Abstract: The machining methods such as waterjet cutting, milling, grinding, lapping, etc. are usually used to manufacture glass fiber reinforced composites (GFRCs) parts. Damages will be produced unavoidably in the machining process, no matter which machining method is employed. Subsurface damage is one of the important parameters to evaluate the surface layer damages. The detection method for the subsurface damages of glass fiber reinforced glass matrix (glass/glass) composite after machining is researched. The characteristics of subsurface damages of glass/glass composite after waterjet cutting, milling, grinding and lapping are investigated mainly, when the fiber direction is either perpendicular or parallel to the cutting surface.

Abstract: Young’s Modulus of glass fiber reinforced composites for wind energy applications are studied using numerical method. The effect of volume content of glass fiber on the Young’s modulus of composites is investigated. Results indicate the relation between them is nearly linear. In order to explore the effect of inclined angle of fiber on the Young’s modulus of composites, different finite element models with inclined glass fiber are developed via the ABAQUS Scripting Interface. Results indicate that Young’s modulus of the composites strongly depends on the inclined angle of fiber. A U-shaped dependency of the Young’s modulus of composites on the inclined angle of fiber is found, which agree with the experimental results. The results of the investigation are expected to provide some design guideline for the microstructural optimization of the glass fiber reinforced composites.

Abstract: The paper discusses the influence of cutting parameters such as cutting speed, feed rate and point angle on thrust force and torque while drilling of Glass Fiber Reinforced Plastic (GFRP) composites with Silican Carbide (SiC) fillers. The experiments were conducted during the drilling of GFRP with SiC fillers using four standard twist drills of point angles 90º, 100º, 110º and 120º. Conclusions thus drawn are presented and can be useful for the selection of the best cutting parameters.
