Security Glass

A Security Glass is a transparent composite material designed to avoid penetration of hard objects intending to pass from one side to the other, more specifically projectiles intended to cause harm to people on the second side. It is normally composed of several layers of glass, polymers or other transparent materials bonded together by a process involving temperature and pressure.  Its total thickness and composition can vary a lot depending on the specific threat for which it has been designed.

NIJ 0108.01 - USA NORM

NIJ 0108.01 - USA NORM

The National Institute of Justice (NIJ), an agency of the United States Department of Justice, along with the National Bureau of Standards defined this standard with the purpose to establish minimum performance requirements and methods of test for ballistic resistant protective materials, including BRG.
The figure above shows the array of impacts required for levels I to III.

CEN 1063 - EUROPEAN NORM

Perfect optics is the target of a good BRG. Optics is a matter of physics: when light goes from one transparent material to another part of it is refracted, part is reflected and other part may be absorbed. Balancing that right may be relatively simple in a single layer part; however, it is very complex in a curved multi-layer part. An uncontrolled mixture of reflection, refraction and absorption may result in several defects such as distortion, double image, poor light transmission, color modification etc.

High Standards

High Standards

AGP checks light transmission in each of its compositions as design parameter. Distortion and double image are inspected in the final product according to R43 international standard with either a last generation automatic equipment or a manual process and calculation, depending on the product and production plant. In both cases the process consists in placing the BRG part in the same angle as it will be installed in the vehicle, projecting light to pass through it and measuring the deviation of the projected light.

DURABILITY

DE - LAMINATION

DE - LAMINATION

Is the process of separation between adjacent material surfaces. It is normally caused by poor adhesive force between the surfaces, the degradation of that force or excessive loads working to detach the surfaces. This is probably the most critical defect in BRG. As a composite material formed by many interfaces this separation can happen in different locations within the part and may have different characteristics and root causes.
AGP is permanently testing its compositions under different accelerated ageing standards to replicate the defect, identify the root causes and implement preventive actions

EXTERNAL CONDITIONS

EXTERNAL CONDITIONS

BRG durability is arguably (after safety), the second biggest concern of armored vehicle users and armored vehicle producers. As a composite material involving several different materials and boundary conditions BRG may be subject to a number of defects which are evident only after relatively long operation time. AGP concentrates large efforts and resources to replicate durability defects in accelerated ageing tests, identifying the root causes and implementing preventive actions to ensure that AGP BRG has the best long term performance in the market. Many BRG defects can appear with time...

ABRASION

ABRASION

Is the process of scratching or wearing down a surface, it can happen in both the inner or the outer surface of the BRG and is normally caused by the friction of the surface with harder objects or particles. BRG external surface is normally glass, a very hard material, even though it can be scratched; therefore AGP is always exploring the use of harder materials or hardening processes.
Inner surface is even more critical because it is normally a plastic material; in this surface AGP uses PC Hi-Tech, which is approximately 33% more resistant to abrasion than standard PC according to ASTM D1044.

CHEMICAL ATTACK

CHEMICAL ATTACK

Is the process of degradation of certain material caused by its interaction with chemical components of other material. It is a common defect in BRG as several of the materials normally used (mainly plastics) may be affected by chemical components frequently present in commercial cleaning and bonding products.
To avoid chemical attack AGP uses materials with good chemical resistance to most commercial products in the outer surfaces, such as PC Hi - Tech; however, specific (application related) testing of the material is strongly recommended.

PRODUCT DEVELOPMENT - REVERSE ENGINEERING

PRODUCT DEVELOPMENT - REVERSE ENGINEERING

AGP’s APQP product development of BRG can be performed in two different ways, according to each customer requirements:

Reverse Engineering product development: when no CAD data is available, as for many of the vehicles armored each year in the retrofit market. In this case the surface geometry is taken and digitalized from the original glasses and the design is optimized by our technical experts in close coordination with the armoring partners.

PRODUCT DEVELOPMENT - CAD / CATIA

PRODUCT DEVELOPMENT - CAD / CATIA

3D CAD based product development: when the CAD data is availab le, as for an armored OEM vehicle. In this case most of the development is done digitally using CATIA V5 generating all CNC files ready to validate in a prototypes stage.

PRODUCT VALIDATION

PRODUCT VALIDATION

In all cases final product validation is done by prototype installation and verification together with a partner. A live Design Failure Modes and Effects Analysis (DFMEA) is used to compile and avoid main modes of failure. From here on the geometry of each part is verified with a physical gage.

SPECIFIC PRODUCT DEVELOPMENT PROCESS

SPECIFIC PRODUCT DEVELOPMENT PROCESS

A standardized and controlled production process is critical for ensuring BRG’s quality; the perfect ballistic composition with the perfect geometry development is of no use with an uncontrolled production process. AGP means to assure its production process include the following:
Controlled process flow. | Standard operating procedures (SOP) for 100% of the processes. | Live Process Failure Mode and Effects Analysis (PFMEA). | Control Plan for all Critical Characteristics. | Tooling and Instruments Control Plan ensuring inspection and calibration. | Preventive Maintenance Control Plan. | Production Planning and Control System.

STANDARDIZATION

STANDARDIZATION

BRG quality is determined by 4 items: ballistic composition design (ballistic formula), raw materials quality, perfect specific vehicle geometry development and production process assurance. Failure to achieve excellence in all four items may result in ballistic risks, optical defects or poor durability. AGP follows an Advanced Product Quality Planning process (APQP) to guaranty the quality of its BRG from the project planning to validation and production.

RAW MATERIAL

RAW MATERIAL

AGP has established solid long term partnerships with the worldwide leaders in the development and production of each of the raw materials commonly used in its products and works together with them since the product development stage. The results of this partnership are exhaustive Material Validation and Reception Control Plans.
Each time a new reference of a specific material is to be used in an AGP composition all the tests in the Validation Plan are executed. When a lot of raw material is to be shipped to AGP, a Quality Certificate is issued by the supplier and complemented by the execution of the Control Plan tests when it arrives to the AGP production facility. All the information is recorded and linked to the production orders so it is possible to track exactly which material, supplier and lot was used for each AGP BRG.
