Course Length: 5 days
Pre Requisites:
M-2 Advanced Composite Manufacturing 2
Summary:
This course is designed as follow-on to the M-2 (Manufacturing 2) course and is intended for those wanting to further their knowledge of composite manufacturing, whether in preparation for employment in the advanced composite manufacturing industry, or as engineers or technicians desiring a further understanding of the practical skills involved in producing quality composite structures.
Introduction:
At the end of Manufacturing 3 the student will have an intermediate level knowledge of machining, trimming and drilling composite components using fixtures, surface preparation methods/secondary bonding of structures, component assembly methods and techniques, as well as a acquire a fundamental knowledge of the resin vacuum infusion manufacturing process.
