Consolidating thermoplastic composite aerostructures in place, Part 1
After more than 30 years of development, in-situ consolidation is nearing its promise to eliminate fasteners and the autoclave, and enable an integrated, multifunctional airframe.

Fraunhofer ICT in-mold pressure sensors for HP-RTM
Pressure sensor-based mold fill expected to maximize part consistency and minimize cycle time for auto industry molders.

Five more exciting months in composites for 2017
As I write this column, we in the Northern Hemisphere are experiencing the “dog days of summer,” that period from early July until late August when outdoor temperatures and humidity are the highest, and, it seems, business activity is at its lowest.

Plant Tour: Fraunhofer ICT, Pfinztal, Germany
This wide-ranging research center works with government and industry to develop the best of polymer composite processing, across a range of technologies.

A look inside Fraunhofer ICT
Fraunhofer-Gesellschaft (Munich, Germany) is the largest applied research organization in Europe, with more than 67 institutes and research units located throughout Germany staffed by 24,500 people, mostly scientists and engineers. CW recently got a chance to tour one, Fraunhofer ICT in Pfintzal, Germany. 

SMC in transportation

SMC: Old dog, more tricks
In the sheet molding compound renaissance, the advent of new resins and compounds are broadening the definition and application of this versatile family of composites.

Preforming goes industrial: Part 1
ATL and AFP-based options now abound for processing dry and/or impregnated reinforcements as quickly as 1 minute or less with potential yearly part yields in the millions.

Preforms to parts via Quilted Stratum Process

Automated preforming: The numbers and landscape
CW’s multi-blog series on preforming begins with an overview and quick look at the numbers: 1-min takt time, 10-15 seconds per layer, 490-kg/hr and 3.5 million parts/yr. Are you ready for serial CFRP production?

TxV Aero Composites using Dieffenbacher tape laying system for larger-scale production
Applications within the aerospace industry include loaded clips and brackets, interiors and seating among other commercial aircraft applications.

500,000 parts per year? No problem!
BENTELER-SGL develops fully automated HP-RTM production of the weight- and space-saving composite leaf spring for Volvo’s multi-model SPA global platform.

Compression molding: New materials and markets
From multifunctional aircraft interiors to compounds using continuous fabrics to the growing use of recycled carbon fiber – compression molding offers new opportunities.

JEC World 2017 exhibit preview
JEC World will be held March 14-16 in Paris. CW previews some of the products and technologies that will be at the show.

Small companies, long-term impact
In a time known for owner “exit strategies,” longevity in family-owned composites businesses is heartening.

BMW 7 Series Plant: Dingolfing, Germany
Via four different manufacturing methods, CFRP goes mainstream in automated multi-material BIW and assembly operations at BMW’s busiest plant.

LG Hausys invests in HP-RTM machine from KraussMaffei
The machine is producing advanced structural components for the visible part of automobiles, including a CFRP roof panel.

Wet compression molding
Old process updated and automated to offer lower cycle time and cost in BMW 7 Series plus potential for void-free, 65% fiber volume composite parts.

Turnkey manufacturing systems: Simplifying automated HP-RTM
Having offered turnkey systems for composites since the 1990s for sheet molding compound (SMC), long fiber thermoplastic (LFT) and glass mat thermoplastic (GMT), Dieffenbacher (Eppingen, Germany) now has automated systems for high-pressure resin transfer molding (HP-RTM).

Turnkey manufacturing systems: Materials, markets and maturation
Automated production cells promise affordability and less risk in scaling up composites production, but are they really the path forward?

Compression molding for thermoplastic or thermoset composites
Dieffenbacher (Eppingen, Germany) introduced a new series of presses, called Compress Lite.
