composite engineering and manufacturing. the benefits of composite materials derive from the ability to truly engineer the performance of the part by varying thicknesses, fiber angles, material types, and part shapes. these myriad design variables produce inherent complexity that is unique to composite parts, and inextricably link
rtm is a fairly simple process: it begins with a two-part, matched, closed mold that is made of either metal or composite material. dry reinforcement typically a preform is placed into the mold and the mold is closed.
there are three types of composite manufacturing processes: open molding, closed molding and cast polymer molding. there are a variety of processing methods within these molding categories, each with its own benefits.
fabrication of composite materials is accomplished by a wide variety of techniques, including: advanced fibre placement automated fibre placement . tailored fibre placement. fibreglass spray lay-up process. filament winding. lanxide process. tufting. z-pinning.
a composite material is a composition of two or more constituent materials to form an overall structure which significantly better in terms of mechanical or chemical properties than the sum of
composite materials have been utilized to solve technological problems for a long time but only in the 1960s did these materials start capturing the attention of industries with the introduction

compression molding is a manufacturing process in which composite materials are sandwiched between two matching molds under intense pressure and heat from 250 to 400 f until the part cures. this technique is used to rapidly cure large quantities of complex fiberglass-reinforced polymer parts.
hand lay-up. hand lay-up is the most common and least expensive open-molding method because it requires the least amount of equipment. fiber reinforcements are placed by hand in a mold and resin is applied with a brush or roller. this process is used to make both large and small items, including boats, storage tanks, tubs and showers.
instructor should note that composite methods for manufacturing have two basic types of categories for composite processes: open molding resin is impregnated into the fibers and they are placed in an open mold, where
some composite material manufacturing processes and end-products, such as braided composites, are very versatile and are replacing traditional engineering materials such as steel. braided composites have been used in air ducts, fuel lines, fan blades, and automotive shafts 1 and have been explored for orthopedic treatments 2 and for

taking composite materials as a whole, there are many different material options to choose from in the areas of resins, fibres and cores, all with their own unique set of properties such as strength, stiffness, toughness, heat resistance, cost, production rate, etc.
by european manufacturing organizations including composite manufacturers in the early stages of design, notably addressing design for modularity, durability, re- manufacturing and re-cycling through material and manufacturing process selection.
composites consist of two distinct materials, which together improve product performance and/or lower production costs. composite materials typically include plated, clad, or coated metals, however the term 'composites' has evolved to mean a material containing a matrix, or base substance, and a reinforcement material.
in terms of manufacturing advanced fibre-reinforced composites the single most important aspect to recognize is that the material and the structure are created at the same time. consequently any defects that are induced during the manufacturing process directly influence the strength and stiffness of the material and structure.
