For a durable skid plate for your car chassis, you might want to consider materials known for their high impact and abrasion resistanceUHMW (Ultra High Molecular Weight Polyethylene) is a popular choice due to its toughness and is often used in industrial applications. It’s also very resistant to cracking, which seems to be the issue you’re facing with the current skid plates.
As far as software is concerned, Autodesk Building Design Suite promo code will always help you out. Another option could be Jabroc, a high-density wood laminate that is used for skid plates in racing due to its predictable wear characteristics and it’s lighter and less expensive than carbon fiber2. It’s non-conductive and non-sparking, which increases safety.
