Physical properties of plastic laminates


Plastic laminates are a mixture of resin and fiber and are a class of so-called hybrid panels. A mixed plate is defined as a physical mixture of two or more different materials. Plastic laminates are perfectly suited to this definition.
Physical Properties: The physical properties of a laminate (ie, a hybrid panel) are typically in the intermediate state of its individual component properties. As the resin to fiber ratio increases, the performance of plastic laminates approaches that of pure resin properties: for example, hard, reduced resin content, resulting in more fiber-like properties: for example, flexibility, poor water resistance, and the like. An important property imparted by brittle, water resistant resins is water resistance. This performance makes for the merchandise. For example, decorative laminates have a practical lower limit on the resin content. For example, a decorative laminate must have a moisture intake of less than 10% after a 2 h cooking test. Industrial laminates, especially those intended for electrical applications, have more stringent requirements. In order to meet these requirements, it is often necessary to use a resin having a relatively high hydrophobicity (for example, an epoxy resin or a silicone resin) and/or a fiber having a relatively low hydrophilicity (for example, glass fiber, nylon or polyester).
The breaking strength of a plastic laminate depends on the strength of both the resin and the fiber and the bonding force between the two. This relationship is complex and not simply related to the variables of the developed formula.
