ABYC Composites Practice Exam 2025 – Complete Study Guide

Aramid fibers are a category of synthetic fibers known for their high strength and thermal stability, commonly used in applications requiring durability and resistance to heat. Kevlar is one of the most recognized examples of aramid fiber, renowned for its use in bulletproof vests, aerospace components, and various high-performance applications.

When discussing the other options, glass fiber is primarily made from silica and is commonly used in reinforcing composites but does not fall under the aramid fiber classification. Carbon fiber, while offering high strength-to-weight ratios and structural integrity, is distinct from aramid fibers as it is composed of carbon atoms arranged in long chains. Bagasse fiber, derived from the fibrous residue left after sugarcane processing, is organic and not synthetic, clearly separating it from aramid fibers.

Thus, Kevlar stands out as the prime example of aramid fiber, embodying the characteristic properties associated with this category of materials.
