Caravan Composite Panels
High-quality composite panels improve RV performance
As a new material for caravans, fiberglass (FRP/GRP) composite panels are becoming more and more popular with manufacturers and users. It replaces metal and wood and greatly improves the performance of caravans. With the increasing market acceptance, many RV bodies are also built with this material, such as motorhomes, expedition trucks, C-class motorhomes, truck campers, teardrop RVs, etc.

One-piece Caravan Composite Panels
Many fiberglass composite panels for caravans have problems such as warping and delamination, which is because the core material and the skin are not fully combined during the panel compounding process. Our sandwich panels are composites in a high-pressure vacuum environment, and the glue is evenly distributed between the core material and the skin. Our large operating platform makes it possible to make larger and flatter panels with a maximum width of 3.2m and a maximum length of 12m, so that each side of the caravan body is composed of a single composite panel. The entire caravan body consists of a front panel, a rear panel, a left panel, a right panel, a roof panel, a floor and several partitions, which makes assembly work simple.
Fiberglass Facing
Using fiberglass sheets instead of aluminum or wood as RV siding is a breakthrough and innovation in the pursuit of extreme performance. It combines many factors such as lightness, waterproofness, insulation, heat preservation, durability, and aesthetics. It makes RV construction faster and more efficient, and brings users a more comfortable RV interior environment and lower maintenance costs. The surface of the fiberglass sheet is coated with gel-coat, which is absolutely waterproof. It can usually be processed into a variety of color effects such as glossy, matte, embossed, etc.
Core Materials
From the perspective of insulation, strength, weight, cost and other aspects, different types of RV sandwich panels have different choices of core materials. Commonly used core materials are hard foam, honeycomb sheets, and plywood. For example, panels that require insulation will use foam as the core material; RV bodies that require lighter weight usually choose honeycomb panels as the core material; and using plywood as the core material can increase the strength of the panel and greatly reduce the construction cost.
How to Enhance the Strength of RV Sandwich Panels
Sandwich panel structures that only rely on fiberglass sheets and core materials cannot provide stronger strength support. This is more obvious in foam core fiberglass sandwich panels. To have a stronger panel means adding stronger materials. Usually we will make a “skeleton” for the sandwich panel, which is embedded in the foam core. These materials are commonly waterproof wood, high-density foam, aluminum profiles, fiberglass profiles, etc. Another point is that we will add a layer of energy-absorbing material between the core material and the skin, which not only increases the strength of the panel but also improves the smoothness of the surface.
CNC Machining
After the composite panel is manufactured, it needs to be post-processed to obtain the designed shape, more accurate size and better appearance. CNC machining can better complete cutting, pinning, milling, drilling and other operations, and maintain consistency of precision.
