Open Hole Tension of Coir-angustifolia Haw Agave Fibers Reinforced Hybrid Composite after Drilling Process

Abstract

The aim of this paper is to investigate notched (open hole) tensile strength and normalized strength of coir and angustifolia Haw agave fibers as reinforcement of hybrid composites. Fabrication of hybrid composite with coir and agave fibers as reinforcement and polyester as the matrix was performed. Coir and agave fibers were formed like a mat.Notched (open hole) hybrid composites were drilled with 6 mm diameter of a hole at center of samples. Tensile testing was conducted to unnotched and notched hybrid composite. Results showed that tensile strength decrease after drilling of a hole in hybrid composite sample center. Normalized strength was range between approximately 75-98%. Tensile fracture of notched samples based on the view of images was around the hole due to concentration stress.
