Tensile Strength of Glass Fiber-Reinforced Plastic by Fiber Orientation and Fiber Content Variations

Abstract

For unidirectional composite material, there is a theoretical mixture rule equation to calculate the strength of composite from properties of matrix and fiber content. However, the equation for tensile strength with the fiber content and the fiber orientation is not available. Therefore, this study was investigated what affect fiber content and fiber orientation have on the strength of composites. Glass fiber-reinforced plastic by changing fiber orientation and fiber content was made. Tensile strength of 0° direction of composites increased being proportional fiber content and fiber orientation function as change from isotropy (J=0) to anisotropy (J=1). But, tensile strength of 90° direction by separation of fiber filament decreased when tensile load is imposed for width direction of reinforcement fiber length direction. In this study, empirical equation to estimate tensile strength out of fiber orientation and fiber content was proposed.

Tensile and flexural properties of MWCNT-COOH and hBN integrated polyamide 66/short glass fiber composites

“…Among a variety of fillers, glass fibers are extensively preferred owing to their ability of increasing the stiffness and heat resistance of the composite as well as their relatively low processing costs [10]. Addition of glass fibers into PA 66 matrix up to a certain ratio leads to a large amount of improvement in the mechanical properties [11][12][13][14][15][16][17][18].…”

High-Cycle Fatigue Life Behaviour of Fabricated Glass Fibre-Reinforced Polymer

“…The subsequent growth of these cracks and delamination eventually leads to the final failure or fracture of materials [38]. In addition to [14,15,18], these studies [39][40] also conducted static and cyclic tests on GFRP specimens, but the fibre was varied with chopped fibre type and fibre mat.…”

Effects of glass-mat on mechanical anisotropy in bidirectional e-glass woven roving reinforced composite sheets produced by RTM method

“…Kırpılmış mat keçelerin uygulamada önemli avantajları vardır [1], [2] [6], fiber oryantasyon fonksiyonu veya faktörü [7]- [9] ve fiber oryantasyonunun veya mekanik anizotropinin çekme dayanımı ve elastisite modülüne etkisi [10] ile ilgili çalışmalar mevcuttur. Bu çalışmaların bazılarında, fiberlerin ±45° yönde bulunduğu dayanım değerinin minimum hatta matrisin kendi dayanımı olarak bile kabul edilebileceği ifade edilmektedir [4].…”
