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 ...
NPTEL is the largest e-repository in the world of courses in engineering, basic sciences and selected humanities and management subjects. [1] The platform and materials have been jointly developed by Indian Institutes of Technology (IITs) and Indian Institute of Science. [2] The initiative is funded by the central Ministry of Education. The ...
Textile testing is the process of evaluating the quality and properties of a textile material through a series of tests at various stages of manufacturing. [1] Textile testing, like textiles, is a vast subject.
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.
The manufacturing readiness level (MRL) is a measure to assess the maturity of manufacturing readiness, similar to how technology readiness levels (TRL) are used for technology readiness. They can be used in general industry assessments, [ 1 ] or for more specific application in assessing capabilities of possible suppliers.
PAT is a term used for describing a broader change in pharmaceutical manufacturing from static batch manufacturing to a more dynamic approach. It involves defining the Critical Process Parameters (CPPs) of the equipment used to make the product, which affect the Critical Quality Attributes (CQAs) of the product and then controlling these CPPs ...
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).
Material requirements planning (MRP) is a production planning, scheduling, and inventory control system used to manage manufacturing processes. Most MRP systems are software -based, but it is possible to conduct MRP by hand as well.
