Abstract To investigate the mechanical response and failure mechanism of short carbon fiber reinforced polyether‐ether‐ketone (SCFR‐PEEK) composite under high‐velocity impact foreign bodies different shapes, experiments numerical simulations SCFR‐PEEK were carried out with blunt projectile, hemispherical ovoid projectile in velocity range 33.6 ~ 163.8 m/s. The results show that ballistic limit is highest lowest velocities studied. resistance better than projectile. has weakest at lower velocities, it rather higher velocities. damage morphology change trend target plate impacts warheads are different. In addition, use Extended Drucker‐Prager models can accurately describe behavior impact. corroborate each other, revealing influence laws shape warhead on plate. Highlights T700 fiber‐reinforced PEEK thermoplastic was used. shows best to Cracking spalling consume energy. form affects amount energy absorption.

Orthotropic Constitutive Modeling and Tsai–Wu Failure Criterion for Carbon Fiber-Reinforced PEEK Composites

Polymers, Journal Year: 2025, Volume and Issue: 17(8), P. 1076 - 1076

Published: April 16, 2025

This paper performs orthotropic constitutive modeling for short carbon fiber-reinforced polyetheretherketone (CF-PEEK) composites fabricated using material extrusion 3D printing technology. A variety of specimens tensile, compressive, and shear tests are printed under different deposition path patterns. The related experimental results disclose the strong directional mechanical properties, including tensile/compressive modulus strength. Tsai–Wu failure criterion is also developed based on data. tensile–compressive behavior models materials were constructed by importing data into COMSOL, followed a compression simulation S-shaped specimen. test compared with COMSOL-based analysis, which validated effectiveness prediction. predicted timings, locations load–displacement curves all show good agreement observations. Furthermore, index incorporated as stress constraint in structural topology optimization, showing effect significantly reduced concentration. These findings will be supportive design optimization CF-PEEK composites.
