Teijin develops extra-light Automotive Side-Door Module made of advanced Composites

Teijin Side-Door ModuleTeijin Limited brought it to everyone’s delight with an announcement that its automotive composites specialty groups have recently developed a multi-material composite automotive door concept. This innovation makes it possible to maintain required crash specifications while reducing overall weight by 35% as compared to a conventional steel door.

Teijin Composites Innovation Center (TCIC) and Continental Structural Plastics Holdings Corporation  (CSP) have worked jointly to develop this prototype involving unique approach. This will be on display at JEC World 2019 held in Paris.

This module is composed of carbon fiber sheet molded compound (SMC), glass fiber SMC and unidirectional glass fiber reinforced plastics (GFRP) which offers high strength and low weight. its manifold benefits are cost efficiency, ability to achieve deep draws and superior design freedom not achievable with a metal. Moreover, this pioneering solution can also bear the heat level of the conventional E-coat automotive painting process.

Tough, lightweight, eco-friendly modules are becoming really popular, specifically in Europe. This is for automotive components like resin-based tailgates, bonnets (hoods) and roofs which help in reduction of CO2 emissions.

Multi-material side-door modules for high-volume vehicles have been realized by some automakers. However, they still are particularly challenging for designers as these components must meet especially demanding requirements for shock absorption to protect passengers in crashes, fatigue resistance to withstand the stresses of repeated opening and closing and accommodate interior harnesses for electrical wiring and signal components.

Teijin plans to stay committed towards the enhancement of the quality of its side-door module capabilities by applying various high-performance materials and technologies available within the Teijin Group.  Teijin’s ultimate goal is to launch a commercial door module by 2025 and emerge as a global supplier of the multi-material automotive components. Also, it’s striving to achieve the target sales of around $2 billion by 2030.
