Laminate and Composite

LDP Aerospace developed and carried out many analyses for aeronautical, automotive, and naval Companies in Italy and Europe. LDP Engineers have a great experience in laminate and composite materials, and applies its know-how to bring superior quality to its Customers.

A laminate is a multi-layered, fiber-reinforced composite. The most common laminate is a matrix material (glue) reinforced with some fibrous material. LDP defines the materials for laminates and specify laminate properties. Laminate material matrices define the material properties of layered composite materials. The properties are formatted to allow for efficient construction of laminated shell finite elements. Laminar material matrices are generated and then related the shell stress resultants to the generalized strains in the shell.

The basic steps for defining a laminate and performing an analysis are:

1. defining the material properties that represent the matrix and fiber properties that make up the plies
2. creating a ply material, defining properties such as matrix and fiber volume fractions and ply thickness
3. performing loads analysis to determine if the laminate has the desired characteristics
4. applying laminate properties to the FE model and performing a finite element analysis
5. solving and analyzing the results of the laminate model
