In today's manufacturing industry, composites are widely used. This is primarily due to the highly variable material properties that can be obtained by combining various materials as reinforcements and matrices. However, modern environmental concerns have pushed researchers engineers seek from organic renewable sources. The study will look into composite surface roughness during cutting process...

Abstract The fiber reinforced polymer (FRP) armor composites are kinds of composite materials specially designed and manufactured to prevent the penetration high-speed bullets fragments. FRP commonly composed reinforcing fibers, resin matrix their interfacial structures. vinyl ester (VER) is a kind thermosetting applied in field high performance bulletproof composites. However, VER has problem ...

Kaiwen Liang, Hossein Toghiani, and Charles U. Pittman Jr. Dave C. Swalm School of Chemical Engineering, Mississippi State University, MS 39762. Department of Chemistry, Mississippi State University, MS 39762. Carbon-carbon materials are traditionally designed for high temperature applications. Carbon-carbon materials are composites formed by impregnating continuous carbon fiber cloths or prefo...

This paper presents the fabrication process of custom-made mouthguard with added features of air flow channel by using rapid tooling approach. Impression process was conducted in order to produce dental stone that will be used in thermoforming process to fabricate the custom-made mouthguard. Computer-aided design (CAD) were utilized to prepare the air flow channel’s design before attaching it a...

Cyanate ester resins offer advantages as composite matrices because of their high thermal stability, low outgassing, low water absorption, and radiation resistance. This paper describes the results of a processing study to develop a high-strength hoop-wound composite by the wet-filament winding method using Toray T1000G carbon fiber and YLA RS-14A cyanate ester resin as the constituent material...

Abstract This work presents a numerical approach to multi-routines based on experiments, and, with target analyse strength of cross-ply glass fibre reinforced plastics (GFRP) composite after immersion in sulphuric acid solution under pressure (5% H 2 SO 4 solution, 95 °C, 15 bar). Two alternative vinyl ester resins (bisphenol A diglycidyl ether and epoxy phenol novolac) were investigated. After...
