Design and manufacturing processes of half face motorcycle palm fiber reinforced composite polymer

Abstract

The Results of palm oil mill processing are palm oil and its derivatives which have high selling value. While the waste is oil palm empty fruit bunches (OPEFB), its utilization is still small. This waste is considered to have good potential to be utilized and developed into composite materials. This study aims to design and manufacture a half-face motorcycle helmet from a polymer composite reinforced OPEFB fiber. The method of making motorcycle helmet by hand lay-up, where polymer composite is applied to a motorcycle helmet mold made of wood with 2 layers on the shell of the helmet. The ratio of OPEFB fiber and polyester resin is based on a mass fraction of 10:90. Obtained a half-face motorcycle helmet with a mass of 1.5 kg and the size of the helmet is for an adult head.

Optimisation of the Partial Runner Set-up Process in Plastic Injection Moulds Using Eight Steps in the Motorcycle Industry

“…Much research has been carried out regarding optimisation in various industries; this is to increase the productivity of employee performance in producing automotive spare parts products at these companies. Injection moulding process design based on product analysis tailored to the proposed design meets production needs in an effective time for manufacturing and leads to the development of similar product designs (Lo et al, 2022;Yani et al, 2022).…”

“…The process of making a motorcycle plastic body consists of two parts, namely the normal process and the partial process (Yani et al, 2022). The material for motorcycle plastic bodies is called Acrylonitrile Butadiene Styrene (ABS) plastic, a type of copolymer composed of several forming monomers that are heat stable, chemical resistant, and have high strength (Wibowo et al, 2023).…”
