PMI Foam Of Tasuns Enter Into Production Cars

Tasuns Composite Technology Co.,Ltd | Updated: Sep 29, 2017

With the demanding requirement of the automotive energy saving and emissions reductions at domestic and abroad, in Oct. 2016, Energy saving and new energy vehicle technology roadmap, released by Society of Automotive Engineers of China pointed out that compared with 2015, vehicle weight will be reduced by 10% by 2020, 15% by 2025 and 35% by 2030. Accordingly, lightweight design are significantly practical for automakers and the prospect of automotive plastics is much clearer.


Take the automobile engine hood as an example, considering its structure, safety (strength, stiffness, modality), surface (Class A surface and painting requirements), cycle time etc., material and part suppliers propose their own solutions with composites. Today PP&LGF, which applies to engine hood with small projection area,and carbon fiber composites are into the mass production on automotive OEM factories.

After a comprehensive comparison of material properties and processing technologies among PP, LFT and SMC etc., SanHe Auto New Material Co., Ltd. designed and developed lightweight engine hoods using RTM technology and into mass production. It uses GFRP skins and PMI rigid foam core made by Tasuns. The sandwich hood mechanical properties improve 10% more than metal part while the weight decreased over 30%. The RTM parts can also satisfy the requirement of Class A surface, complex surface and reliable joint.
