  2. National Programme on Technology Enhanced Learning - Wikipedia

    en.wikipedia.org/wiki/National_Programme_on...

    NPTEL courses aim for equitable access. They intended to be available, irrespective of location. Students in non-urban and rural areas can also study via supplementary DVDs and mobile delivered content. NPTEL exams can be written by students no matter where they are located. Assessments take place either at an exam site, or via remote ...

  3. Fiber volume ratio - Wikipedia

    en.wikipedia.org/wiki/Fiber_volume_ratio

    In practice, it's hard to achieve a volume fraction greater than 0.7 and this must be regarded as the realistic limit for commercial materials. In the production process, using different fiber architecture methods can obtain different volume fractions. 2D aligned unidirectional fabrics with pre-preg (usually carbon) fibers are considered to ...

  4. Sintering - Wikipedia

    en.wikipedia.org/wiki/Sintering

    Sintering or frittage is the process of compacting and forming a solid mass of material by pressure [1] or heat [2] without melting it to the point of liquefaction. Sintering happens as part of a manufacturing process used with metals, ceramics, plastics, and other materials. The atoms/molecules in the sintered material diffuse across the ...

  5. Manufacturing engineering - Wikipedia

    en.wikipedia.org/wiki/Manufacturing_engineering

    Manufacturing engineers develop and create physical artifacts, production processes, and technology. It is a very broad area which includes the design and development of products. Manufacturing engineering is considered to be a subdiscipline of industrial engineering/systems engineering and has very strong overlaps with mechanical engineering ...

  6. Cupola furnace - Wikipedia

    en.wikipedia.org/wiki/Cupola_furnace

    The cupola can be made almost any practical size. The size of a cupola is expressed in diameters and can range from 1.5 to 13 feet (0.5 to 4.0 m). [1] The overall shape is cylindrical and the equipment is arranged vertically, usually supported by four legs. The overall look is similar to a large smokestack.

  7. Composite material - Wikipedia

    en.wikipedia.org/wiki/Composite_material

    where X is a material property such as modulus or stress, c, m, and r stand for the properties of the composite, matrix, and reinforcement materials respectively, and n is a value between 1 and −1. The above equation can be further generalized beyond a two phase composite to an m-component system:

  8. Selective laser sintering - Wikipedia

    en.wikipedia.org/wiki/Selective_laser_sintering

    An SLS machine being used at the Centro de Pesquisas Renato Archer in Brazil.. Selective laser sintering (SLS) is an additive manufacturing (AM) technique that uses a laser as the power and heat source to sinter powdered material (typically nylon or polyamide), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure.

  9. Process analytical technology - Wikipedia

    en.wikipedia.org/wiki/Process_analytical_technology

    Process analytical technology (PAT) has been defined by the United States Food and Drug Administration (FDA) as a mechanism to design, analyze, and control pharmaceutical manufacturing processes through the measurement of critical process parameters (CPP) which affect the critical quality attributes (CQA).
