distributes load across a broader surface area. Progressive energy redistribution through the laminate limits localized stress concentration and enhances projectile containment. Standardized ply configuration and press parameters maintain consistent structural resistance across the full surface area, whether bullet-resistant fiberglass panels are manufactured in 3×8,9,10, or 4×8,9,10, the sizes which are available from Armortex.
Step 4: High-Pressure Consolidation and Thermal Curing
Following lamination, the composite assembly is transferred to hydraulic presses where controlled heat and pressure transform stacked layers into a unified bullet-resistant fiberglass panel. During consolidation, residual air is removed and the laminate is compacted to its engineered thickness. The thermoset curing reaction begins under these controlled conditions, forming a rigid polymer matrix that locks reinforcement layers into a stable structural system. Density, rigidity, and dimensional stability are established at this stage, directly influencing how the finished panel performs and installs in the field.
With consolidation complete, curing conditions are regulated using monitored temperature profiles, calibrated pressure application, and defined dwell times to achieve full polymerization without inducing internal stress. Proper consolidation produces bullet-resistant fiberglass panels that remain flat, dimensionally stable, and ready for integration behind drywall or architectural finishes. Prior to shipment, production batches undergo dimensional inspection and ballistic testing to verify compliance with UL 752 standards. Validation demonstrates that the engineered laminate configuration and controlled manufacturing process produce certified, measurable protection.
Control at Every Stage, Protection in Every Panel
Armortex’s manufacturing process is designed to deliver robust bullet-resistant fiberglass panels through controlled execution at each stage of production. Reinforcement architecture, resin saturation, strategic layering, and precision consolidation function together as an integrated system that defines how composite responds under specific threat conditions. Vertical integration and disciplined process control preserve structural consistency from raw materials through to final validation under UL 752. The result is a bullet-resistant fiberglass panel built with engineered integrity and verified resistance.
