L&L Products is a provider of individual and innovative engineering solutions to the automotive industry and is known for superior engineering through the use of state-of-the-art simulation methods in the product development chain. However, they faced the challenges in moving towards greener technology by replacing classical metal design with composite structures. The purpose of transitioning was to utilize the outstanding performance of composite materials. However, this presented difficulties, mainly with predicting the injection molding process and achieving a high-quality prediction of the impact on a short fiber reinforced stiffener beam.  

The James Webb Space Telescope is a highly sensitive instrument that is positioned using a precise optical metering support structure. This supporting structure is made from composites to reduce thermal expansion effects while reducing weight. The instrument and structure are subjected to temperatures ranging from ambient during launch to cryogenic temperatures while in orbit. Dynamic and static loads are encountered during launch and in operation respectively.

Designing Spinal Disc Prosthesis Implants Using Short Fiber Reinforced Composites   Spinal injury and the gradual deterioration of spinal discs that lead to back pain or spinal disorders can be treated surgically. One of the most promising surgical options under continuous development is the use of artificial discs to replace the patient’s natural spinal disc. …

To reach their goal of complying with CO2 regulation, Trelleborg uses material modeling and simulation software.   Challenge To comply with CO2 regulations (2015: 130g   2020: 95g) To reduce the average weight of a car by 200 kg …

Some of the most significant challenges facing the automotive industry include raw material cost, light-weighting and achieving mass production. These are direct consequences of environmental requirements becoming more rigorous as concern about carbon emissions grows. Moreover, the use of carbon fiber is an important part of the answer to these problems but brings on its own set of issues that need to …

The complexity of composites vs. traditional metallic materials has forced aerospace manufacturers to complete 7-20x more tests than before across all levels of the validation pyramid. With smaller tests costing around $1k-$5K, and the larger tests costing up to $1M-$3M, a significant barrier has been presented in terms of cost and time to validate their …
