Fiber-reinforced plastics (FRPs) are usually an epoxy resin or thermoplastic resin reinforced with glass ﬁber, carbon ﬁber, or natural ﬁbers. So, FRPs have the excellent mechanical properties of their components.
Carbon Fiber-reinforced Plastic (CFRP)
CFRP is used for airplane parts because it has high speciﬁc strength and high speciﬁc stiffness. We investigate the interlaminar fracture toughness and creep property of CFRP, and we design and manufacture CFRP joint parts for electronic vehicles by using the ﬁnite element method.
Natural Fiber-reinforced Plastic (NFRP)
NFRPs, which consist of natural ﬁbers in thermoplastic resin, are alternative materials to glass ﬁber-reinforced plastic. In Europe, hemp ﬁber is mainly used for buildings and automobile parts. However, we examine the mechanical properties of NFRPs containing jute, kenaf, and bamboo ﬁbers.
Green composites are NFRPs made from a biodegradable thermoplastic resin like PLA that address the problem of plastic waste. We examine the mechanical and biodegradable properties of green composites.
