Effects of ply thickness and 0°-layer ratio on failure mechanism of open-hole and filled-hole tensile tests of thin-ply composite laminates

Ryoma Aoki et al.

Summary: Thin-ply technology offers more possibilities for composite structures, allowing for variations in ply thickness and laminate layup. This study investigated the effects of ply thickness and 0 degrees-layer ratio on the strength and damage behavior of thin-ply composite laminates, finding that thin-ply can reduce strength and a higher 0 degrees-layer ratio leads to increased strength with a transition to splitting-dominated failure. Additionally, finite element analysis indicated that fastener restraint can alleviate stress concentration, potentially impacting tensile strength.

Pavel Simacek et al.

Summary: This study investigates the mechanisms for filling gaps during the consolidation of thermosetting composites, finding that percolation flow may be involved in addition to squeeze flow. A model is proposed to predict the spreading of fiber/matrix suspension and resin percolation into the gaps, with experimental validation of the predictions.

Multi-fidelity progressive damage simulation of notched composite laminates with various thicknesses

R. Higuchi et al.

Summary: In this study, a multi-fidelity fracture simulation scheme is developed for composite laminates. The scheme combines smeared crack models (SCMs) and discrete crack models (DCMs) to achieve a seamless transition and reduce computational cost while maintaining prediction accuracy. The proposed scheme is validated through simulation of open-hole tensile tests and comparison with experimental results.

The comparison of the veritable response to impact load of conventional and Thin-Ply types of fibre metal laminates

Patryk Jakubczak

Summary: This study compared the response of Aluminium/Thin-Ply-Glass laminates and conventional Aluminium/Glass laminates to impact, finding similar failure mechanisms but differences in individual failure modes that may affect damage propagation. The earlier perforation initiation of thin-ply FMLs is attributed to the domination of bending stress over tensile stress.

Damage-mechanics mesoscale modeling of composite laminates considering diffuse and discrete ply damages: Effects of ply thickness

Ryoma Aoki et al.

Summary: The study focuses on the damage evolution of thin-ply composites and proposes a mechanics model that considers diffuse and discrete interply damage. Loading and unloading tests were conducted to evaluate the influence of ply thickness on damage evolution, resulting in formulated damage evolution laws dependent on ply thickness. The proposed model successfully captures the retardation and suppression effects of thin-ply, and accurately predicts stiffness degradation and failure strength of laminates with different ply thicknesses.

An investigation into fatigue behaviour and damage progression in pseudo-ductile thin-ply angle-ply laminates

X. Wu et al.

Summary: The study showed that pseudo-ductile thin-ply angle-ply laminates can withstand 106 cycles under 80% yield stress without obvious damage or stiffness reduction. In fatigue loading with pre-fractured 0 degrees plies, a delamination dominated damage mode was observed in both laminates.

Experimental investigation on bearing behavior and failure mechanism of double-lap thin-ply composite bolted joints

Yuejie Cao et al.

Summary: Thin-ply laminated composites have gained attention in aerospace engineering due to enhanced design possibilities and positive size effects. This study experimentally investigated the mechanical behavior of thin-ply laminate and TC21 titanium alloy hybrid joints under quasi-static loading, revealing a more gradual bearing damage progression and a combination of bolt cracking and hole bearing deformation in the final failure of hybrid joints. The suppression of standard-ply composite laminated plates delamination in thin-ply laminates resulted in higher bearing failure strength and more damage accumulation.

Gap filling mechanisms during the thin ply Automated Tape Placement process

Navid Niknafs Kermani et al.

Summary: Automated Tape Placement (ATP) is an attractive automated composite manufacturing process that reduces labor cost, increases production rate, and improves repeatability by building parts with unidirectional prepreg tapes. However, inevitable defects such as gaps between neighboring tapes during lay up present challenges in this method. This paper presents a model to simulate the gap-filling process and proposes predictions for resin flow and gap thickness, which are validated by experimental results and micrographs.

Fatigue and fatigue after impact behaviour of Thin- and Thick-Ply composites observed by computed tomography

Benedikt Koetter et al.

Summary: This study investigates the influence of load ratio and impact damage on the fatigue behaviour of high-performance carbon fibre reinforced polymers (CFRP) with different areal fibre weights. The results show that both static and fatigue performance improve with decreasing layer thickness, especially under tension-compression loading. Additionally, low-energy impact has different effects on Thin- and Thick-Ply laminates, with Thin-Ply laminates able to sustain higher stresses and cycles without increasing damaged area during fatigue compared to Thick-Ply laminates.
