The overall performance of composites is influenced by the constituent materials, their distribution and their interaction. The properties of the composite structure are determined by the properties of fibre and resin, ratio of fibre to resin in the composite (fibre volume fraction) and geometry & orientation of fibres in the composite.This paper discusses about,extensive coupon
The need for robust processes in Service Organizations need not be debated. In a servicesecosystem, operating processes differentiate a greatorganization from a good organization.At Quest Global, a study of the portfolio of our strategiccustomers provides evidence of high quality processesand practices being implemented in their business. Eachone of these is an industry leader and all
Composites are an integral part of structural design in the areas of Aerospace, Automotive, Marine, Construction, Manufacturing, etc. Due to high strength to weight ratio and at times, they are also replacing metallic structures. However, these materials are not typically applied in isolation due to insufficient stiffness and ductility of the FRP compared to traditional
Structural health monitoring (SHM) of Aircraft composites is gaining prominence in the aero industry. Among the available SHM systems for Composites, usage of embedded fiber optic sensors for temperature, strain, pressure, acoustic emission, etc. is increasing due to their smaller size (~125 microns). This requires an understanding of the complex sensor architecture, type of sensing
This paper presents the finite element (FE) analysis of top hat stiffeners (manufactured using vacuum assisted resin transfer moulding (VARTM)) under static load where laminate splitting/delamination is the primary mode of failure. A set of experiments are conducted on composite top hat stiffeners with three different layup arrangements. The experimental study together with FE modelling
Software Testing is the last phase in software development lifecycle which has high impact on the quality of the final product delivered to the customer. This paper describes on a Test Automation framework that supports the concepts of Continuous Integration, Virtualization, Internationalization and Multiplatform. The framework does not wait for the final stage of life
In today’s competitive software development scenario, the customer demands a testing coverage which not only ensures the stated requirements but also the implied ones. This situation calls for an exhaustive testing which may not be always possible due to various reasons. This paper explains the concept of Adaptive Random Testing in which each test case
Aero engine design is a complex process involving multiple disciplines, which collaborate iteratively to achieve an optimized design. This involves exchange of data (geometry, process files, CAE data and engineering significant parameters) at component, subsystem and system levels. The building blocks of this process have usually been in the form of in-house developed software.
This paper discusses about Acoustic emission technique where in the minute cracking noise sensed using both piezo-electric and fibre optic sensors. Fibre optic sensors could effectively be used as a sensor to measure Temperature, Strain, Pressure, etc. Surface bonded Piezo-electric and fibre optic sensors – Fibre Bragg Grating (FBG) are used to sense Acoustic Emissions
Production Part Approval Process (PPAP) is a well-accepted and organized system in various industries including Aerospace & Automotive. The aerospace industry is facing challenges in terms of resource, pressure to save cost and the implementation of this APQP / PPAP being new. Thus the need is for a proven system, which is resourceful and addresses
