2024年5月3日 · The internal micro-structure of glass and carbon fibre-reinforced polymer (FRP) rebars subjected to tensile loading was investigated using micro computed tomography (μCT) and scanning electron microscopy (SEM) images.

2020年11月1日 · The tensile strength and elastic modulus of a fiber reinforced polymer (FRP) bar are directly related to the percentage of fibers measured by weight or volume. Recognizing the increasing number of different commercially available FRP bars, the implementation of precise methods for quantification of constituent fractions is of high importance to ...

本文分析了从本科和研究生12年的断裂学和失效分析课程中收集的sem断裂图，所有被研究的非金属材料（玻璃、塑料、frp和木材）都是在受控条件下断裂的，因此断裂主要是由拉伸、扭转、单向弯曲、反弯疲劳和冲击等一种加载方式造成的。

2021年1月1日 · The mode of failure is affected by wettability of the fibre by the matrix. A poor wettability results in a poor matrix-fibre interfaces as revealed by the SEM fractographs presented in Fig. 2 which exhibits a clean fibre surface on the fragmented surface of the specimen indicating poor wettability of the glass fibre by the matrix [13]. However ...

Fiber-reinforced polymer (FRP) composites are becoming more frequently adopted as so-called “corrosion-resistant” concrete reinforcement materials due to their excellent mechanical...

2021年11月20日 · In this paper, a random field modeling technique for a digital image of microstructure of a unidirectional fiber reinforced plastic (FRP) is presented, and the multiscale stochastic stress analysis with considering a random fiber arrangement in FRP based on the random field model identified by the presented method is attempted.

2014年1月1日 · A measurement of deformation at micro area of CFRP is performed with digital image correlation method. Tensile testing is developed to perform in scanning electron microscope, and obtained SEM images are used. Charge up and edge effect is seen around edge of fiber cross section, countermeasures must be worked out since it affects to result ...

Fiber-reinforced polymer (FRP) composites have gained widespread applications in many engineering fields, making it imperative to study long-term performance under service...

This paper analyzes a collection of SEM fractographs compiled from 12 years of undergraduate and graduate level courses on fractography and failure analysis. Each nonmetallic material studied (glass, plastic, FRP, and wood) was fractured under controlled conditions so that the fracture was due mainly to

2023年8月17日 · Tensile strength measurement exhibited a significant effect of silanization on the mechanical performance of the fiber-reinforced polymer (FRP). FE-SEM cross-sectional images illustrated...
