Abstract
Purpose
This study aims to systematically compare the effect of increasing fiber–matrix interface adhesion and matrix toughness in layered composite materials.
Design/methodology/approach
Silane ((3-glycidyloxypropyl) trimethoxysilane) was applied to strengthen the fiber–matrix interface connection in e-glass/epoxy laminated composite material. Using a cationic surfactant, 0.1% multi-walled carbon nanotubes (CNTs) were added to the matrix in two different ways, by with and without chemical functionalization using the vacuum infusion method.
Findings
In the results obtained from the three-point bending test specimens, it was determined that the synergistic effect of silane application and non-functionalized CNT in the matrix was higher in terms of flexural modulus and strength values.
Practical implications
The functionalization of multi-walled CNT did not give the expected results because of reasons such as viscosity increase and agglomeration in the matrix.
Originality/value
In this study, a simple model for normalization and prediction purposes was developed, which allows the determination of the flexural modulus and un-notched flexural strength values from one test result of the notched specimen. A systematic comparison was performed by varying each parameter in the composite material.

Abstract
With the rapid development of technology in the era of digitalization, Industry 4.0 has become a reference for R&D studies in various sectors. The rapid development of technology makes the life of societies and people easier. For this reason, governments tend to develop their technologies and to encourage organizations in this field for this purpose. The concept of Industry 5.0 or Society 5.0 explains the revolution in people's lives with the development of the Fourth Industrial Revolution. Today, many interrelated factors are rapidly preparing people for a complex and volatile future. This situation is accepted as the “new normal” and is defined as VUCA-RR (Volatility, Uncertainty, Complexity, Ambiguity, Rapidity, Radicality). Variability refers to the increasing pace of change, uncertainty, unpredictability in life. Complexity indicates difficulties in relationships in life, and ambiguity indicates difficulties in understanding the events around us. The advancement and widespread use of digital technologies will enable organizations to develop sustainable strategies by providing them with the opportunity to grow by achieving sustainable competitiveness and profit in the VUCA-RR environment.
