New thermoplastic composites materials

The application of new thermoplastic composite materials is partly restricted by the lack of reliable material property data measured by an independent scientific authority. To address this issue, we characterize new thermoplastic materials, as developed by our members and as appearing on the global market, in terms of performance and manufacturability.

Objective

To create a reference database for (new) thermoplastic composite materials properties in terms of processing and performance. Keywords: formability, weldability, mechanical performance, fracture toughness

Background/Introduction

The thermoplastic composite industry is growing and new materials are being introduced to the market. Selection of the right material for your application is not straightforward due to the lack of comparative data, as measured by an independent authority, between the different material systems. Reliable material property data is absolutely essential during the component design phase.  Data on processing is needed to evaluate component manufacturability, while mechanical test data is required to predict component performance.

Approach

Thermoplastic composite materials, as developed by the members of TPRC and as appearing on the global market, are assessed for their performance and processability. Characterization of mechanical properties is performed according to the relevant international standards for composite materials testing, while the material’s complete (thermo-mechanical) process history is carefully taken into account. Typically, a mechanical screening program includes measurement of tensile, bending and compressive properties, as well as interlaminar fracture toughness values. In-house developed test methodologies and set-ups are used to characterize the processability of continuous fiber reinforced thermoplastic composites. A typical test program to characterize the formability for example includes measurement of the shear and bending rigidity as well as tool-ply and ply-ply friction of the material at processing conditions. The obtained material property data can be used for predictive forming simulations, using dedicated software such as Aniform.
