What are the 3 categories of composite materials?

Are the composite areas divided into several parts having simpler shapes?

Do the strength characteristics of wood vary greatly from one species to another?

Two solid steel shafts are fitted with flanges which are then connected by fitted bolts so that there is no relative rotation between the flanges. Knowing that G= 77 GPa, determine the maximum shearing stress in each shaft when a 500 N-m torque is applied to flange B. (3 3.0 36 mm 30 mm T= 500 N · 1 C 900 mm 600 mm 2os.of

In general, polymers have lower strength, hardness, stiffness, density, and temperature resistance compared to ceramics. T or F

You have been tasked to design and fabricate a set of low cost, lightweight, constant “C” cross-section side rails for a new composite production ladder. What (a) fiber type, (b) resin type, (c) product form and (d) fabrication process would you select and why for each above?

What kind of properties can be changed by post treatment of 3D printing parts plastics?

Question 2: A GFRP product is made from: 7.0 mm long by 0.002 mm diameter aligned fibres with Ef​ =72.5GPa and a tensile strength of 3.5GPa, and a matrix material with Em​=1.6GPa and a tensile strength of 41.4MPa. The stress in the matrix at the fibre fracture strain is 20MPa. a) If the shear strength of the fibre-matrix bond is τc​=10MPa then determine the longitudinal composite strength (σ∗) when the GFRP is made with ϕf​=0.4. b) Determine the stiffness of this GFRP product in the longitudinal and transverse directions. c) If it were possible to modify the design of this GFRP product, determine the volume fraction of fibre that would be needed to achieve a strength (σ∗) of 2000MPa
