Book

Carbon fiber composites have become the core material of modern industry with their lightweight and high strength properties, but their complex orthogonal anisotropy, multi-angle layup and multi-layer structural properties pose great challenges for accurate strain measurement and calculation. Breaking through the traditional research framework, this book presents a set of methods for internal strain assessment of carbon fiber laminates based on experimental measurement techniques, injecting new perspectives into this field. By selecting carbon fiber laminate samples with different layup angles and thicknesses, this book systematically compares the synergistic application of traditional measurement tools such as tensiometers and strain gauges with HyperMesh finite element simulation, and accurately analyzes the distribution of strain in the main direction of internal layers. The high agreement between experimental data and simulation results not only verifies the reliability of the method, but also reveals the mechanical response mechanism of multilayer composites. The methodology proposed in the book provides a set of quantifiable and reproducible practical framework for the structural optimization design, performance evaluation and engineering application of composite materials.
