Fibre-reinforced polymer composites (FRPCs) are playing a significant role in manufacturing of goods/products in service for lightweight applications. Among FRPCs, natural fibre-reinforced polymer composites (NFRPCs) are one in forefront and replacing both the conventional and unconventional reinforced composites since they are eco friendly in nature and have several benefits like low price, ease of manufacturing, denseness, biodegradability, etc. In this chapter, a solemn attempt is made to study the pineapple leaf fibre (PALF) bolstered with polymer matrix composites (PMCs). PALFs are rich in cellulose, comparatively cheap and extravagantly available. PALFs reinforced with polymers such as thermoplastic/thermoset matrices are widely used in automotive sectors. PALF-reinforced polymer matrix composites have a wide range of applications in automotive industries, manufacturing of dashboards, package trays, door panels, headliners, seat backs, interior parts and many other parts. This chapter also explores the type of NFRPCs used by several automotive organizations. © Springer Nature Singapore Pte Ltd. 2020.
