You can choose between fibres with critical fibre lengths of 0.4, 0.8, or 1.2 mm, all of which have the same strength and stiffness. Which fibre should you choose to achieve the strongest and stiffest composite? Explain your choice. (4 marks) 15.) designing a composite using short glass fibres and an epoxy resin. You are Page 4 of 11 Mid-year Examinations, 2018 PROD111-18S1 (C) 16.) Define specific heat and thermal conductivity. Why are those two properties important for the perception...
ur thhe spécific for shear, u, and the specific heat of the material. Hence, temperature risc ene machining materials with high strengt cates. The temperature rise at the tool-chip interface is, of course, also a fiu cocfficient of friction. Flank wear (see Section 8.3 and Fig. 8.20a) isction of source of heat, caused by rubbing of the tool on the machined surface. those of the workpiece. generated in the shear plane is a functioll UI material. Hence, temperature rise is...
