“…Based on the identified failure mechanisms in the composite laminates, two implications on actual composite component may be anticipated: (a) the formation of surface cracks and crack network in Baseline material will compromise the structural integrity; (b) early detection of damage, due to aging, in Thin‐ply composites may be problematic. As summarized by Arteiro et al [ 15 ] , changing the type of damage from matrix cracking‐induced delamination to free‐edge delamination, delays degradation of mechanical properties, thus laminate failure is also suspended. A potential issue with identification of damage in Thin‐ply components may arise, since free‐edge delaminations cannot be detected by visual inspection, contrary to the surface cracks easily observed in Baseline material.…”

“…It is well known that reduction of ply thickness increases the in-situ transverse ply strength for traditional epoxy-based composites and delays the transverse cracking of the matrix. [12][13][14][15] To the knowledge of the authors, there currently exist very few studies on thin-ply (≤100 μm) composites with polyimide resin. [16,17] The current article reports on the potential influence of thin-ply reinforcing layers on the long-term thermal stability of high-temperature polyimide-based carbon fiber composites, in which manufacturinginduced residual stresses are significant.…”

Thermal oxidative aging of satin weave and thin‐ply polyimide composites

The weight loss and damage development of satin weave and thin-ply carbon fiber-reinforced polyimide composites are studied during high temperature (288 and 320 C) aging in air. Two distinct regions are identified in the weight loss measurements-a rapid initial desorption and a subsequent slower weight loss, which is attributed to matrix degradation. The initial desorption stage is modeled by combining material constitutive properties from literature, micromechanics and a one-dimensional Fickian diffusion model. Two different damage patterns are observed by using optical microscopy and X-ray computed tomography on specimens before and after aging. Crack clusters form a network in satin weave composites, while edge delaminations are observed in thin-ply laminates, which are known for their enhanced resistance to matrix cracking.

With the development of spread-tow, thin-ply technology, ultra-thin composite laminates could be produced. Composite bolted joints are commonly used on aircraft’s load-bearing structures and are considered the main cause of stress concentration. The aim of this research is to investigate the bolted joint behavior of composite laminates that combine thin-plies and conventional thick-plies in a predetermined stacking sequence. The impact of thin-ply placement within the stack on bearing strength, including the onset of damages, is examined. The work involves mechanical tests and fractographic activities to understand the damage mechanisms of the plies and their interactions, and its reflections on the bearing load capacity of the joint for double-lap bolted joints. The results showed an improvement in the bearing strength of up to 19% by inserting the thin-plies inside the laminate. The visual examination of the specimens showed a bearing damage mode for all the tested specimens. The computed tomography scans showed damage mechanisms that mostly occurred with the normal plies, rather than breaking the thin-plies. For the specimens of traditional plies, delaminations were noticed at most of the interfaces. For the one with a block of thin-plies in the middle, all the delaminations were forced to the surface layers with an extra large size. Forspecimens with distributed thin-plies, a higher number of smaller delaminations was recognized.

“…Since loading the resin is not a reasonable practice, the design has been restricted to structure that experience mainly in-plane loads. [7,8] Besides, the delamination resistance between the individual lamina in the laminated composite is ordinarily very poor due to the lack of reinforcement fiber in the through-thickness direction. [9] With the introduction of 3D textile structure, the barrier to composite design can be eliminated.…”

In this research, orthogonal structure carbon fiber reinforced composite was developed and its properties were compared with those of laminated structure composite. To solve the problem of yarn damage caused by friction during the weaving process, a custom-built weaving device was build up. Compression and vacuum-assisted resin infusion molding (VARIM) techniques were selected and compared. It was found that fiber geometries could be well retained using the later one. The orthogonal and laminated composites prepared by the VARIM technique with the fiber volume fraction were 32.76% and 38.64%, respectively. Flexure and impact tests were performed to evaluate the properties of laminated and orthogonal composites. The results show that orthogonal composite exhibits superior properties in the warp and weft directions. In addition, due to its straight yarn path and insertion of carbon fiber in the through-thickness direction, orthogonal fabric reinforced composite exhibits an improved bending strength over composites reinforced by laminated plain woven fabric, although the fiber volume fraction of orthogonal composite is much lower than that of laminated composite. The findings indicate that orthogonal structure composite provides profound guiding significance for product development and application of carbon fiber composite.
