Composite materials are widely used today in many sectors. Glass fiber reinforced plastic composite materials are one of those. Glass fiber reinforced plastic composite materials are preferred due to their high thermal and tensile strength. Although consist of glass fiber reinforced composite materials from multiple layers reduces the machinability of these materials, drilling is a common method of machining for these materials. However, when the drilling parameters are not carefully selected, the material integrity is deteriorated and the desired drilling quality cannot be obtained. In this study, the effect of drilling temperature and thrust force on the material integrity was investigated. The drill bit angle, spindle speed and feedrate parameters are used for the temperature and thrust force analysis.

A technique to detect delamination in composite materials by noncontact, rapid and high sensitive microwave reflectometry with a focusing mirror sensor was proposed. The focusing mirror sensor, which has high sensitivity and resolution, is expected to detect delamination sensitively. In this paper, the ability of microwave inspection to detect delamination in glass fiber reinforced plastic (GFRP) and carbon fiber reinforced plastic (CFRP) was verified. As the results, the existences of 100 μm thick delamination in 3 mm thick GFRP laminate and 2 mm thick CFRP laminate were detected.

Abstract Glass fiber reinforced plastic composites are widely used as structural materials. These two phase materials can be tailored to suit a large variety of applications. A better understanding of the properties of the fiber-matrix ‘interphase’ can enable more optimum design of composites. The interphase is a microscopic region around the fiber and hence nano-scale investigation using nano-indentation techniques is appropriate to determine mechanical property variations. In this study the atomic force microscope with the Hysitron indenter has been used to determine the variation of the elastic modulus across the interphase for different silane coated glass fiber reinforced polyester composites. A comparative study of the elastic modulus variation in the interphase is reported. The results are discussed in the light of the current limitations of the instrumentation and analysis.
