The Indian passenger vehicle market has grown by more than 40% by volume in the last decade and has reached a record high in FY23. This has created a more diverse and demanding customer base that values interior design and quality. The modern customer expects a high level of aesthetics and sophistication in their vehicle interiors - including in the luggage area. The Luggage Cover (Parcel Tray) is a component in the luggage area of a passenger vehicle that is used to conceal the luggage & improve its aesthetics. The cover is generally made of thermoplastic material with rotating hinges and is held in its place by the compression from the back door, which is frequently opened and closed. The parts that connect the cover to the door (usually an elastomer interface on the thermoplastic tray) tend to change over a period due to climatic conditions and leads to rattling concerns over a period.

Increasing customer expectations of comfort and convenience inside the vehicle has resulted in OEMs working on various solutions to improve interior ergonomics and overall layout. One of the key areas of focus has been the ease of ingress into and egress from the vehicle. But with increased sharing of platforms in OEM Model Lineup, due to obvious benefits like cost and common tooling/parts, it is very difficult to achieve improved results in different vehicles (like Hatchback, Notchback, SUV etc.) but with same underpinnings. One of the commonly used approaches is provision of false flooring via floor pads for front / Rear Passengers for easy Egress-Ingress. Floor Pads are used to maintain similar comfort levels across different vehicles sharing common platform and to maintain similar relationship between Foot resting positions and Side Sill.

The aim of the research was to explore and establish aspects that affect ageing of non-woven fabrics used in automobiles. One of the most vulnerable parts in a vehicle, at the behest of the customer, is the Floor Carpet. Original Equipment manufacturers are continually binging at doable options for providing low cost carpets that are functionally and aesthetically durable throughout the vehicle life. [1] Car interiors, especially carpet, must remain in impeccable condition to uphold a good resale value. Targeting the analysis of causes that affect ageing of non-woven fabric material will form the core study of the literature to follow. The establishment of which shall ascertain some viable solutions to augment quality of the contemporary non-woven automotive carpet.

Automotive floor carpet serves the purpose of insulating airborne noises like road-tire noise, transmission noise, fuel pump noise etc. Most commonly used automotive floor carpet structure is- molded sound barrier (PE, vinyl etc.) decoupled from the floor pan with an absorber such as felt. With increasing customer expectations and fuel efficiency requirements, the NVH requirements are increasing as well. The only possible way of increasing acoustic performance (Specifically, Sound Transmission Loss, STL) in the mentioned carpet structure is to increase the barrier material. This solution, however, comes at a great weight penalty. Theoretically, increasing the number of decoupled barrier layers greatly enhances the STL performance of an acoustic packaging for same weight. In practice, however, this solution presents problems like- ineffectiveness at lower frequencies, sudden dip in performance at modal frequencies.
