This AC sets forth an acceptable means, but not the only means of showing compliance with the provisions of Title 14 of the Code of Federal Regulations (14 CFR) parts 23, 25, 27, and 29 regarding airworthiness type certification requirements for composite aircraft structures involving fiber reinforced materials, e.g., carbon and . The resin is then "B-staged," or partially cross-linked until it no longer flows at room temperature. It is important to understand that with sensitization reactions, the severity or extent of the reaction does not necessarily relate to the degree of exposure. Although it is more commonly associated with paints and coatings, it can also be caused by contact with matrix resin systems. Therefore a composite structure is really a mixture of critical components. These materials are chemically inert and pose no health risk while in their dry fabric form or when cured in a resin matrix. it constitutes the first large-scale use of a thermoplastic matrix

Unmixed epoxy resins typically come in liquid form and in two parts, the base resin (component A) and the hardener (component B). This work presents a novel strategy for detecting and localizing intra- or inter-laminar damages in composite structures using surface-instrumented strain sensors. Composite designs also last longer than aluminum, which means less maintenance for appearance and overall repair costs. Other quantities can be calculated from the above given figures: So, we can further calculate the fuel consumption in kg/km based on maximum fuel weight and maximum range = 97,000kg/10,458km = 9.275kg/km. So far 1,030 Boeing 787 Dreamliners have already been ordered. When used widely in the context of an entire aircraft, this can make a big difference to its weight, and therefore its efficiency levels and operating costs. Boeing has produced over 1,000 787s to date. Composites have the advantage that they can be formed into almost any shape using the moulding process, but this compounds the already difficult modelling problem. m The remarkable performance characteristics of Kevlar can help increase fuel efficiency and decrease operating and maintenance costs. Modern aircraft are designed to meet performance, properties, environmental standards, and safety. Better
