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 ...
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 ...
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:
Sulfur at harbor in North Vancouver, British Columbia, ready to be loaded onto a ship Latex being collected from a tapped rubber tree. A raw material, also known as a feedstock, unprocessed material, or primary commodity, is a basic material that is used to produce goods, finished goods, energy, or intermediate materials that are feedstock for future finished products.
Manufacturing resource planning (MRP II) [1] is a method for the effective planning of all resources of a manufacturing company. Ideally, it addresses operational planning in units, financial planning, and has a simulation capability to answer " what-if " questions and is an extension of closed-loop MRP (Material Requirements Planning).
Textile manufacturing or textile engineering is a major industry. It is largely based on the conversion of fibre into yarn , then yarn into fabric. These are then dyed or printed, fabricated into cloth which is then converted into useful goods such as clothing , household items, upholstery and various industrial products.
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.
Value engineering can lead to the substitution of lower-cost materials, as with the exterior cladding that accelerated the Grenfell Tower fire in London. [1] [2]Value engineering (VE) is a systematic analysis of the functions of various components and materials to lower the cost of goods, products and services with a tolerable loss of performance or functionality.
