In this paper, a high-temperature test experimental system is built to investigate the dependence of the strength of a C/SiC composite material on temperature. Unintuitively, the strength increases with temperature. To investigate the microscopic mechanism, scanning electron microscopy (SEM) of an in situ bending test experiment is performed. Our h...

During curing process of composites, residual stresses inevitably develop and play an important role in the final mechanical properties of composites. Therefore, the consideration of residual stresses when designing composite structure is necessary. The causes of residual stresses are well known on the part and fiber-matrix level. However, the infl...

The original version of this article unfortunately contained a mistake. Fig 2 was captured incorrectly. Since the analysis of bird-strike in the paper was carried out with Abaqus, it was replaced by a picture of the analysis process of Abaqus' bird-strike. The corrected Fig 2 is now given

Carbon fiber-reinforced carbon (C/C) composites consist in a carbon matrix holding carbon or graphite fibers together, whose physical properties are determined not only by those of their individual components, but also by the layer buildup and the material preparation and processing. The complex structure of C/C composites along with the fiber orie...

One of the main disadvantages of the regular sinusoidal corrugated core sandwich panels is dependency of their bending properties on its arrangement. To resolve the disadvantage, a bi-directional sinusoidal corrugated core panel was proposed. Hence, the influence of the waves number on the flexural properties of the panels with bi-directional or re...

This paper presents an effective and reliable non-destructive method to measure the Young Modulus of porous and out of plane Young Modulus of composite materials using sound waves. First, a Finite Element Model based on Representative Volume Element (RVE) is developed to demonstrate how the elastic properties of composite material can be estimated ...

Reactive thermoplastics are advantageous for wind turbine blades because they are recyclable at end of life, have reduced manufacturing costs, and enable thermal joining and shaping. However, there are challenges with manufacturing wind components from these new materials. This work outlines the development of manufacturing processes for a thick gl...

In this paper, a multiscale analysis strategy was proposed to analyze the failure behaviors of open-hole compressive (OHC) CFRP laminates. Micro-level intralaminar failure was defined in the constituents (fiber and matrix) with a modified micromechanics failure theory. In the multiscale stress transformation, the effect of thermal residual stress w...

Drilling is commonly adopted in the manufacturing process of large CFRP structural components for meeting assembly requirements. However, undesirable burrs occur frequently due to the weak restrictive conditions at hole-exit and the excessively high cutting temperature, decreasing the components’ assembly performance. This study aims to propose a n...

The direction factor of the bending stiffness was defined in terms of the proportional coefficient of the bending stiffness corresponding to the identical ply orientations, as well as a new iterative mode, cycle after symmetry, of the laminate. On the basis of the quasi-isotropic laminate, the method of the direction factor of bending stiffness con...
