Method & Evidence

AimTo investigate the impact response and perforation thresholds of composite plates manufactured with different configurations of stitch-bonded non-crimp glass fiber fabrics (biaxial, triaxial, and quadraxial) using a polyester resin matrix.

MethodExperimental testing

ProcedureComposite plates were fabricated using polyester resin and three types of glass fiber fabrics (biaxial, triaxial, quadraxial). Instrumented drop weight impact tests were conducted at various impact energies. Load-deflection curves and energy absorption profiles were analyzed to determine penetration and perforation thresholds. Damaged specimens were visually inspected to evaluate failure modes.

ContextComposite material manufacturing and impact testing

Variables

IVType of glass fiber fabric (biaxial, triaxial, quadraxial)

DVPerforation threshold energy, absorbed energy, load-deflection characteristics

CVMatrix material (polyester resin), composite plate thickness, impactor mass and shape, testing machine parameters

Strengths & Limitations

Strengths

+Direct experimental measurement of impact response.
+Comparison of distinct fiber architectures within the same matrix system.

Limitations

The specific resin and fiber types used might not be representative of all composites. The study did not explore the long-term effects of impact or fatigue.

Reliability & validity

The use of an instrumented drop weight impact testing machine and standardized procedures enhances the reliability of the impact data. Validity is supported by the clear differentiation in performance between the tested material configurations.

Think critically

How might the cost and manufacturing complexity of triaxial composites compare to biaxial or quadraxial options, and how would this influence their adoption in different market segments?

Design Principles

"Fiber architecture in composite materials directly correlates with impact performance, with multi-directional weaves offering improved resistance to penetration."

Understanding the impact response of composite materials is crucial for designing products that can withstand accidental impacts, such as in automotive, aerospace, or sporting goods applications. This knowledge allows for material selection and structural optimization to enhance safety and durability.

What This Means for Your Design

Using a triaxial weave of glass fibers in a composite makes it much harder to punch through compared to biaxial or quadraxial weaves.
