LFRTs differ from the composite structures used in the aerospace industry for components such as aircraft parts. The fibers in LFRTs are relatively short (6.35 mm/0.25 in. or greater) compared to the fibres contained in composite aircraft components. High performance composites usually contain fibers as long as the component itself (6 metres or longer).{{fact|date=August 2013}} Their structural properties and low cost per part have enabled LFRTs to replace metal parts in the automotive industry. In addition, some new organic fibers can even be recyclable. With the independence of choosing the reinforcement from a wide range of fibers and the matrix from a wide range of thermoplastics polymer in the LFRTs, its property can be changed according to customer needs. LFRTs have become an increasingly valuable and popular part of building envelope components such as windows and doors.{{fact|date=August 2013}} ManufactureLFRT components or semi-finished products are made by compression or injection molding. Fibers are contained in the polymer matrix, often in the form of a granulate raw material.[2] Long Fiber Reinforced Thermoplastic Compounds are typically 10-12 mm in length. Fiber is unidirectional along the length of the 12 mm pellet. See also
