Advanced High Strength Steels (AHSS) are now commonly used in automotive body structural applications. The high strength of this grade classification is attractive to help reduce mass in the automotive body through reduction in thickness. Strength also supports improvements in safety requirements so that mass increases are minimized. In some specific grades of AHSS, energy absorption is possible in addition to the high strength. This course will review the definition and properties of AHSS and cover several common applications in automotive body structures.

The purpose of this session is to describe solutions for weight savings, which is a well-known strategy for improving fuel consumption in vehicles, and to explain the NVH impact of these weight reductions. Weight savings can come from interior and structural parts of vehicle in the form of one of the following solutions: composite materials, light weight alloys, aluminum & magnesium versus steel, bonding dissimilar materials, new damping compounds, elimination of mass barriers, higher performance acoustical products, reduction of part weight, reduction of part size, material substitutions, or reduced complexity of parts. NVH countermeasures for these weight reduction solutions will be outlined so that lightweight design for next generation vehicles can be implemented with attention to noise and vibration throughout the vehicle.

Superhydrophobic coatings have shown promise in reducing ice adhesion on a surface. However, recent superhydrophobic ice adhesion studies were conducted at either ice accretion conditions that do not resemble aerospace icing conditions, or at low super-cooled droplet impact speeds (less than 10 m/s). Therefore, a detailed experiment was conducted to measure the ice adhesion strength of various superhydrophobic coatings in an icing wind tunnel at an air speed of 50 m/s and at a temperature of -15°C with a super-cooled icing cloud consisting of 20 µm droplets. The ice was accreted on 3 mm thick, 30 mm diameter discs and then removed by pressurized nitrogen through the access hole in a tensile direction for a measurement of the ice fracture energy. Results showed no relationship between coating wettability parameters (water contact and receding angles) with ice fracture energy but depicted a general increase in fracture energy with increasing surface auto-correlation lengths.

Ideally, an icephobic coating applied to ice-exposed surfaces appears to be an interesting solution to prevent ice build-up. Over the last decade, developments of efficient icephobic coatings were multiplied. Some materials that reduce ice adhesion have been developed from which the ice can be more easily shed, possibly even with existing forces such as wind, gravity and vibrations. This paper will depict icephobic coating performances of 262 different coatings and 11 grease type substrates tested over the past 10 years at the Anti-Icing Materials International Laboratory (AMIL). Since 2003, the icephobic performance is evaluated with two main test methods. A first test method was developed in regards to measuring the ice adhesion and its reduction. A second test was then developed to measure the ice accumulation reduction.

The formation of ice on surfaces of technical devices or transportation vehicles can lead to several problems, like reduced functionality, reduced energy efficiency or operational safety. As known de-icing methods use a high amount of energy or environmentally harmful chemicals, research has focused lately on passive de-icing by functional surfaces with an improved removal of ice (de-icing) or a reduced formation of it (anti-icing). Inspired by the Lotus plant leaf from nature, a “super-hydrophobic” surface can be produced by the combination of micro-structures and a hydrophobic surface coating. By a hot stamping process we have generated differently shaped microstructures (cylinders, ellipses and lines) on polyurethane films which are afterwards coated by a PECVD process with thin, hydrophobic fluorocarbon or silicone-like films. PU films are suitable for outdoor use, because they are resistant against erosion and UV radiation.

Coatings that shed drops can help with icing mitigation. Shedding of a drop depends on surface wettability. To characterize the shedding of a drop, in an aerodynamic context, the minimum air velocity to displace the drop is measured, i.e., the critical air velocity. Recently, superhydrophobic surfaces (SHS) with their ability to shed drops have gained much attention to combat icing. However, questions remain about their performance when exposed to UV, or water for long periods. In this study of its first kind, the effect prolonged UV and water exposure on shedding of drops from 6 different SHS (four commercially available coatings (C1 to C4), and two developed in-house, S1 and S2) was investigated in an icing wind tunnel. Critical air velocity, and contact angle values show that UV-treatment has a stronger adverse effect for S1 and C1 surfaces, compared to other coatings. Water treatment adversely affects S1, C1 and C2 samples more than other samples.

Acoustic performance of auto interiors is definitely important to control the NVH performance inside a vehicle, and it is determined by the material parameters (porosity, air flow resistance, tortuosity, viscous characteristic length, thermal characteristic length, density, Young’s modulus, Poisson’s ratio, damping coefficient, and thickness). First, by making different felt samples (of different surface density and thickness), the acoustic performance and related parameters were obtained. Then the correlation between the parameters and the acoustic performance was summarized, and the sensitivity of different parameters on the acoustic performance was demonstrated. Through this method material parameter database can be established based on real materials and together with the sensitivity analysis sound package design and adjusting can be easily conducted.

In North America, about ten million kilograms of runway deicers are applied on airport runways to ensure safe takeoffs and landings of aircraft in adverse conditions. Although some of the chemicals are recovered, much of them are dispersed through aviation operations to airport’s surrounding environment. Little focus has been given into assessing and determining optimal quantities of deicers to be used on runways, that at the same time retain a high degree of safety, while reducing risks to the environment and improving airport efficiencies. Improved deicer performance tests would allow for the development of more environmentally sustainable deicers, through their improved performance. A better assessment of their deicing and anti-icing performance along with their degree of skid resistance on runway pavement, will help in the development of the next generation of runway de/anti-icing chemicals to ensure improved sustainable and safe aircraft takeoffs and landings.
